Osborn 0005607400 Power Tube Brush Helical Nylon 320 Grit

Product Description

The OSBORN 0005607400 is a helical power tube brush designed for cleaning, deburring, and finishing the interior surfaces of tubes, pipes, and bores. Built with nylon fill material impregnated with silicon carbide abrasive, this brush delivers consistent extra fine surface conditioning at 320 grit. The helical wire pattern ensures full contact along the bore wall for uniform abrasive action. With an overall length of 4 inches, a brush length of 1 inch, and a shank diameter of 0.046 inches, it mounts directly to a rotary tool or drill press for power-driven operation. Weighing 0.75 pounds, it is a compact, task-specific tool suited for maintenance and fabrication applications.

This tube brush is used in applications requiring light material removal or surface prep inside small-diameter tubes and ports. It is well suited for plumbing, HVAC coil tube maintenance, light industrial fabrication, and precision cleaning tasks where internal bore finish quality matters. The 0.105 inch brush diameter targets small-bore work where larger brushes cannot reach. Technicians in HVAC, plumbing, and general mechanical trades use this brush for tube prep before brazing, fitting, or inspection.

Key Features

• Helical brush configuration for consistent full-contact bore coverage
• Nylon fill with silicon carbide abrasive for extra fine surface conditioning
• 320 grit rating for controlled, light material removal and finishing

• 4 inch overall length with 1 inch brush length for reach into confined passages

Compatibility

Designed as an OEM-style power tube brush for use with rotary tools and drill presses accepting a 0.046 inch diameter shank, suitable for small-bore tube cleaning and surface conditioning tasks.

Installation Notes

Installation is performed by machinists, HVAC technicians, plumbers, or maintenance trades using a compatible rotary tool or drill press. Secure the shank firmly in the chuck before operation and confirm the tool is powered off before mounting or removing the brush. Always wear eye protection when operating abrasive rotary brushes, as silicon carbide particles and debris can be ejected at speed. Do not exceed the recommended RPM rating of the rotary tool for brushes of this diameter.
