3M 7100138298 Radial Bristle Brush 6in Type 120

Product Description

The 3M 7100138298 is a Scotch-Brite Radial Bristle Brush designed for surface preparation, blending, deburring, and finishing on metal and other materials. The brush measures 6 inches in diameter, 7/16 inches in arbor hole size, and 1 inch in face width. Rated at Type 120, it delivers a finer cut suited to light deburring and surface conditioning tasks. It is used by HVAC technicians, pipefitters, electricians, and general trade professionals who require consistent, repeatable surface finishing without aggressive material removal.

This radial bristle brush is well suited for use on copper tubing, aluminum, steel, and other metal surfaces common in HVAC, plumbing, and electrical trade work. It performs reliably in both bench-mounted and handheld rotary tool setups where controlled surface preparation is needed before brazing, soldering, or coating. The brush is sold individually and is compatible with the included adapter for standard arbor mounting.
