Professional tube brush for internal cleaning
The Weiler 21108 double spiral tube brush is built for machinists and maintenance technicians who need reliable internal surface preparation. Its steel wire construction and double spiral design deliver consistent cleaning action inside tubes and bores. The 1/4 inch stem fits standard drill chucks, drill presses, and CNC machines for versatile workshop use. Supplied in a pack of 10 for production environments.
Ideal for deburring and finishing metal interiors
This brush suits operators removing rust, scale, or light burrs from ferrous metal tubing where a 3/4 inch diameter matches the bore. The 0.006 inch wire provides fine surface finishing without aggressive material removal. It is not suited for non-ferrous metals where steel wire may cause contamination or for large-diameter pipes exceeding the brush size. Users requiring softer bristle materials or larger diameters should consider alternative brush types.
Maximum 2000 RPM operating speed limits machine
The 2000 RPM maximum speed rating is the critical specification determining tool compatibility. Exceeding this limit risks wire breakage and unsafe operation on high-speed routers or grinders. The 5 1/2 inch overall length and 2 1/2 inch brush length define reach inside the workpiece. Verify your equipment runs at or below this speed before installation.

Questions about this item
What comes in the package and do I need a separate tool holder?
The box contains ten double-spiral tube wire brushes, model 21108. Each brush has a 1/4 in stem that fits standard drill chucks, CNC machines or drill presses, so no extra holder is required.
How do I choose between the listed versions or capacities for this brush?
This item is sold as a single specification: 3/4 in brush diameter, 2 1/2 in brush length, .006 in wire diameter and 5 1/2 in overall length. There are no alternative versions or capacities to select.
What does the 2,000 RPM maximum speed mean when the brush is running in my drill?
It is the highest safe operating speed; running the brush faster than 2,000 RPM can cause wire breakage or unsafe vibration, so set your drill or CNC spindle at or below that limit.
