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/CR SOMT/CR LNHT insert holders on the
same plane with the two cutting edges set at an 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).
