Tips and Uses + Videos Life hacks with a grinder + photo and video. The grinder is a versatile tool, and it can be used to perform a huge amount of all kinds of work. It has become indispensable for various fields, in particular for construction and metal processing. With its help, it is possible to increase labor productivity. The emergence of a huge number of different attachments has led to the fact that the functionality of the device has expanded and its capabilities, too.

But not all workers know how to use a grinder correctly, even if they regularly use it for their activities. It should be borne in mind that if you do not follow even the elementary rules of safe handling of a grinder, this can be fraught with extremely dangerous injuries, which sometimes even end in death. To avoid this, you will need to follow the operating instructions. It is important to choose the right discs for cutting and grinding, so we suggest considering the features of using the tool and life hacks with a grinder with your own hands.

Operations that can be performed using a grinder

An angle grinder (grinder) is a tool with many functions.

The drive mechanism in it is presented in the form of an electric motor, which, through a gearbox, begins to transmit movement to a shaft with a replaceable nozzle attached to it. A general view of the device is shown in the photo below. There are different models on the market and in hardware stores,

which differ from each other in design and power:

  • Household devices.
  • Professional.
  • With or without handles.

Powerful devices will be powered from a three-phase voltage, the value of which is 380 V, and household devices from a standard single-phase network of 220 V. An angle grinder will help to perform the following basic types of work with various building materials:

  • Cutting.
  • Polishing.
  • Grinding.

Interesting, that if you fix the grinder motionlessly, you can sharpen various tools on the circle, such as drills, incisors, knives and other things.

Angle grinders are designed to work with the following materials:

  • Tips and Uses + Videos Metal.
  • Concrete.
  • Glass.
  • Tree.
  • Stone.

  • Ceramic tiles.
  • Plastic.
  • Brick.

Grinders have become extremely popular in everyday life, as well as in industrial conditions. This is due to the fact that they have wide functionality,

and is due to all of the following factors:

  • Huge selection of different attachments from all kinds of materials for various operations.

  • Possibility of creating a fixed fixation using special attachment devices.
  • The presence of additional handles in certain models, as well as several speed modes for performing work.

In this case, be sure to remember that for processing each of the materials you can use only special discs.

What is the danger of an angle grinder

In addition to the fact that there are many life hacks with a grinder, angle grinder is a traumatic electric tool.

This is due to the following reasons:

  • High rotation speed of the working nozzle - can exceed the speed of 10,000 revolutions per minute.

  • Openness (unprotected casing) of most of the disc.
  • Ability to break the abrasive disc into fragments of different sizes, which will be scattered on all sides with great speed.
  • Partial inability to properly organize the workplace.
  • Formations when cutting metal (or other materials), when grinding small particles.

If the disc starts to jam, even if due to a slight skew, the grinder will be almost impossible to hold in your hands, since the tool is powerful.

This is because the rotation speed is high enough. For this reason, it is better for beginners to work with models that have low power, which are equipped with discs with a diameter of 11.5 to 12.5 cm.By the way, the latter should in no case have defects that can lead to unexpected destruction and tearing out of an angle grinder from hands with irreparable consequences.

General safety rules

In order to reduce the likelihood of injury when working with an electric tool, the grinder should be handled correctly.

In this case, the following rules of use should be observed:

  1. First, you should buy personal protective equipment. The user's health must be in good condition.
  2. Before starting work, it is required to check the reliability and correctness of the casing attachment so that it does not fall off in the process, and sparks do not start flying into the operator.
  3. Use only complete discs that are free from defects (chips, cracks or fractures) and only for their intended purpose - in order to process specific materials.

  4. A protective shield must be placed between the circle and the operator so that you have protection when the circle is destroyed.
  5. Before starting work, you should check the performance of the tool when idle for about 1 minute - uniformity of rotation at maximum speed, absence of vibrations and other things.
  6. Before use, inspect any attachments to determine suitability for use.
  7. An interesting life hack for the grinder, or rather its use - protect objects from sparks with an asbestos or ordinary damp cloth so that oily rags, paper, fuels and lubricants, ropes and solvents do not ignite.
  8. You will need to securely fix the working attachments to prevent them from falling off.

