What You Need To Complete The Job

Use this 40 grit disc to remove material fast, then switch to the 80 grit and 120 grit discs for a smoother finish. Grinding throws sparks and grit, so add clear safety glasses and a pair of nitrile gloves. See the Power Tools range for grinders and accessories.

Frequently Asked Questions

What is a flap disc used for?

A flap disc combines grinding and finishing in one tool. The overlapping zirconia flaps wear down to expose fresh abrasive, so the disc keeps cutting as it works. It is used for stock removal, weld cleanup, blending and finishing on metal, and it fits straight onto an angle grinder without a backing pad.

When should I choose 40 grit?

Choose 40 grit when you want to remove material quickly, such as grinding down welds, taking off heavy scale or shaping a metal edge. It is a coarse grade, so it leaves a rougher surface. Follow it with an 80 or 120 grit disc if you need a smoother finish before painting or coating.

Does this disc fit a standard angle grinder?

Yes. The disc is 127mm in diameter with a 22mm bore, which suits the standard 125mm angle grinder spindle size. It mounts directly onto the grinder without a backing pad. Always check the maximum RPM rating on your grinder and use the correct guard.
