40 x 20mm Flap Wheel — 6mm Shank, Abracs Spindle Mounted

Abracs 40 x 20mm spindle mounted flap wheel on a 6mm shank, for deburring, blending and finishing in a drill or die grinder. A step up in reach and coverage from the 25mm while still working comfortably into corners and recesses. Overlapping abrasive flaps flex to follow the contour of the workpiece rather than flattening it, and wear away as you go to keep exposing fresh grit.

This is not an angle grinder disc
Spindle mounted flap wheels fit a drill or die grinder chuck. If you are after a flap disc for an angle grinder, see our zirconium flap discs instead.
