Safe disc for wood. Selecting a wood disc for an angle grinder or grinding angle grinder. Attachment for grinder for brushing wood
An angle grinder, if you know and correctly use all its capabilities, is a truly universal device that can be used on almost any material. And if we are talking about processing wood on a large scale, then the “grinder” is much more effective than hand-held abrasive tools and devices. The main thing is to choose the right nozzle. This article will help you understand their main modifications and specific application.
Rough stripping of wood
Disc plane
This attachment almost completely replaces this hand tool.
An irreplaceable thing if, for example, you need to rough-process a log - when erecting a log house, preparing fence supports, and so on.
Features of application:
- In this case protective cover can be removed. This nozzle is solid and does not collapse. But protection from flying wood chips (glasses, thick clothing, mittens) is required.
- It is allowed to work only with a grinder, in which a second handle is provided (or installed). The angle grinder must be held with both hands when roughing wood.
Roughing disc
The main purpose of such attachments is to remove bark from wood and trim the workpiece. If the "grinder" is in in capable hands, then with such a device you can make a sample of material. For example, if it is necessary to cut out a bowl. If it is being built log house, then an angle grinder with such an attachment perfectly replaces a carpenter’s axe.
In some cases abrasive disc cutting can be done. True, the cut will be wide, and there will be a lot of waste (shavings, sawdust).
Milling
Discs
These nozzles are available in various designs. The main difference between the devices is the size of the abrasive grains.
In terms of specific application, they are not much different from rasps. The only difference is the speed of the technological operation. With certain skills, it is advisable to use these for finishing wood.
Milling cutters
They exist, and especially for wood. The assortment is significant, since nozzles of this type differ in the configuration, location and size of the teeth.
Purpose of cutters:
- Selection of grooves.
- Pre-alignment of edges.
- Bowl cutout.
- Sawing (for wooden blanks small section).
Application specifics:
- When processing wood with such attachments, it is prohibited to dismantle the protective casing.
- Each product has instructions. It clearly indicates what types of work this attachment is intended for, the recommended speed of the grinder, and so on.
Sanding wood
If you decipher the abbreviation angle grinder, it is clear that finishing is the main purpose of the “grinder”.
Cord brushes
They are used primarily for primary (rough) sanding of wood, when it is necessary to smooth out the unevenness of the sample.
End discs
The name speaks for itself. These attachments are used to process the end parts of wooden blanks (cuts). They are especially effective if you have to deal with corner (oblique) cuts.
Petal attachments
The most used grinding devices for grinders.
Such attachments are used sequentially, so you will need several of them to process wood. Grinding begins with a disk with a “coarse” abrasive, and gradually its grain size must be reduced. Consequently, the devices change periodically during the work on the grinder.
Grinding wheels
Most universal device to the "Bulgarian". It alone is quite enough for varying degrees of grinding. The attachment itself is a metal base on which circles with one or another grain size are attached. They are easily changed either as they wear out, or in case of moving to another area of work. Therefore, only circles are consumables. The nozzle itself can be used for an unlimited time.
Application specifics:
- Sanding wood.
- Parquet scraping.
- Processing of edges and ends.
- Stripping wood before painting.
Wood polishing
For these purposes, brushes and discs are used. Their “working elements” can be made of sponge, felt, fine-grained “sandpaper” and a number of other materials.
The article provides examples of only the main types of attachments for an angle grinder. There are quite a lot of products in this class, so it’s easy to choose best option devices for processing any wood. The author hopes that the information provided will help the reader with this.
Note!
Wood processing also means its cutting (sawing). Sometimes, when manufacturing piece parts, you have to adjust them to the installation site even before you start grinding the sample. Some “craftsmen” (and there are many of them among friends and on the Internet) recommend using for such operations. Strictly prohibited! Here are just the main reasons why this should not be done.
- “Bulgarian” is a high-speed machine. And although the metal from which the cutting discs are made is durable, it does not withstand this mode for long. More precisely, cutting edges(teeth), which are fixed by soldering. During intensive work, they fall off and fly apart, and with great speed. The consequences are easy to predict.
- Not all discs in size (primarily, outer diameter) are suitable for installation on angle grinders. This means that you will have to dismantle the protective casing. The same thing - you can forget about employee safety.
