Boring bars
starting from 5 mm working diameter
… versatile
HOLLFELDER-GHRING CUTTING TOOLS
creates the basis for a versatile production on turning machines (lathes). This range of boring bars
starting from 5 mm will satisfy all your requirements.
The various product ranges are tted to each other in such a way as to offer a wide range of applications to
the user. Depending on the individual application you can choose among boring bars with steel- or carbide
shanks as well as among different insert geometries and approach angles. The boring bars with carbide
shank and internal coolant supply in particular enable the use of large L/D (length-diameter) relations.
The precisionground inserts offer the highest degree of precision and cutting performance independent of the
geometry of the boring bar. The positive chipbreaker geometries of the inserts are responsible for an advan-
tageous chip forming, reduced machining force on the insert, excellent chip ow and as a result a superior
process stability even under difcult machining conditions and at unstable workpieces.
