Pro-source 04982 Brass Twisted Wire Bristle Brush

Product Description

The PRO-SOURCE 04982 is a single-spiral brass twisted wire bristle brush designed for detail cleaning, deburring, and surface prep in tight-clearance applications. The brush head measures 0.5 inches long and 0.0625 inches in diameter, with individual brass wire filaments at 0.003 inches in diameter for effective scrubbing without aggressive abrasion. Overall length is 4 inches, and the stainless steel shank measures 0.032 inches in diameter for secure chuck or collet mounting. This brush is well suited to bench work, machine shop cleanup, and tube or port cleaning tasks performed by machinists, HVAC technicians, and plumbers who need a small, precise brush for bore and fitting preparation.

This brush is used in applications requiring a compact, flexible cleaning tool that can reach narrow bores, ports, fittings, and small orifices. The brass fill material is non-sparking and compatible with soft metals and coated surfaces where steel bristles would cause damage or contamination. Common applications include cleaning refrigerant line fittings, small valve seats, instrument ports, and threaded bores in light manufacturing and field service environments. The 4-inch overall length provides enough reach for most bench and in-place cleaning tasks.

Key Features

• Brass fill material is non-sparking and safe on soft metal and coated surfaces
• Single-spiral construction delivers consistent bristle contact through the full brush length

Compatibility

Designed as a standard small-diameter twisted wire bristle brush for use with rotary tools, flex shafts, and drill chucks that accept a 0.032-inch shank diameter.

Installation Notes

Secure the shank fully into the chuck or collet of the rotary tool before operation to prevent slippage or runout. Verify that the rotary tool RPM rating is appropriate for a brush of this diameter before running at speed. Inspect the bristle fill before each use and replace the brush if wires are bent back, missing, or show signs of fatigue. Use eye protection whenever operating rotary wire brushes.
