Fig. a Fig. b Fig. c

1. Radial setting of the cutting edges should be
carried out with tool presetting equipment.
2. Boring bars fitted with two insert pockets are for
roughing operations involving heavy chip removal.
The double-insert boring bars include:
- Two IHSR insert holders on the same plane with
the two cutting edges set at identical radial distance
for high feed rate roughing operations (Fig. a).
- An IHCR insert holder and an IHSR insert holder not on the
same plane with the two cutting edges set at different radial
distances for high-depth roughing operations (Fig. b).
3. Boring bars fitted with a single insert holder are for roughing
and finishing operations involving normal chip removal.
The serrated surface protection plate PLT
should always be used (Fig. c).
