Norton 66252838859 Stainless Steel Crimped Cup Brush 2 in

Product Description

The NORTON 66252838859 is a crimped cup brush designed for surface preparation, weld cleaning, and light deburring tasks on metal workpieces. Constructed with stainless steel fill wire at 0.01 inches in diameter, it delivers consistent abrasive action without contaminating stainless or aluminum base materials. The cup-style configuration concentrates wire contact on a focused work area, making it effective for blending, descaling, and removing oxidation. Rated to 10,500 RPM maximum, it is compatible with standard die grinders and small angle grinders fitted with a 1/4-inch shank arbor. Metalworkers, fabricators, and maintenance technicians are the primary users of this tool.

This cup brush is suited for bench or handheld power tool use in fabrication shops, field maintenance, and light industrial environments. It handles tasks such as pre-weld joint cleaning, post-weld spatter removal, and surface conditioning on ferrous and non-ferrous metals. The 5/8-inch trim length provides moderate stiffness for controlled material removal without excessive wire deflection. Its compact 2-inch diameter allows access to confined areas, weld joints, and tight corners where larger brushes cannot reach.

Key Features

• Stainless steel fill wire resists corrosion and prevents cross-contamination on stainless steel or aluminum surfaces
• Crimped wire construction provides consistent, flexible contact across irregular surface profiles
• 2-inch brush diameter targets confined areas and tight weld joints
• 10,500 RPM maximum speed rating for use with standard die grinders
• 1/4-inch shank arbor fits common die grinder and rotary tool chucks
• 5/8-inch trim length balances wire stiffness and surface coverage

Compatibility

Designed for use with die grinders and rotary tools equipped with a 1/4-inch shank chuck. Confirm the tool spindle speed does not exceed 10,500 RPM before use.

Installation Notes

Installation is performed by qualified metalworkers or maintenance technicians using a die grinder or compatible rotary tool. Ensure the tool is unplugged or the air supply is disconnected before mounting the brush onto the 1/4-inch shank. Verify the tool RPM rating meets or does not exceed the 10,500 RPM maximum stamped on the brush. Always wear appropriate eye protection and follow applicable ANSI B11 or OSHA 29 CFR 1910.243 safety standards when operating wire brushes on power tools.
