An angle grinder, also known as a side grinder or disc grinder, is a handheld power tool that can perform a variety of tasks, such as cutting, grinding, polishing, and sanding different materials. Angle grinders are widely used in metalworking, construction, woodworking, and automotive industries. But what is the main use of angle grinder?

The main use of angle grinder is to cut metal. Angle grinders can cut through various types of metal, such as steel, aluminum, copper, and iron, with ease and precision. Angle grinders can also cut other materials, such as concrete, stone, brick, tile, and plastic, depending on the type of disc used. Angle grinders are versatile tools that can handle different cutting jobs with speed and efficiency.

How to use an angle grinder to cut metal

To use an angle grinder to cut metal, you need to follow some basic steps and safety precautions. Here are some tips on how to use an angle grinder to cut metal:

Choose the right disc for the job. There are different types of discs for angle grinders, such as abrasive discs, diamond discs, and metal cut-off discs. Abrasive discs are suitable for general cutting and grinding, but they wear out quickly and create sparks. Diamond discs are more durable and can cut through hard materials, such as concrete and stone, but they are more expensive and require water cooling. Metal cut-off discs are designed specifically for cutting metal, and they are thin and sharp, but they can shatter easily and generate a lot of heat. You should choose the disc that matches the material and the thickness of the metal you want to cut.

Attach the disc to the angle grinder. Make sure the disc is compatible with the size and speed of your angle grinder. Also, make sure the disc is securely fastened and aligned with the spindle. You can use a wrench or a spanner to tighten the disc nut. Do not over-tighten the disc, as it may damage the disc or the angle grinder.

Mark the metal where you want to cut. You can use a marker, a chalk, or a tape to mark the metal where you want to cut. This will help you guide the angle grinder along the line and make a straight and accurate cut. You can also use a clamp or a vise to hold the metal in place and prevent it from moving while you cut.

Wear protective gear. Cutting metal with an angle grinder can be dangerous, as it can produce sparks, flying debris, noise, and heat. You should wear protective gear, such as gloves, goggles, ear plugs, and a dust mask, to protect yourself from injuries. You should also wear long sleeves, pants, and shoes, to cover your skin and avoid burns. You should also keep flammable materials, such as paper, cloth, and gas, away from the cutting area, as they may catch fire from the sparks.

Plug in the angle grinder and turn it on. You should plug in the angle grinder to a power source and turn it on. You should hold the angle grinder with both hands, and keep the disc away from your body. You should also check the direction of the disc rotation, and make sure it is spinning away from the edge of the metal you want to cut. This will prevent the disc from kicking back and hurting you.

Cut the metal with the angle grinder. You should slowly lower the disc to the metal and apply a gentle pressure. You should not force the disc into the metal, as it may cause the disc to overheat, warp, or break. You should also move the angle grinder along the marked line, and keep the disc perpendicular to the metal. You should not twist or tilt the angle grinder, as it may cause the disc to bind or jam. You should also pause the angle grinder every few seconds, and let the disc cool down. You should also clear the metal shavings and dust from the cutting area, and avoid touching the metal or the disc, as they may be hot.

You should also let the disc stop spinning completely, and remove it from the angle grinder. You should also inspect the disc for any cracks or damage, and replace it if necessary. You should also clean the angle grinder and the disc, and store them in a dry and safe place.
