Osborn 0005641200 Power Tube Brush 0.105 in Helical Nylon

Product Description

The OSBORN 0005641200 is a helical power tube brush designed for cleaning, deburring, and surface preparation inside tubes, pipes, and bores. Fitted with a 0.046-inch diameter shank for chuck or drill attachment, it carries a nylon fill loaded with alumina silicate abrasive at a 1000 grit ultra-fine grade. The brush head measures 0.105 inches in diameter with a 1-inch brush length and a 4-inch overall length. Machinists, maintenance technicians, and HVAC or plumbing tradespeople use this tool when a light, non-aggressive cutting action is needed to clean or finish small-diameter internal surfaces without damaging base material.

This brush is suited for use on small-bore tubing, heat exchanger tubes, condenser tubes, and similar internal passages where access is tight and aggressive wire brushing would cause surface damage. The helical fill pattern distributes abrasive contact evenly along the bore wall, making it appropriate for both rotary drill applications and low-speed power tools. Its ultra-fine alumina silicate nylon construction works on metal, plastic, and composite internal surfaces.

Key Features

• Helical fill pattern for even, consistent bore-wall contact
• Nylon fill with alumina silicate abrasive for gentle, ultra-fine surface action
• 1000 grit ultra-fine grade minimizes material removal on sensitive surfaces
• 0.046-inch shank diameter fits standard drill chucks and rotary tools
• Compact 4-inch overall length suits tight-access applications

Compatibility

Designed as a general-purpose helical tube brush for small-bore cleaning and finishing applications where a 0.105-inch brush diameter and 0.046-inch shank are the required fit.

Installation Notes

Install the shank securely in a drill chuck or compatible rotary tool before operation. Ensure the work piece or system is fully de-energized and depressurized before inserting the brush into any live tube or pipe assembly. Match rotation speed to the brush and substrate material specifications to avoid premature wear or fill damage. Discard the brush if fill material shows significant deformation or loss.
