5-2. Using Cutter
CAUTION
●
Use One-Touch type cutters only.
●
For better workability and safety, do not use
worn or damaged cutters.
5-3. Combination of Cutter and Pilot Pin
CAUTION
●
Do not use any other combinations than those
shown in the compatibility table.
Use a Pilot Pin appropriate for the cutter. (Fig. 10)
A Pilot Pin to be used varies depending on the cutter
type, diameter, length (depth). A wrong combination
of cutter and Pilot Pin would not allow slug to be
ejected at the end of drilling and/or prevent Cutting
Oil from reaching the cutting point, resulting in
cutting tool damage.
