The level of hardness needed is dependent on the task—choose a higher density for more aggressive applications and a lower, more flexible density for less aggressive applications—and is also dependent on the user’s work style. We designed these disc pads to be used with any drill, disc sander, right angle grinder, or rotary sander. Max RPM is determined by size and firmness of the disc and disc pad.

Our 3M™ Roloc™ Disc Pad is available for use with the following Roloc attachment systems: TR, TP and TS. Please select discs with the attachment design made for your system.
