answer

When using the ADFLS-2D, it is necessary to center the diameter to be larger than the drill diameter to prevent the tool from running wild during chamfer due to a long overhang.
If the drill diameter is φ3 or less, it is about +0.5 mm.
If the drill diameter exceeds φ3, it is about +1 mm.
Note that point angle can be 90° or 120°.
