FAQ – Frequently Asked Questions About Flap Discs

Which flap disc is best suited for stainless steel?

For stainless steel and INOX, flap discs with zirconia alumina or ceramic grain are recommended, as they provide a clean grinding pattern without causing discoloration.

What is the difference between a flap disc and a grinding disc?

Flap discs consist of overlapping abrasive flaps. They allow for consistent material removal and leave a smoother surface than standard grinding discs.

Can flap discs be used on any angle grinder?

Yes. Flap discs with a 22.23 mm bore fit standard angle grinders (typically up to approx. 11,000 RPM). Always check the permissible speed of the disc.
