3M 7000121795 | 711429 Standard Abrasives 1/2" Diameter x 1/4" Shank x 1/2" OAL Rubber Sanding Drum

The Standard Abrasives Rubber Sanding Drum holds an abrasive band for contour work (band sold separately). Constructed from rubber, the drum expands at high speed for the closest possible fit with a band of the same size for controlled operation. This enables it to run smoothly over contoured surfaces and into hard-to-reach areas without skipping or jumping for a smooth, precise finish.

When balanced handling is essential and an abrasive belt won't fit the part, a good solution is to use a Standard Abrasives Rubber Sanding Drum fitted with a Standard Abrasives Spiral Band (sold separately). The spiral band can be a coated abrasive for polishing and blending, a non-woven surface conditioning product for effective finishing. In either case, the Standard Abrasives Rubber Sanding Drum offers an even application on contours and hard-to-reach areas with a rotary tool.

It is important for both the drum and the abrasive to have the same nominal diameter to prevent skipping and bumping. Rather than deflecting or skidding over the substrate, the spiral band stays in constant contact with the workpiece to swiftly rid the surface of little burrs. The maximum allowable RPM for spiral bands is the same as the maximum RPM of the drum, provided the drum and band have the same nominal diameter. Typically, the rubber drum attaches to portable drills, die grinders, straight shaft and angle grinders. The great news is, the drum requires no extra tools for band changes.

The Standard Abrasives brand has supplied quality abrasives to the metalworking industry for over 50 years. Customers rely on the broad offering of high performance products including coated, bonded, non-woven abrasive lines.
