Insert Technology for Roughing and Finishing in One Step

The challenge which must be met by tools enabling roughing and finishing in a single process is to achieve the required roundness and concentricity, taking account of the high cutting performance and the associated forces. For this reason, such tools are normally fitted with guide pads; however, these can lead to problems during machining.
The newly developed roughing/finishing tools are based on an innovation in indexable insert technology, which makes it possible not only to bore, but to finish as well using economical, multi-bladed indexable inserts. Thanks to an innovative cutting head geometry with support land, previously commonplace guide rails are a thing of the past.
Due to the innovative fine adjustment of indexable inserts, it is possible to easily adjust every single indexable insert with μm accuracy.


The tools are specially manufactured for each application, with four to six cutting edges on a main body and for diameter ratios up to 5×D. With various cutting tool material/coating variants, they can also be ideally adapted to customer requirements for specific materials. For example, in GGG50 the new machine tools work to cutting depths from three to four millimetres (ap) whereby, bore tolerances to IT8 are possible.

Your PLUS:

  •  Two processes – roughing and finishing – in one
  •  Uses economical, multi-bladed indexable inserts
  •  Interchangeability of the cutting heads reduces tool costs
  •  Adjustable indexable inserts allow for μm-precise setup
  •  Maximum precision
