Weiler 91117 Helical Power Tube Brush Nylon 3/32 in Shank

Product Description

The WEILER 91117 is a helical power tube brush designed for cleaning, deburring, and surface preparation inside tubes, pipes, and bores. Fitted with a 3/32-inch shank diameter for chuck-driven power tools, this brush uses a single-spiral helical construction with nylon fill. The nylon bristles provide controlled abrasion suitable for softer base materials where wire fill would cause excess material removal or surface damage. Trades such as plumbing, HVAC, and general mechanical maintenance rely on this style of brush for consistent contact across the interior surface of a tube or fitting bore during prep work.

This tube brush suits applications in residential and light commercial settings where internal surface cleaning or deburring of tubing and pipe fittings is required. Typical install and service scenarios include cleaning copper pipe ends, removing light oxidation or deposits from tube interiors, and preparing bore surfaces before fitting or assembly. The nylon fill makes it appropriate for plastics, softer metals, and coated surfaces where aggressive abrasion must be avoided.

Key Features

• Helical single-spiral brush construction ensures full radial contact along tube interior walls
• Nylon fill material provides controlled, non-aggressive abrasion for softer substrates
• 3/32-inch shank diameter fits standard chuck-driven rotary power tools and drill presses
• Compact form factor suitable for small-diameter tube and bore applications
• Sold individually per package; minimum order quantity is 2 units

Compatibility

Designed as an OEM-style power tube brush for use with chuck-driven rotary tools accepting a 3/32-inch shank, suitable for small-bore tube and pipe cleaning applications across plumbing, HVAC, and general mechanical trades.

Installation Notes

Installation is performed by inserting the 3/32-inch shank into a compatible drill chuck or rotary tool and securing firmly before operation. Ensure the tool is at a full stop before inserting or removing the brush. Operate at speeds appropriate for nylon-fill brushes as specified by the tool manufacturer to avoid bristle deformation or premature wear. Eye protection and appropriate PPE should be worn during rotary brush use per standard shop safety practice.
