Using An Angle Grinder
The first thing you need to do before using your angle grinder is to ensure you are fully protected. PPE gear such as safety glasses will help protect you from any flying sparks. Hearing is also essential along with safety footwear and clothing. Set the angle grinder to the preferred side you wish to use and rotate the safety guard so it matches your position. Clamp your workpiece in place on your work surface to make sure it doesn’t slip while you work on it. Switch on the angle grinder and let it build up to its maximum speed. Apply the angle grinder to the workpiece without pushing it, and slowly move it back and forth along the line you wish to cut.
Angle Grinder Components
The type of disc used in an angle grinder allows it to perform a range of functions. Some disc types used with angle grinders include:
- Angle grinder discs – The most common disc used in basic grinding. These come in different sizes and grit numbers depending on the coarseness of the material being ground.
- Cut-off discs – Used for cutting metal objects such as bars and sheets. These are generally thinner than angle grinding discs and made from harder materials.
- Flexible grinding / flap discs – Similar to grinding discs, these discs are used for polishing and finishing a workpiece. The higher the grit number, the smoother the disc.
- Wire brush grinding wheels – These consist of a set of wires attached to a circular base. They are mainly used for removing rust and paint from surfaces to ensure a clean surface.
- Diamond cutting discs – These wheels have diamonds fixed to the surface as well as a cutting rim. They are used to cut harder materials such as granite.
- Polishing pads – To make any surface look shiny and new, polishing pads come in a variety of shapes and sizes.
