When producing high quality grooves there is often a need for chamfered corners. One way
to produce these is to use a standard width CoroCut GF insert and after the groove is made,
use the corners of the insert to chamfer, see illustration A.
A more productive way when machining large series is to order a Tailor Made insert with the
exact form of the groove, see illustration B. Often cutting time can be reduced by up to 50%
compared to the previous method. In this case shape option 16 is used.