  9. If it is possible to adjust the speed of rotation, set the speed that is recommended for cutting or grinding work material.
  10. Be very careful when sawing wood, as hitting a branch can cause the angle grinder to jerk out of your hands.
  11. Do not attach attachments to the circular saw tool, as they are designed for other spindle speeds.
  12. Always hold the tool with both hands.
  13. When you start to work, you should remove all unnecessary and make sure that there are no foreign objects on the cutting plane, except for the part you are processing.

  14. Take regular breaks from work.
  15. If the working attachment is stuck, turn off the tools immediately.
  16. Be sure to maintain a balanced (i.e. stable) body position.

  17. The power cord must be kept away from the rotating part to avoid being cut by a short circuit.
  18. Only after the wheel has come to a complete stop can the tool be released.
  19. When moving around the workplace, turn off the power tool, and also do the same when turning off the supply voltage.
  20. Cut only at full revolution.

The stated life hacks and security measures were developed by tool manufacturers, as well as with the help of special services that deal with the activities of labor protection.

Please note, that in order to ensure the safety of work, it is better to buy not the cheapest materials, but those that are of better quality from a reliable manufacturer. A person who works as a grinder must be adequate, in a balanced psychological state.

Wearing Protective Equipment

When operating the angle grinder, users should wear the following personal protective equipment:

  • Safety goggles or a mask that will cover your eyes on all sides.
  • Gloves made of leather or at least dense fabric.
  • Specialized footwear (stable, whole) and work uniform.

  • A respirator that will provide you with protection of the respiratory system from small particles when cutting concrete, ceramic or glass slabs, porcelain stoneware, brick, stone, foam block and other dusty materials.

Personal protective equipment must be worn when working with the angle grinder. This will give you the opportunity to work, but safely. Let's look at life hacks for a grinder, or rather, how not to work with these electric multifunctional tools.

How it is impossible to perform work with a grinder

Safety when using the device must be in the first place, and according to it you prohibited:

  • Perform work manipulations without personal protective equipment.

  • Work only in light clothing that does not completely cover the body (legs, arms).
  • Use a machine that does not have a cover to protect against flying sparks.
  • Without checking the tool for the ability to work, start using it at idle.
  • Work with a defective disc, or one that is unsuitable for the material being processed.
  • Be in the cutting plane.

  • Press down firmly on the power tool.
  • Work so that the direction of rotation of the wheel is towards the operator.
  • Doing work and not taking breaks for rest, as hands will get tired anyway, and after that it will be difficult to hold the grinder tightly.
  • So that the machined workpiece is not secured (for example, with clamps or in a vice).
  • Sharpen metal parts using the side of the disc.

  • Cut workpieces thicker than half the radius of the circle being used.
  • Stay of unauthorized persons in the working area.
  • Touch the accessories until they cool down because they overheat during grinding and cutting due to excessive friction.
  • Switch on the tool when deepening the circle into the workpiece.
  • Sand with fine discs.

  • Use attachments with a larger diameter than that for which the tool is designed.
  • Position the working area in such a way that the circle is pinched during cutting (the cut must necessarily go to break, but not to squeeze).

Safe use of the saws in the grinder will be ensured by the fact that it will be replaced only when the device is disconnected from the mains.

In which direction you can cut the material with the grinder

Another life hack for the grinder, or rather to work with it. Before you start cutting the material, you should first figure out which way the tool is spinning - sparks towards yourself or away from yourself.

There is no definite answer among users, since the device works in any form. If the nozzle rotates counterclockwise, the sparks (and the broken circle) will fly in the opposite direction from the operator, but the recoil of the tool when jammed will go to the user. In the second case, everything will be completely the opposite. According to safety precautions, it is considered that correct rotation is when sparks fly towards the user, since when jammed, the jerk of the electric tool will be in the opposite direction from the operator.

Anyway, manufacturers recommend making the movement of the angle grinder and rotation of the wheel in one direction.

This will help to greatly reduce the likelihood that the disc will come out of the slot during workflow. When using this method, the markings on the material are most often not visible due to flying sparks.

You can also change the rotation of the attachments, if you move the cover and the handle to the other side.This option will be the easiest (if you can do it). A more complicated way is to make changes in the electrical circuit diagram of the device.

