Weiler 26908 Power Tube Brush 0.19 in Helical Nylon

Product Description

The WEILER 26908 is a helical power tube brush designed for cleaning, deburring, and surface preparation inside small-diameter tubes, ports, and bores. It uses a single-spiral nylon fill with aluminum oxide abrasive at 600 grit, making it suited for ultra-fine finishing work where aggressive material removal would cause damage. The brush measures 0.19 inches in diameter with a 1-inch brush length and an overall assembly length of 5 inches. The galvanized steel shank measures 0.087 inches in diameter and is rated for power tool use up to 2000 RPM. Machinists, maintenance technicians, and fabricators typically reach for this brush when working with precision tubing or tight internal geometries.

This brush is used in applications requiring controlled interior surface finishing in small-bore components. It is well suited for tube cleaning, port preparation, and light deburring in metalworking, maintenance, and light industrial environments. The nylon fill with aluminum oxide abrasive at 600 grit handles delicate surfaces where metal wire fill would leave unwanted scratches or dimensional changes. The helical single-spiral construction ensures even contact along the bore wall during rotation.

Installation Notes

Install and remove the brush only while the tool is powered off and fully stopped. Confirm the tool chuck or collet is rated for the 0.087-inch shank size before mounting. Do not exceed 2000 RPM during operation. Eye protection and appropriate PPE should be worn whenever operating abrasive rotary brushes.
