Precision Internal Cleaning with Weiler Power Tube Brushes

The Weiler 21082 3/8" Power Tube Brush is a high-performance abrasive tool engineered for the demanding requirements of the aerospace, automotive, and manufacturing industries. Designed specifically for cleaning and deburring smooth or threaded blind holes, this brush features a single continuous length of stainless steel stem wire. This construction method significantly enhances the structural integrity of the brush, reducing the risk of stem failure during operation and ensuring consistent performance over a longer service life.

Equipped with a single spiral of crimped .004" stainless steel wire fill, the brush delivers a flexible brushing action that effectively conforms to internal geometries without altering the dimensions of the part. The use of stainless steel fill is critical for applications involving stainless steel, aluminum, titanium, and high-nickel alloys, as it prevents the risk of ferrous contamination that can lead to corrosion. With a 1/8" stem diameter, this tool is highly versatile and compatible with a wide range of equipment, including CNC machining centers, milling machines, drill presses, and handheld corded or cordless drills.

Operating at a maximum speed of 2000 RPM, the Weiler 21082 provides efficient material removal for tasks such as removing burrs, rust, scale, and chips from internal diameters. Its compact 3/8" diameter and 1" brush length allow it to navigate tight spaces effectively, making it an essential tool for facility maintenance and precision parts finishing. Whether used in automated production lines or for manual touch-up work, this power tube brush delivers the reliability and quality expected from Weiler abrasive solutions.
