Norton 66252838860 Cup Brush 2.25in Carbon Steel Crimped

Product Description

The NORTON 66252838860 is a crimped-wire cup brush designed for surface preparation, deburring, cleaning, and blending on metal workpieces. The brush measures 2.25 inches in diameter with a 1/4-inch shank arbor for use in standard die grinders and drill motors. Wire diameter is 0.014 inches, made from carbon steel, providing moderate aggression suitable for rust removal, weld spatter cleanup, and light scale removal. Trim length is 0.625 inches. Maximum rated speed is 4,500 RPM. This type of abrasive accessory is handled by metalworkers, maintenance technicians, fabricators, and general industrial tradespeople.

This cup brush suits light to medium surface preparation tasks on ferrous metals in industrial, maintenance, and fabrication settings. The crimped wire construction delivers a slightly flexible action that conforms to irregular surfaces and contours, making it practical for cleaning pipe ends, weld joints, castings, and structural steel components. The 1/4-inch shank allows direct mounting in most pneumatic die grinders or electric rotary tools without adapters.