- The structure of wood (even hardwood) is quite loose. Therefore, there is a high probability that the saw blade may jam due to constant vibration. How the “grinder” will behave in such a situation, given its power and speed, no one can predict. But it’s clear that it can easily escape from your hands.
- Constant changes in mode (for the same reason - the viscosity of lumber) lead to systematic overheating of the angle grinder engine. If used this way, the grinder will not last long.
That is why wood processing with its help is carried out only superficially - rough stripping, grinding, brushing. And for cutting you should use sawing tools and mechanisms (hacksaw, circular saw, electric jigsaw, and so on).
A power tool familiar to working with metal, an angle grinder is also effectively used for processing other materials. Many people put a wood disc on an angle grinder without thinking about safety precautions.
Is it possible to cut wood with such a disk and what types? auxiliary tool they come to the grinder, let's figure it out.
There are special wood cutting discs designed for this type of work, but this is rather the exception. In addition, such a disc is not suitable for every angle grinder.
Let's consider several options.
Saw blades, hybrid chainsaw blade and chain
These cutting discs can be used to cut boards up to 40mm thick, with extreme caution. Rules, non-compliance with which lead to injury:
The saw blade has a metal base and a chainsaw chain attached around the perimeter
- It is strictly forbidden to remove the protective cover if the diameter of the disc exceeds the dimensions of the casing - your angle grinder cannot be used.
- Corner grinding machine should operate at the speed indicated on the disk. Otherwise, the chain may jump off and its components may fly apart.
- Safety glasses and thick gloves are required. It also doesn’t hurt to wear thick canvas clothing.
IMPORTANT! Use regular disks for circular saw, on an angle grinder is strictly prohibited.
The same applies to diamond cutting discs for concrete. For cutting work wooden products they are unsuitable and dangerous. Firstly, the operating efficiency is extremely low, especially considering the cost of the disk. Secondly, you can simply burn the workpiece.
And finally, such a disk can jam in the cut at any moment, and you will receive a blow from the body of the angle grinder. Here is an example of a grinder blade that can be used to cut wood with extreme care.
The design of the circle provides protection against jamming with the help of side teeth that expand the width of the cut. The disk has a diameter of 115 mm, and its dimensions allow you to work without removing the protective casing.
The wood blade fits completely under the protective cover
Some home-grown “masters” adjust standard circular saw blades to fit, the work is done with the protective cover removed. Most often, such experiments end tragically. The would-be master receives severe injuries, and possibly death.
At the same time, on construction markets full of suggestions for saws for grinders on wood. Sellers will assure you that in the hands of a professional, using such a tool is completely safe. This statement is true as long as these very hands are intact and unharmed.
It's like the fairy tale about the unicorn, everyone has heard about it, but no one has seen it with their own eyes. The public of construction forums and authors of similar articles on the Internet is divided into two camps. The former say that during their lives they have cut through more than one cubic meter of wood with a grinder, the latter give strong arguments in favor of the fact that after such work you can lose your fingers or limbs, or even worse. Is there a disc for an angle grinder for wood, and if so, what does it look like and is it safe to use?
The author of this article kindly asks you not to consider this material as a guide to action. Angle grinder is not intended for working with wood, even those manufacturers who produce discs and cutters for wood write on their official websites that it is extremely unsafe to cut wood with a grinder. But you and I know that people rarely think about their health first.
Cutting with an abrasive disc
Yes, you can cut wood with a metal disc; to be honest, I myself have done this more than once while working at a construction site. What can we say? Well, firstly, the speed of work with this method is low. Secondly, the smell of burnt wood even on outdoors within a radius of 10 meters you are provided. And thirdly, the thickness of the sawn board should not exceed four centimeters. This is not to say that abrasive disc It is not a wood saw for an angle grinder; its main purpose is to cut metal. As for the advantages, in my opinion these are: the absence of sawdust, and a smooth, even cut.
Circular saw blade and its improved analogue
The vast Internet is full of videos on how to turn a circular saw blade or a diamond blade for concrete into a blade for working with wood. You can argue for a long time about whether this is worth doing or not? Even without considering myself awesome smart person, I would not conduct such experiments. And here's why:
- The circular saw blade is not designed for high speeds; yes, it is carbide, but no less fragile. One chipped tooth can pose a great danger to a person.
