* The brush size is approximate as the tip expands by rotating.
* CH-A12-3M/L, and CH-A12-7M/L are equipped with a protection tube.

Precautions for use

The Brush will break off when:
○ being machined beyond the maximum rotational speed
○ being used with a pneumatic tool
○ being 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 equal to or greater than the main bore diameter.
○ cross-shaped hole: if the cross hole diameter is more than 70% of the main bore diameter.
