Compared to many other power tools, the angle grinder is comparatively simple, being in essence a motor with a 90° drive at one end onto which a variety of different cutting, grinding or sanding discs can be attached. These machines are available in three sizes; 115,125 and 230mm but for most tasks on site, at home or in the workshop, the two smaller sizes are more than adequate. On the smaller machines, motor power is usually around 800W.
Angle grinders can produce a lot of debris and noise, so it’s recommended that suitable PPE is worn at all times.
Attach a wire wheel or brush onto the angle grinder and instantly you’ve created a very efficient method for removing paint and rust from flat, broad areas.
As an alternative to a wire brush a flexible backing pad can be fitted. This will accept Zirconium abrasive discs which offer very high performance, useful in situations requiring durability with high stock removal.
Cutting & Grinding
One of the most common applications of an angle grinder is to cut metal, though two different discs are required; one for grinding and another for cutting. There are also some diamond discs available that will cut metal as well as brick and masonry and these are probably the most useful of all the different sorts. With some care, a surprisingly delicate cut can be made on ceramic tiles which is particularly useful when trying to fit them round an existing toilet!
Pointing & Brickwork
Another useful accessory that will fit into an angle grinder is a diamond mortar rake. Re-pointing isn’t the most enjoyable of tasks, but it’s made slightly better when it becomes easier to remove the old mortar.
Carving & Shaping
An angle grinder can also be used very successfully for wood carving and sculpture. A special, heavy tct blade can be fitted to the machine which will remove a huge amount of material in a very short time. This makes it ideal when roughing out the depression in for example, a Windsor chair seat or any other sculptural application where a lot of wood needs to be swiftly removed. It’s particularly relevant with this type of blade that the correct protective equipment is worn when using it and safety guidelines are strictly followed.
