SPK® Precision Tools for Milling

90° Square Shoulder Milling with the MKS 90 Milling System

This square shoulder milling cutter from CeramTec’s MKS series with 90° setting angle and TNCN 16xx indexable inserts enables maximum cutting depths and shoulder heights for rough milling applications.

The great cutting depth and shoulder height reduces the number of cutting paths. Used in combination with SPK® cutting materials it is possible to achieve feed rates of up to 10 m/min when milling cast iron materials. Specially designed finishing geometries with six cutters per insert are available for finish milling applications to generate surface qualities in the Rz 3.0 μm range.
