Osborn 0003508700 Flat Steel Power Tube Brush

Product Description

The OSBORN 0003508700 is a flat-style power tube brush designed for mechanical cleaning of tubes, pipes, and bore openings. Constructed with steel fill, it delivers aggressive scrubbing action suited for removing scale, corrosion, and deposits from metal surfaces. The 1/8 inch shank diameter allows it to chuck directly into standard rotary tools, drill motors, and flexible shaft machines. HVAC technicians, plumbers, and pipe fitters reach for this brush when prepping tube interiors before brazing, soldering, or inspection. The flat brush profile conforms to tube walls to maximize contact and cleaning efficiency on each pass.

This brush is suited for light industrial and trade applications where tube bore cleaning is part of routine service or installation prep. Typical use cases include cleaning heat exchanger tubes, condenser tubes, copper pipe ends, and similar small-diameter bores. Its steel fill makes it appropriate for ferrous and non-ferrous metal surfaces that require mechanical abrasion rather than softer nylon or brass bristle action. The 1/8 inch shank keeps it compatible with commonly available rotary tooling found on most service vehicles.

Key Features

• Flat brush profile maximizes contact with tube bore walls during rotation
• Steel fill provides aggressive cleaning action for scale, rust, and deposits
• 1/8 inch shank diameter fits standard rotary tools and drill chucks

Compatibility

Designed for use with rotary tools, drill motors, and flexible shaft machines accepting a 1/8 inch round shank. Suitable for cleaning small-diameter tube and pipe bores in HVAC, plumbing, and general mechanical service applications.

Installation Notes

This brush is installed by inserting the 1/8 inch shank into the chuck of a compatible rotary tool or drill and tightening securely before operation. Always wear appropriate eye protection when operating power brushes, as wire bristles can shed under load. Verify the tool RPM rating does not exceed the brush manufacturer maximum before use. Isolate and de-energize any system being serviced before accessing tube interiors.
