Angle grinders are used in most home and commercial workshops because they are one of the most versatile tools. By simply changing the angle grinder grinding wheel, you can perform a range of tasks quickly and easily, such as cutting metal, removing rust and paint, deburring, preparing metal for welding, scribing and cutting stone, tiles and concrete, and cutting off mortar.
For small or infrequent work, a angle grinder grinding wheel can be used on the drill and supported by a liner. For conventional or heavy duty applications, angle grinder grinding wheel or angle grinders will provide the best results.
Tips for cutting metal using angle grinders, angle grinder grinding wheel and rotary tools.
The angle grinder grinding wheel rotates very fast, which causes the hot sparks and chips to fly quickly. To protect your safety, goggles, heavy duty work gloves, protective footwear and ear protectors are recommended.
First select the angle grinder grinding wheel that best suits your project, then check that the maximum rpm of the angle grinder grinding wheel is higher than the maximum rpm of the tool; this will prevent the angle grinder grinding wheel from being overstressed and broken, resulting in serious injury.
The angle grinder grinding wheel has two forms: a flat surface, a convex center, and a concave center. The raised and lowered center angle grinder grinding wheels are well suited for entering narrow corners and cantilever because they allow access to the metal at different angles. Do not drive these angle grinder grinding wheels too deeply, as the changed angle grinder grinding wheel geometry may block and damage the angle grinder grinding wheel.
Recommended angle grinder grinding wheel type.
Angle grinder grinding wheel type/ use
Metal cutting piece / cutting piece
Cut most metals. Do not use for grinding. At a 90 degree angle to the workpiece
The cutting edge consists of alumina
Angle grinder grinding wheel
Grinding ferrous and non-ferrous metals. At a 45 degree angle to the workpiece.
The cutting edge consists of alumina
Multi-knife angle grinder grinding wheel
Cut through ferrous and non-ferrous metals (including stainless steel). It will also cut through bricks, stones, modern composites and tiles to meet more complex cutting requirements.
Stainless steel angle grinder grinding wheel
Cutting steel and stainless steel. Particularly useful for small cross sections.
Full cut diamond blade
Cut through cast iron, other black and non-ferrous metals and most building materials
The diamond particles are bonded to the cutting edge.
Gravel mop tray
General grinding of metals, especially for edge grinding projects such as deburring, sharpening and surface finishing.
A angle grinder grinding wheel that is radially arranged in a fan shape.
Slitting disc / thin cutting angle grinder grinding wheel
Cutting thin-walled profiles and pipes. Provide a thin line. Suitable for ferrous and non-ferrous metals as well as stainless steel.
Thin angle grinder grinding wheels generate less heat during operation, produce less tool vibration, complete cutting in less time, and waste less metal per cut, saving up to 2mm per cut .
Firmly clamp the workpiece near the desired cutting point or ensure that the workpiece cut from it is strong and does not fall during operation.
Run the grinder for about a minute to check that the cutting tools and angle grinder grinding wheels are installed correctly to ensure that any balance or installation problems are found before starting work.
When starting to cut, always place the blade at a 90-degree angle to the workpiece, taking care to ensure that the shield is between the worker and the workpiece. Avoid impact or impact on the metal sheet, and always place the cutting blade in the thinnest part of the metal. Because the surface contact is uniform, it is the easiest to process the circular contour. For example, the “I-beam” and the box section should be contoured from the corner. Start. Reduce friction. Don’t put too much pressure on it, just let the angle grinder grinding wheel get the job done.
If needed, it is useful to use a ground trowel after corner grinding to deburr and smooth the burrs.
