Steel Tube Brush 3/8 in
Weiler 21282 is a round tube brush with steel wire and a single stem. It fits a 3/8 inch diameter and has an overall length of 3 1/2 inches. The brush length is 1 inch and the stem diameter is 1/8 inch. It is designed for use with a drill.
Mechanics cleaning small internal diameters
This brush suits technicians deburring or cleaning the inside of 3/8 inch tubes and cylinders. The steel wire handles light rust and carbon deposits. It is not for buyers who need larger bore sizes or aggressive material removal on heavy scale. The single spiral construction limits coverage on wider surfaces.
Maximum operating speed 2,000 RPM
The brush is rated for a maximum speed of 2,000 RPM when chucked into a compatible drill. Exceeding this limit risks wire fatigue and potential breakage during operation. Always match the tool speed to this rating for safe use. The 0.006 inch wire diameter supports flexibility at this velocity.

Questions about this item
How much heat does the steel wire generate when the brush runs at 2,000 RPM all day?
The 0.006 in wire diameter and 1 in brush length limit friction surface, so heat stays low during continuous drilling at the rated speed.
What drill chuck size is needed for the 1/8 in stem on this 21282 model?
Any drill with a 1/8 in or larger chuck will hold the stem securely for the rated 2,000 RPM operation.
Will the 3/8 in brush diameter fit inside the same tubes I clean with my older 1/4 in brushes?
No, the 3/8 in diameter requires a larger tube bore; it will not enter tubes sized for 1/4 in brushes.
