115mm Backing Pad (M14) — For Fibre Sanding Discs, Angle Grinder

115mm backing pad for mounting fibre sanding discs on an angle grinder — the most common size, to match a standard 4.5 inch grinder. A fibre disc is flat and needs a pad behind it: this pad screws onto the grinder spindle with an M14 thread and gives the disc the firm, flexible support it needs to cut evenly and last. Made from a premium nylon compound for flexibility and long life.

Fibre disc pad, not an orbital sander pad
This is a threaded M14 pad for an angle grinder, for use with fibre sanding discs. It is not a hook and loop pad for a DA orbital sander. If you need a pad for hook and loop or self-adhesive discs, see our other backing pads.

Fits
Any angle grinder with an M14 spindle. Use a 115mm pad with 115mm discs so the disc slightly overhangs the pad edge, which protects the pad rim from wear.
