Value Collection 3103806320 Cup Brush Brass Crimped

Product Description

The VALUE COLLECTION 3103806320 is a crimped-wire cup brush designed for surface preparation, cleaning, deburring, and light rust or scale removal on metal and other hard surfaces. The brush measures 1.75 inches in diameter and uses brass wire at 0.008 inches in diameter, making it well suited for applications where a softer, non-sparking abrasive is needed. It mounts via a 1/4-inch straight shank, allowing it to be chucked directly into a drill press or handheld power drill. With a maximum rated speed of 13,000 RPM, it delivers consistent results across a range of rotary tools. Licensed tradespeople and maintenance technicians working in HVAC, plumbing, electrical, and general mechanical fields regularly use this style of brush for tube cleaning, terminal prep, and weld seam cleanup.

This cup brush is suited for use on copper pipe ends, electrical terminals, threaded fittings, and other surfaces requiring controlled abrasive action without introducing ferrous contamination. The brass fill material makes it a practical choice for work on softer alloys, non-ferrous metals, and plated surfaces where steel wire could cause damage or embed unwanted particles. Its compact 1.75-inch diameter fits into confined areas on equipment panels, pipe assemblies, and junction boxes. The 9/16-inch trim length provides moderate stiffness for controlled material removal.

Key Features

• Crimped brass wire fill for non-sparking, non-ferrous surface preparation
• 1.75-inch brush diameter suited for confined-area access
• 0.008-inch wire diameter balances flexibility with cleaning aggressiveness
• 1/4-inch straight shank fits standard drill chucks and rotary tools
• 9/16-inch trim length provides controlled stiffness during use
• Rated to 13,000 RPM for compatibility with common handheld drills and drill presses

Compatibility

Designed for use with power drills, drill presses, and rotary tools accepting a 1/4-inch straight shank. Suitable for non-ferrous metal surfaces, copper tubing, brass fittings, and plated components where a non-sparking abrasive wire is required.

Installation Notes

Installation is performed by a technician or qualified tradesperson using any drill or rotary tool with a compatible 1/4-inch chuck. Ensure the tool is powered off and the chuck is fully tightened before operating the brush. Always verify the tool's rated RPM does not exceed the brush's 13,000 RPM maximum before use. Eye protection and appropriate PPE should be worn during operation, as wire bristles can fatigue and separate at high speeds.
