Pro-source 05077 Brass Twisted Wire Bristle Brush 9/16 in

Product Description

The PRO-SOURCE 05077 is a single-spiral brass twisted wire bristle brush designed for cleaning, deburring, and surface preparation in tight or threaded passages. The brush head measures 0.5625 inches in diameter and 2.5 inches in length, while the full assembly reaches 9 inches overall, giving technicians adequate reach into ports, tubes, and fittings without risking contact with hands or adjacent components. The 0.008-inch brass wire filaments flex without scratching softer base metals, making this tool a practical choice for copper pipe prep, valve seat cleaning, and bore maintenance. The galvanized steel shank measures 0.142 inches in diameter and mounts directly into a standard drill or rotary tool chuck.

This brush is commonly used in plumbing, HVAC, and general mechanical service work where internal surfaces need to be cleaned before fitting, soldering, or inspection. Typical applications include cleaning inside pipe ends, removing light oxidation from copper tubing, clearing debris from valve bodies, and prepping threaded bores. The single-spiral fill pattern provides consistent contact around the full bore circumference. It is well suited for use by plumbers, HVAC technicians, and mechanical tradespeople who need a small-diameter rotary brush for detail cleaning tasks on the bench or in the field.

Key Features

• Brass wire fill resists corrosion and will not contaminate copper or soft-metal surfaces
• Single-spiral construction delivers even filament distribution around the full brush diameter
• 9-inch overall length provides reach into recessed ports and fittings
• 0.142-inch galvanized steel shank fits standard rotary tool and drill chucks
• 0.008-inch wire diameter provides firm but flexible scrubbing action without aggressive material removal

Compatibility

Designed as a general-purpose rotary bristle brush for use with standard drill chucks and rotary tools that accept a 0.142-inch round shank.

Installation Notes

This brush is installed into a drill or rotary tool chuck by a plumber, HVAC technician, or mechanic. Confirm the chuck opening accommodates the 0.142-inch shank diameter before use. Operate at a speed appropriate for the material being cleaned and wear eye protection, as wire bristles can shed under load. Inspect the brush for damaged or splayed filaments before each use and replace if wear is evident.
