Excessive contact pressure does not improve the result, but increases the required drive power and reduces the working life of the brush.

Brush access to restricted places Twisted knot end cup brush opens due to centrifugal force. Deburring Round brushes with waved wire Rust removal, paint removal Cup brushes for use on surfaces. Cleaning, deburring, blending, linishing Abrasive bristles for very fine surface finishes. l nan.n circular brushes Multi-row - of steel wire / stainless steel wire Waved steel wire or stainless steel wire firmly crimped into the steel body. High density, high concentricity, and good wear resistance. Adaptable to various different mounting bores by use of interchangeable reducing rings (supplied). Size 250x30; 300x35 - Bore with double spline. Application: For roughening, cleaning, removing rust, and scale etc. Use on bench grinder or polishing machines, or on machines with flexible drive heads.