- The edges of the toothed disk are not smooth; when cutting into a tree, the grinder will vibrate and crash into the branches of the workpiece. This type of work may cause the operator to lose control of the tool.
- the likelihood of a kickback increases
There is an adapted blade for a wood grinder on sale; the manufacturers claim that due to the shape of the tooth and the special expanders that are located on the cutting part of the blade, all of the above concerns about the tool jamming disappear. One of the manufacturers is the Rotarex company; in its assortment you can find both grinding and cutting discs for grinders. Below is an image of a circular saw disc and a grinder disc from Rotarex, which is universal. They can cut not only wood, but also aerated concrete.
Chain disk for wood for an angle grinder
At first glance, it may seem that this is a device for a horror film, but judging by the reviews of its owners, this disc is safer than the analogues presented above. It is a solid circle, along the edges of which there is a chain from a chainsaw, everything is made of high-quality tool steel. The main purpose of such a disk is: milling, modeling, stripping wood of bark and cutting out cups in logs for log houses. It is also possible to cut with such a disk, given that the cutting width will be about eight millimeters, since the thickness chain disk is six millimeters. Speaking of diameters, there are 125 and 230 wheels on sale. Operational life such a disk will be many times larger than others, because it can always be sharpened with a file. The price for them ranges from two to three thousand rubles, and with delivery from another region it will cost even more.
Remember safety!
No matter what kind of disc you work with and no matter what material you cut, you should always remember that following safety rules can save not only your health, but also your life. And before you start working, read the following points:
- do not work while intoxicated;
- use safety glasses and protective clothing when working;
- Do not remove the protective cover under any circumstances;
- It is prohibited to use a defective one cutting disc or a disk with some, even minor, defects;
- When working with an angle grinder, hold it with both hands;
- the electrical cord must be kept away from the rotating disk;
- Do not put down the tool until the disc comes to a complete stop.
There are a lot of ways to cut wood, one of them is to make a cutting disc out of paper. How effective this is, of course, is up to you to judge, but please note that this is one of the safest options.
An angle grinder (angle grinder), popularly known as a “grinder”, is a professional universal device that is used for a variety of purposes. With its help you can carry out many works: cutting, grinding, polishing, sawing and processing various raw materials. When choosing a suitable model, you must understand its design features, assess your financial capabilities, and also consult with a specialist.
Due to the great variety existing models, choice perfect solution could be a real disaster. In any case, the emphasis should be placed on the purpose of the proposed equipment. Wooden structures need appropriate grinding wheels for wood grinders. The same goes for metal - it is processed only with suitable tools.
Types of grinding discs
Currently, a wide variety of grinder discs are offered for sale, and the common man may find It’s not at all easy to choose a grinding wheel for a wood grinder. To understand in more detail existing types, it is necessary to divide the assortment into the following categories:
- Abrasive type wheels. Like consumables It is particularly versatile, so it allows you to carry out precise and high-quality activities with minimal resource consumption. In addition, there is the possibility of additional polishing. Due to such characteristics, abrasive type tools are among the best.
- Diamond coated wheels are very popular. Segmented and solid models are available in the market. Depending on this option, the scope of application may differ. Both solutions are capable of providing precise cutting of any materials with the highest density. These include: stone, metal and concrete products.
Grinder wheels may resemble most modern saws, however, they are made of other alloys. Initially, such goods were considered rare, but now they have spread very widely. Ideal option- a combination of carbide and tungsten.
Woodworking discs
If you intend to purchase a wood saw blade for bolarka, be sure to study the basic operating principle of such a device. What features should be taken into account when purchasing a blade for an angle grinder for wood?
First of all, you should pay attention to the different standard diameters. The most compact solution has a size of 115 millimeters. However, many experts prefer to buy a 125 mm wood blade for a grinder, which is explained by its great practicality. In addition, angle grinders are used on 125 laps special demand not only among representatives professional fields, but also among home craftsmen.
It is no secret that a material such as natural wood is a specific heterogeneous raw material, so its processing requires the use of various circles. Use classic models for metal or concrete structures is strictly prohibited. If you don't take this into account, the tool will simply fail or burn out.
When choosing suitable products for grinding, pay attention to the diameter of the installed shaft. The standard value is 22.2 millimeters. Initially there were several divisions, so the significance of the marking remains quite large. Currently, most standard models have a diameter of 125x22.2 mm.
