Brush must be inserted from a main bore.
Burrs cannot be removed in case the brush is inserted from a secondary hole.
■ Processing beyond the maximum rotational speed may cause brush damage.
■ Process outside the cylinder (outside workpiece) may cause brush damage.
■ This tool is not suitable for off-center hole or angled cross hole.
■ In the following cases, brush damage may occur.
Select the brush color based on the workpiece material and burr root thickness.
Select Brush size based on main hole diameter (brush insertion hole).
Each Brush has 2 different length (M and L) except for φ1.5 brush diameter.
For a bore depth over 140mm, Extra-Long type is available as a customized item.
1. Insert the brush while not in motion.
*If you rotate the brush outside the cylinder, the bristles may be damaged or scattered and may cause injury to the operator.
2. Rotate the tool past the cross-hole
*Consistent edge quality can be obtained by rotating the tool in both CW and CCW direction.
3. Process while pulling the brush back.
*Pulling the brush back past the cross holes prevents burrs from being laid flat against the interior surface of the cylinder.
4. Process while pushing the brush forward.
*Pushing the brush forward ensures that burrs remaining upward are removed.
5. Stop the brush rotation.
6. Remove the brush while it is at rest.

Feed rate: 300mm/min.
Rotational direction: A uniform deburring and edge quality can be achieved by rotating the tool in both clockwise and counter-clockwise directions.
Recommended rotational speed is different depending on brush diameter.
See the recommended rotational speed and the target hole diameter shown below.
The continuous line (-) represents the recommended rotational speed.
The dotted line (- – -) represents the rotational speed when the brush is worn down 10mm.
You can continue to use the tool by adjusting (i.e. increasing) the rotational speed according to the wear amount.