But even this is not always able to help.

Note that an important point to ensure correct positioning of the work tool is that the cutting line must be on the side of the operator. In this case, in case of possible jamming, the grinder will simply pull to the side.

When slicing, do so that the work plane does not change, and there are no distortions yet. Discs must be used in accordance with the material you are processing.

So, tiles, stone and concrete should be cut using circles with different diameters, which are diamond-coated.

Nuances of cutting certain materials

When cutting concrete , use these recommendations:

  • Before starting work, check the concrete for embedded fittings, pipes, electrical wiring (using a metal detector to find wiring).
  • To reduce dust, dampen the work surface with water (for example, spray with a spray bottle or brush).
  • Cool the cutting element with water or air from time to time.

If you do not have a tile cutter, you can also cut a tile with a grinder.

Experts are able to cut even a perfectly even circle in a tile. Stone and tiles can be cut in two ways :

  • Tips and Uses + Videos Wet (wet the work area with liquid).
  • Dry (no moisture).

The first option will improve cooling, but there will be a lot of dirt, and the second will have a lot of dust. The wet method is used for large volumes of upcoming work, and the dry method for one-time cutting.

Cut the material smoothly so that the disc sinks with a slight pressure, almost under the influence of the angle grinder's own weight. This is required in order to prevent disc distortion and reduce the likelihood of jamming. If the process slows down, then you should replace the nozzle with a new one. And consider other life hacks for a grinder with our own hands.

  1. When you are cutting with a grinder, sparks are often thrown at you.

    If the clothing is flammable, it can cause injury. To avoid a problem, take a regular insole (used sandpaper or a piece of rubber), as well as silicone glue (alternatively, use double-sided tape) and glue it all to the grinder's protective casing. The advantage of silicone adhesive is that it can be easily peeled off the casing, and the result is an interesting design. This gives you a flexible extension of the casing. Such a mudguard will protect well from sparks, as long as you choose a non-combustible material.

  2. Very strong profile pipes are usually coated with oil to help prevent rusting.If your workshop has MDF, then you can make a device for stripping a profile pipe (and any other metal) from grease, as well as paint or rust. To do this, take a regular grinder disc and transfer the outer and inner diameters to the MDF sheet. The circle can be cut with an electric jigsaw, but you can also use crowns with a suitable diameter. Next, attach the homemade disk to the device and you can clean the wires.

    If you take a polish for a car, then you can polish the metal.

  3. The grinder key is annoying because it is sometimes difficult to find when you need it. There is a fairly simple way to disassemble a disc without a key, and we note that it is better to do everything with gloves and with the device turned off.

First, spin the grinder's disk in the opposite direction (on the back of the grinder, the arrow indicates the direction of rotation of the disk), make three turns with a sharp movement of your hand. Then sharply twist the disc in the opposite direction.

The nut that holds the disc will unscrew, and you can easily unscrew it by hand and remove the disc.

  1. The method is useful for cutting off the edge from a profile pipe, and so that the bottom wall is cut off at the same angle as the top one (we do everything at an angle of 90 degrees). Take a piece of metal with a thickness of 0.1-0. 2 cm and drill the hole so that it stands from the cut off disc at a distance of 0.

    2-0. 3 cm and fasten with an M8 bolt. Next, make a marking with a square, it should be marked at a right angle, and then cut off the tip of the profile pipe. Please note that this method has two drawbacks - the bolt limits the length of the cutting part, and the size of the disc limits its height.

  2. An excellent life hack if you want to cut a round pipe strictly at right angles using a grinder.

    You will need a sheet of paper with straight edges, tape, a pipe, and an electric tool. Wind the sheet around the tube, tightly, and after you have made one circle, the edges should converge perfectly. Next, cut off everything around the edge of the sheet with a grinder, and get a perfect 90 degrees.

Use the grinder only when you know all the operating and safety rules. The working part must necessarily rotate in the direction of movement of the tool.

Before starting the process, be sure to turn on the device at idle speed. Also, in this case, vibration, heating of the grinder, and also extraneous sounds should be absent. Wheels should be used without defects and kickback may be the most dangerous moment. To avoid this, try not to create a wedge on the wheel when cutting.
