Cool-Sanding Backup Pads for Arbor-Mount Sanding Discs
These pads are designed to channel air flow to the sanding disc for cooler operation, prolonging the life of the disc. Install the backup pad onto the tool’s arbor, then attach a sanding disc and secure with a disc nut.
Style A comes with a separate plate which has a hole pattern to allow air flow.
Style B have spiral ribs which form air-flow channels. Disc nuts are sold separately.

The threaded spindles on these grinders accept raised-hub grinding wheels. Grinders have a spindle lock for fast wheel changes and a side handle.
Grinders that meet OSHA 29 CFR 1910.215 and OSHA 29 CFR 1926.303 are compliant with standards for abrasive wheels. Grinders that meet OSHA 29 CFR 1910.243 are compliant with standards for hand-held equipment.
Wheel guards are required when using grinding wheels and cups.
Backup pads are required when using sanding discs. Thread the backup pad onto the tool's arbor, then attach a sanding disc and secure with its disc nut.
Match replacement parts to the manufacturer, model number, and type of your grinder, all of which are listed on the tool's label.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
