Weiler 98357 Helical Power Tube Brush Steel 7/32 Inch

Product Description

The WEILER 98357 is a helical power tube brush designed for rotary-tool applications requiring aggressive tube, bore, and pipe cleaning. Built with a steel fill and a double-spiral construction, this brush delivers consistent scrubbing action along the full length of tubing interiors. The 7/32 inch shank diameter fits standard rotary tool chucks and power-tool adapters used in HVAC, plumbing, and light fabrication work. At 0.05 pounds, it is a compact, single-piece consumable intended for detailed deburring, surface prep, and deposit removal inside small-diameter tubing.

This brush is suited for trade applications where internal bore prep is required before fitting assembly, soldering, or inspection. HVAC technicians and plumbers reach for this type of brush to clean tube ends and fittings prior to brazing or press connections. It is also used in light industrial and fabrication settings for deburring drilled holes and cleaning threaded bores. Sold as a single-piece unit, it is a practical addition to a service kit for field or bench use.

Wear appropriate eye protection when operating rotary brushes at speed. Inspect the brush fill for wear or wire fatigue before each use and replace if wires are frayed or missing.
