20130272807 | CUTTING TOOL FOR MACHINING A WORKPIECE - A cutting tool for machining a workpiece. The cutting tool comprises a holder and at least two cutting inserts which are separated from each other by a spacer element. The cutting tool may be used to produce two or more bevels (and/or joints and/or grooves) at precisely defined spacings in only one operation. Through the use of spacer elements of different lengths, it is possible to produce bevels at different spacings. The spacer element preferably has an interface which comprises only radial contact surfaces, which run parallel to a longitudinal axis of the spacer element, and a substantially flat axial contact surface, which runs transverse to the longitudinal axis. The length of the spacer element can therefore be shortened on the rear side of the spacer element without destroying said interface. | 10-17-2013 |
