Chipping

UT tolerance (ø0.3mm): 0.004mm or less

Hole Qualities

A:Burr

Blunt cutting edge makes a burr.

B:Others

In the case of high frequency of chipping, there is a possibility to create an unevenness of hole quality, therefore this should be controlled.
However in our tests we found no serious effect on registration accuracy and roughness.

Countermeasure (Setting of drill point)

1.Pay attention to handling

Use putty to remove dust

2.Dress the primary wheel.

Use a suitable dressing stick to dress the primary grinding wheel.
