Product Description

The 3M 7000046182 is a radial bristle brush designed for surface preparation, deburring, and finishing on metal and hard materials. The brush features ceramic abrasive bristles rated at 360 grit, making it suitable for fine finishing and light material removal. It measures 3 inches in outside diameter with a 3/8-inch thickness and fits a 3/8-inch arbor connection via a plain arbor hole. Rated to a maximum of 20,000 RPM, this brush is built for use with die grinders, rotary tools, and similar high-speed equipment. HVAC techs, plumbers, and metalworkers commonly use this type of brush for tube end prep and weld cleanup.

This radial bristle brush is used in residential and commercial trade applications where controlled surface conditioning is required. Typical tasks include deburring pipe ends, cleaning weld beads, removing light oxidation, and prepping mating surfaces before assembly. The green color identifies the 360-grit ceramic grade, which delivers consistent cut rates on steel, stainless, aluminum, and copper. Its compact 3-inch diameter allows access to tight spaces and fits standard die grinder mandrels without modification.
