Osborn 0005644400 Power Tube Brush Helical Nylon 600 Grit

Product Description

The OSBORN 0005644400 is a helical power tube brush designed for cleaning, deburring, and surface finishing inside tubes, pipes, and bores. The brush features a 0.765-inch brush diameter and a 0.228-inch shank diameter, making it compatible with standard rotary tools, drill presses, and power screwdrivers. Fill material is nylon impregnated with aluminum oxide abrasive at a 600 grit, super fine grade. With a 1-inch brush length and a 5-inch overall length, this tool delivers controlled, consistent contact inside confined cylindrical passages. It is commonly used by HVAC technicians, plumbers, pipefitters, and maintenance professionals for tube prep and bore cleaning tasks.

This power tube brush is suited for light deburring, surface conditioning, and cleaning of tube interiors in both residential and commercial service environments. Typical applications include heat exchanger tube cleaning, copper pipe prep, and bore finishing on ferrous and non-ferrous materials. The helical wrap pattern promotes even abrasive contact along the full brush length during rotation. It is packaged individually and is appropriate for bench or handheld power tool use.
