* The brush size is approximate as the tip expands by rotating.

Precautions for use

The Brush will break off if:
○ machined beyond the maximum rotational speed
○ used with a pneumatic tool
○ rotated outside the cylinder (outside workpiece)

In the following cases, the Brush may break off,
○ Off-center cross hole and angled cross hole
○ T-shaped hole: If the cross hole diameter is 100% of the main bore diameter or more.
○ Cross-shaped hole: If the cross hole diameter is 70% of the main bore diameter or more.