And although the permissible size of an angle grinder is 230 millimeters, it is not advisable to give preference to such sizes for wood processing. When handling large items, you expose yourself to the risk of dangerous damage and injury. Ideal sizes represented by a range 115×22.2 - 125×22.2 millimeters. And class 125 wheels are the most versatile, so they can be used to solve a wide range of production operations.
After carefully studying the specifics grinding discs for an angle grinder on wood, you can proceed to the search suitable models, which will ensure the safest and most effective processing of such valuable material like natural wood.
Types of cutting wheels
When purchasing a cutting disc, take a responsible approach to choosing the “right” model and pay attention to a number of design indicators. Among them:
- circle diameter.
- wood cut depth.
- features of teeth (shape, number, frequency).
If you want to use a cutting disc, consider the following recommendations:
To avoid making a mistake in choosing the right solution, pay attention to following features choice saw consumable tools.
- It is necessary to choose rounded cutouts that are made strictly towards the shaft.
- Optimal thickness disk is equal to two millimeters.
- The depth of the cutouts sometimes reaches 20 millimeters.
- The cutout may be empty, but in some cases it is filled with a copper compound.
Required Equipment
In many cases, working with materials involves carrying out polishing, grinding and roughening procedures.
It's no secret that cutting wood is a very dangerous task, but even an inexperienced worker can sand solid wood. The main thing is that he has the required equipment at his disposal. Enough to deal with basic principles upcoming work, and everything will be successful.
In most cases, for peeling they use petal discs. After carefully studying the specifics of the product, you can be convinced of its functionality and effectiveness.
From the name you can understand, what are the features and operating principle of the consumable tool. His work area may have a small number of sandpaper petals. This structure may resemble fish scales. As for papers with low roughness, they provide soft sanding of elite wood species.
Quality indicators and the degree of processing are determined by the grain size of the material, therefore polishing and grinding are carried out taking into account the established requirements.
Despite the great popularity of petal models, you can use other consumables. For example, very good decision can become a multi-purpose sticky disk. Most modern attachments have the ability to quickly change Velcro. The cost of the adhesive discs used is much lower than the cost of solid flap discs, however low price characterized by a short service life. In any case, universal sticky models are effective both in processing and sanding the most various materials, which explains their great popularity.
Tool characteristics and work quality
Even if you purchased the most expensive polishing and grinding equipment, this does not mean that the quality of work will be maximum. What is this connected with? It's very simple: for successful processing you need to use exclusively dried wood. Raw material is unsuitable for this type of event. If you do not take this feature into account, the result may not be the most pleasant. When choosing a wood blade, make sure that the selected raw material meets established requirements and standards.
In some cases, it becomes necessary to carry out cleaning work to remove the old layer of paint, varnish or fungal formations. Good polishing and sanding tools always work in the best possible way, however, provided that the material is prepared taking into account basic technological requirements. You must understand that polishing and grinding discs for angle grinders are not suitable for primary processing operations, so they must be equipped with additional abrasive attachments.
When choosing a suitable nozzle, you will be able to feel their effectiveness in those cases where you need to carry out cleaning old surfaces, which are covered with several layers of paint. This result can be explained very simply: most nozzles are a kind of metal plate on which there are wire bristles placed closer to the outer circumference in a radial or perpendicular manner to the disk.
Finishing operations begin in cases where the workpiece takes on preliminary shape. The final result can be determined by the types of attachments that are used to solve the problem.
An angle grinder can be used as a cutter, as well as a grinding and polishing machine. Expanded functionality is provided by using different types disks.
And so, if you are faced with the question: “how to successfully polish or sand a wood structure,” be prepared to take a responsible approach to studying the basic subtleties and recommendations. As for the tools that will be applied later, they include:
If you intend to choose the right equipment for an angle grinder, consider not only the diameter, but also many other markings. Using the inscriptions, you can clarify the exact purpose of the tool and select best option for your own purposes.
The modern grinder is one of the most convenient and useful devices . To improve the quality of its work, you need to take care of additional attachments and discs that will make the processing of wood, metal, or any other raw material accurate and complete.
