The Brush will break off if:
○ machined beyond the maximum rotational speed
○ used with a pneumatic tool
○ rotated outside the cylinder (outside workpiece)
○ the distance from the hole entrance to the target is 20 mm or less
The clamp length must be 30mm or more when attaching this tool on the machine,
and make sure it is affixed rigidly.
In the following cases when used under the initial processing conditions, the Brush may break off,
○ Off-center cross hole, angled cross hole and long hole
○ The cross-hole diameter larger than φ12
When using this product on a cross-hole diameter larger than φ12, please contact us.
