Osborn 0005644700 Power Tube Brush Helical Nylon 600 Grit

Product Description

The OSBORN 0005644700 is a helical power tube brush designed for internal bore cleaning, deburring, and surface conditioning of tubes and cylindrical passages. The brush uses nylon fill material loaded with aluminum oxide abrasive at a 600 grit super fine grade, making it suited for light material removal and fine surface finishing without aggressive stock loss. The 0.89 inch brush diameter reaches into small-bore tubing and fittings, while the 0.228 inch shank diameter accepts standard rotary tool chucks and power drivers. Machinists, pipe fitters, and maintenance technicians use this brush where a consistent, repeatable finish inside a tube or bore is required.

This brush is appropriate for light-duty finishing and cleaning applications in metal tubing, conduit ends, heat exchanger tubes, and similar cylindrical workpieces. The helical fill pattern promotes even abrasive contact along the bore wall during rotation. With a 1 inch brush length and 5 inch overall length, it fits into relatively deep passages while remaining manageable in a hand-held rotary tool or drill press setup. It is well suited for maintenance shops, fabrication environments, and field service situations where fine surface prep inside tubing is needed.

Installation Notes

This brush is installed and operated by a licensed machinist, pipe fitter, or trained maintenance technician using a rotary tool or drill rated for the brush RPM. Ensure the workpiece is securely fixtured and the rotary tool is at a full stop before inserting or removing the brush from the chuck. Wear appropriate eye protection and follow shop safety procedures when operating any rotary abrasive tool. Do not exceed the maximum rated RPM for the brush as marked by the manufacturer.
