Description:
Surface conditioning disc used for gasket removal, deburring, cleaning, and rust removal. Use instead of wire brushes or sand paper when you don't want to remove any stock.
Uses a more positive retention method than the "hook and loop" fastener system
R-style discs have a quarter turn male fastener embedded into the disc. The disc holder has the corresponding female fastener.
Typically used at smaller sizes where the higher maximum operating speed requires a more positive retention system
The disadvantage of this system is that the surface conditioning operation must always be conducted in one direction only. Reversing the tool will "unspin" the disc from the holder.
