Work technology

The direction in which the sparks fly depends on how familiar a person is with the technology of working with an angle grinder.

  • The first is the grip. You need to hold the unit firmly with both hands, without transferring the weight to any one hand. In a kickback situation, with the correct grip, there will be no pulling out of the hands.
  • The line should be laid out to the side away from the rotating disc, but not next to or on the mowing line of the cut.
  • The direction of the sparks can be chosen both away from the master, and under him. the main thing is not on yourself. However, left-handers do not have to choose, the only possible option is the direction of sparks “for themselves”.
  • When working with an angle grinder, there should be a bucket of water nearby as a precaution against fire.
  • The tool cannot be put off anywhere while the disc is rotating. Naturally, when moving from one place to another in operation, the angle grinder must be turned off.

The conclusion of the direction of the sparks from the angle grinder depends on the master, to choose from either himself or for himself.

Which way should the sparks fly from the angle grinder?

In other words, how to properly set up an angle grinder so that you can work with it simply, conveniently and safely!

Kick back

The most common and dangerous moment of working with an angle grinder is the occurrence of kickback, which is characterized by an instant and very sharp throw of the tool towards the operator. The force of impact is so great that it is simply impossible to hold an angle grinder in your hands. this is especially dangerous if the work is carried out at head level. Kickback injuries can be severe enough to be fatal.

The kickback can be caused by the use of a non-working (deformed or damaged) working disc and / or its jamming in the material. Very often, the kickback occurs at the final stage of the cut, when it remains only to finish the last layer of material that connects the cut parts. In this case, it is recommended not to finish the cut from the same side, but to execute it on the other.

Safety precautions to prevent the occurrence of a kickback or at least minimize its consequences for a person contains several simple rules:

  • It is unacceptable to use accessories not intended for the angle grinder:
  • a circle with a larger diameter, since to install it, you will have to remove the protective cover and, during use, there will be an excess of the linear speed of the cutting edge;
  • a saw blade completely unsuitable for the rotation speed of an angle grinder. a hard-alloy soldering that has flown off from his tooth at a cosmic speed can become a fatal bullet for a careless master.
  • The operator must stand firmly with both feet on a firm and level surface to resist the impact energy.
  • Be extremely careful when handling sharp edges, material edges, and any corners. It is necessary to be prepared for a possible kickback of the angle grinder and the body to move away from the intended place of defeat as a result of a return impact.
  • If the working disc is stuck, turn off the angle grinder and remove the cutting disc from the cut.

Safety precautions and understanding of the principles of working with an angle grinder guarantees high-quality performance of the tasks set without any injury or harm to human health.

  • You should not work with any power tool (not only with an angle grinder) being unhealthy, tired or in a state of alcoholic intoxication. the loss of clear control over the body leads to negligence in actions, lack of the required reaction speed and uncoordinated movements.
  • Indispensable components of safe work with an angle grinder are closed safety glasses (preferably reinforced) to reliably protect the eyes from the ingress of sparks or scale flying along an unpredictable trajectory, as well as a protective cover that ensures that no fragments of the processed material and sparks fall into the working material.
  • Always wear gloves or work gloves made of thick leather on your hands.
  • Work clothes should not be wide and at the same time should not restrict movement. Its parts should be carefully tucked in and no hanging or dangling elements: strings, fringes, etc., which could tighten under the moving disc of the instrument, should be avoided. When working with stony materials without organized stone dust extraction, a dust mask should be used to avoid respiratory problems.
  • The tool must be fully functional, do not use a deformed or damaged working disc, the use of which could cause kickback.

Which way should the sparks fly from the angle grinder

“Angle grinder”, as the craftsmen have long nicknamed the tool designed for cutting and grinding metals, stones and other materials, the angle grinder. The use of this tool is quite common both in construction and in agriculture and at home, for various kinds of domestic machinations. The car received such a name among the people because of the country of the manufacturer, as it is not difficult to guess Bulgaria.

Recently, the question “In which direction should the sparks fly from the angle grinder” has caused a real stir. And the fact is that people answer in different ways, and referring to their own personal experience. But if we talk not about experience, but about how to do it right.

Anatoly This is strictly individual, I prefer that the sparks fly to my feet, but if the angle grinder bites, it will jump out of me, and if it’s possible to drive a disc on my legs, I saw such a terrible sight.

Cut from yourself

When the angle grinder is set to rotate clockwise, cut the material away from you. If you cut on the contrary, the grinding machine will jam, this will damage the disc.

The main disadvantage of this method of work is that sparks and dust fly to the cutter. If they cut brick or concrete, wear a respirator, otherwise the airways will become clogged with dust. Clothes are carefully buttoned to reduce dust getting under the clothes.

When cutting metal, a sheaf of sparks flies towards the worker. This could cause the workwear to catch fire. The cuffs on the sleeves and the tops of the trousers are tightly tightened to prevent sparks from hitting the skin.

The main argument used by self-cutting advocates is safety. If the disc is bitten, the angle grinder pulls out in the opposite direction from the cutter, which means that the likelihood of injury decreases.

Important. To change the direction of rotation of the disc, turn the protective casing 180 degrees. Twist the handle into the hole on the back of the gearbox. Everything is carefully twisted and checked.

Safe place to work

Before starting cutting, prepare a place for work. They clean the site of debris so that nothing interferes with work. Flammable materials and combustible substances are removed from the site. Check the location for power cables.

The place is chosen with good natural light. If this is not possible, install lanterns or fluorescent lamps.

They work with an angle grinder only in dry weather, do not cut during rain or in rooms flooded with water.

During work, they remove jewelry, chains, key rings, objects that can get into the mechanism. So they don’t get wound around the disc.

At the construction site you need a class A, B or C fire extinguisher, it all depends on the place of work.

How to hold an angle grinder while working

The correct grip of the angle grinder will largely ensure competent and safe work with the tool:

  • The handles of the sander must be firmly gripped with both hands, without shifting its center of gravity to either one. With a secure grip, even in the event of a kickback, there will not be a serious displacement of the tool, and even more so it will not be pulled out of the hands.
  • The power cord must be kept away from the rotating blade: catching it will create a short circuit and a sudden stop of the tool, possibly resulting in kickback.
  • the cutting line should be positioned in such a way that the angle grinder goes to the master, moreover, the person should not be in the plane of the possible expansion of the disc. In this case, the direction of sparks is possible both away from the master and under him. everyone decides for himself. There are no options for left-handers. when you grip an angle grinder, the sparks will go “under yourself” in the only convenient way for a left-hander. And an obligatory rule. there should always be a bucket of water nearby to extinguish a fire possible from sparks.
  • It is forbidden to put the tool anywhere until the rotation of the working disc is completely stopped, otherwise objects and planes not intended for processing may be caught.
  • If you need to move the angle grinder from one place of work to another, you should turn it off, since any careless movement of the master (tripped, swayed, fell) can lead to unpleasant consequences: injuries, capture of foreign objects, clothes, etc.
  • The working disk heats up significantly during work, and, of course, you should not touch it until it cools completely.

Necessary security measures

The main thing when working with an angle grinder is safety. It does not matter which way the sparks fly, if the safety precautions are not followed, it will lead to serious injury.

Angle Grinder Precautions:

  • a safe place to work;
  • individual protection means
  • serviceable tool.
