Product Description

The 3M 7100138299 is a Scotch-Brite Radial Bristle Brush designed for surface conditioning, deburring, blending, and finishing on metal and other hard materials. The brush measures 6 inches in diameter with a 7/16-inch arbor hole and a 1-inch brush width. The 220-grit rating makes it well suited for fine finishing and light surface prep work. It mounts to a compatible adapter and installs on a right-angle grinder or bench-mounted spindle. Trade professionals use it for weld blending, pipe end preparation, and general surface cleanup in HVAC, plumbing, and mechanical fabrication contexts.

This radial bristle brush is appropriate for use in both residential and light commercial service applications where consistent, controlled surface finishing is required. The bristle design conforms to irregular surfaces and contours, making it practical for cleaning fittings, tubing ends, and fabricated metal components. It is sold individually, with a minimum order quantity of 5 units per transaction.