An angle grinder, whose real name is an angle grinder, is a universal tool. They almost never do without it construction work. But in order for the tool to last a long time, it is necessary to select the correct grinding discs. A disk for wood is fundamentally different from a disk for metal. What are its features, and what varieties are there?
Today, the entire range is divided into three main areas:
- Saw blades. They resemble a regular saw, but are made from completely different materials. Until recently, such specimens were hard to find, but now they are sold completely freely. The most preferred option is tungsten carbide.
- Diamond coated disc. The most popular variety. In turn, it is divided into solid and segmented. Their scope is different, but there is common feature— high-quality and accurate results of work on concrete, metal or stone.
- Abrasive. Universal consumable, suitable for any type of surface. It cuts, grinds and polishes well.
Of the listed disks, the first and second are not suitable for wood. Natural wood has a very dense structure, and if you use a diamond disc, the grinder will overheat to the point of breaking.
The products also vary in diameter. The most practical ones have a diameter of 125 mm; in rare cases, a compact disk is needed - 115 mm. There are specimens up to 230 mm, but they are not suitable for wood. Their use may cause injury.
Selecting cutting wheels for wood
Cutting discs are divided according to three parameters - diameter, depth of cut and shape/frequency of teeth. Choosing the right option, there are a few things to consider: how often the product will be used and for what type of wood.
Coniferous and other soft woods can be easily cut with a straight-toothed blade. If you plan to cut different wood, it is better to take a universal circle with variably beveled teeth. There are also trapezoidal teeth that are ideal for cutting through wood. medium density and woody areas.
Selecting grinding and polishing wheels
If cutting a material requires certain skills, then almost anyone can grind. Flap discs are usually used for this operation. Such a disk consists of several sandpaper petals arranged in a circle. Sandpaper provides a gentle sanding effect.
Another option is a Velcro abrasive disc. It is convenient to use, but even more convenient to change. Such circles do not last long, but also have a low cost. And, of course, they are many times more effective manual method processing with sandpaper. For example, using such a circle you can polish parquet.
Preparing the tree
Whatever the blade for the grinder, the work cannot be done efficiently if the wood is not properly prepared. Here are some tips on this matter:
- the wood must be thoroughly dried;
- special abrasive attachments are suitable for removing paint or varnish from the surface;
- the work is carried out in two stages, roughing and finishing.
Discs and other tools that will be needed for complete sanding or polishing of wood:
- Cord brushes designed for rough grinding surfaces. They help give the product an acceptable shape.
- The next step in processing a piece of natural wood is to use sanding attachment. If the subject is complex, you will also need to apply radial stripes.
- A felt circle made of pressed wool (coarse, fine or semi-coarse) will help get rid of the slightest roughness. With their help, the surface can be made almost mirror-like.
As you can see, when using various attachments, the grinder becomes universal tool for woodworking.
Saws (chain wheels)
Suitable for cutting boards less than 4 cm thick. Use requires extreme caution. During non-working hours, the disc must be kept in a case, and during operation it must be used only at the speed indicated on the product itself.
Also, goggles and protective gloves are required when working. It is important to remember that under no circumstances should you use regular circles designed for a circular saw on an angle grinder.
Using an angle grinder for milling
A wood cutter for an angle grinder can be dangerous in unprofessional hands. For a specialist, its use is acceptable.
The milling cutter helps to level the edge, make grooves, cut workpieces and cut out bowls for log houses. Even on non-uniform wood, the tool will not jam or throw off. However, before starting use, it is important to carefully read the instructions and also observe the required speed.
The choice of cutters for angle grinders is quite wide, no less than for a manual milling machine. They are not intended for precision machining, but are quite suitable for shaping.
Safety rules during operation
In order for the use of a wood disc for an angle grinder to bring only benefits and not injury or damaged products, you must follow several important rules:
- choose the right circle according to size and properties;
- The operating mode of the machine must correspond to the requirements on the disk;
- Damaged wheels should not be used under any circumstances;
- protect your hands and face special devices and special clothing.
The attachment should fit effortlessly under the angle grinder casing. If you can’t do this, then do not remove the casing, it is dangerous.
Why can’t you use saw blades with an angle grinder?
The hardness of wood can vary even within a few centimeters. It may also contain clumps of resin and knots. All these uneven areas lead to the saw blade stopping abruptly, as a result of which the grinder is torn out of your hands.
