Its versatility makes it a useful tool for grinding, sanding, cutting, polishing, and more. Its uses are limited only by the user's imagination and the available attachments.

1.Cleaning metals by removing rust: An angle grinder equipped with the right attachment is ideal for removing old paint and rust from metal surfaces without damaging the underlying paint. This tool is handy for cleaning metal pipes or garden furniture. Angle grinder discs made from corrosion-resistant ceramic called silicon carbide are an effective solution for removing rust and paint. These circular scouring pads are specially designed for this purpose.

2.Cutting down metal as per usage: By replacing a grinding disc with a cutting disc, an angle grinder can effortlessly cut through metal, making it a popular choice in home renovation projects. It is particularly useful when working with galvanized steel pipes, sheet metal, or shortening metal fixtures. It is better to use a pipe cutter instead of an angle grinder when cutting copper pipes. This is because a pipe cutter provides a cleaner cut, which is important for later soldering. If an angle grinder is used, extra work may be needed to smooth and straighten the edges of the copper pipe.

Therefore, it is appropriate to consult professionals or seek guidance from the instruction manual to avoid damaging the instrument.

5.Cutting down the tiles: Cutting small sections and finer details on tiles can be challenging, but an angle grinder, particularly a small one, provides an excellent way to cut with precision. An angle grinder lets you cut details and make holes larger than those drilled into tiles easily. Using the appropriate cutting disc is crucial when cutting natural stone, porcelain, and ceramic tiles. Diamond-tipped blades are best for ceramic tiles, while notched blades are ideal for porcelain tiles. Serrated blades are recommended for natural stone.

6.Removes mortar between the bricks: You can use an angle grinder with a mortar raking blade to remove mortar between bricks. These blades are segmented and resemble a flower head with petals. They are specifically designed for this task and are commonly called mortar raking blades. Removing mortar without harming brick is a simple task with the right blade attachment, enabling the repointing of brickwork with fresh mortar for a renewed appearance.
