Tru-maxx 88522 End Brush 1 in Stainless Steel Crimped Wire

Product Description

The TRU-MAXX 88522 is a 1-inch diameter end brush designed for use with rotary tools, die grinders, and power drills. It features crimped stainless steel wire fill and is rated to a maximum of 22,000 RPM. The flared wire construction allows for consistent contact pressure across irregular surfaces. With a 3/4-inch steel shank included, this brush mounts directly into standard collets and chucks without adapters. It is used primarily for deburring, surface preparation, weld cleanup, and light material removal on metal workpieces. The crimped wire provides moderate aggressiveness suitable for finishing and blending tasks.

This end brush is suited for metal fabrication shops, maintenance and repair operations, and plumbing or HVAC installations where pipe ends, fittings, or weld beads require cleaning and surface prep before assembly or inspection. The stainless steel fill resists corrosion and contamination, making it appropriate for use on stainless steel base materials where carbon steel wire could cause surface contamination. It is a single-unit package intended for bench or handheld power tool use.

Installation Notes

Installation is performed by trade professionals including pipefitters, welders, HVAC technicians, and general maintenance mechanics. Always power down and disconnect the tool from its power source before inserting or removing the brush shank from the collet or chuck. Confirm the tool spindle RPM rating meets or exceeds the 22,000 RPM maximum before use. Wear appropriate eye and face protection during operation as wire bristles can shed at speed.
