The Fein MultiMaster Sanding Pad Kit is a must have for the owners of the MultiMaster! The 4- 1/2" diameter sanding pad from Fein is designed to maximize the 20,000 oscillations per minute of your Fein MultiMaster. German engineering provides an unrivaled sanding motion that yields one of the fastest and smoothest finishes when compared to any random orbital sander on the market. The 8-hole, hook and loop paper works in conjunction with the MultiMasters dust collection system and captures virtually all sanding dust when a vacuum is used.
