Precautions when installing notched inserts

1. Install notched inserts by matching the insert with the number of marks 2. When installing notched inserts in flute line, ensure that the number on
on the holder body. the insert is the same as the insert in first stage. Ref. to Fig.1, 2 and 3.

Insert Number and Holder Marks

Insert Size 11 Type 17 Type
Same Flute Line

Using the cutter with the inserts installed incorrectly will damage the holder.
