Locating hole 1
Locating hole 2
Indexable cutting inserts for milling bevels
The cutting inserts for milling edges must be fas‐
tened to the mounting seat on the milling head by
means of the original locking screws (max. tighten‐
ing torque: 4.0–5.0 Nm).
As each insert has four cutting edges, it can each
be indexed a total of four times before requiring
replacement.

As the inserts are each approximately 11 mm long,
each insert can be indexed four times while fas‐
tened via the lower locating hole and a fur‐
ther four times while fastened via the middle lo‐
cating hole provided that the width of the
bevel being cut is less than or equal to 5.0 mm.
Therefore, if the width of the bevels being milled is
not greater than 5 mm, each insert can be used a
total of eight times before requiring replacement.
To facilitate the milling of tight contours and small
2
bores, a small guide bearing (DS) is also available
as an accessory to each milling head. When the DS
guide bearing is fitted, the cutting inserts can be
used a total of four times.

CAUTION!
It is extremely important to ensure
that the lower corner of the
cutting insert is always covered by
the guide bearing DL or DS.
