The Grit

Depending on the specific industrial application, different designations are used for the grain sizes. The table below shows an approximate comparison. This can serve as a guide for the selection of the appropriate grain size. Different materials lead to different results with the same grain size. BOTECH supports you in the selection of material and grain, with our experience from 20 years of brush technology.

Trimmed

All BOTECH disk brushes are trimmed to the exact same length (overall height) after manufacture. This guarantees that each tool has the same length (height) right from the start. Therefore, each brush is measured before packaging.
