Type–MFWN Square Face Milling Cutter

Kr=90°
Standard diameter: 50-250mm
More options for inserts
6 cutting edges achieve better machining economy.
Insert has wide-area applications which is suitable for machining cast iron, steel, stainless steel and difficult-to-machine materials.
Excellent matching of cutter body and insert is close to perfect 90 degree vertical.
A variety of machining areas is feasible including surface, step, groove and vertical milling.
The design of large front angle and dynamic slope provides low resistance and vibration during machining. The roughness of workpiece surface is also improved.

Testing Equipment: Tool Presetting and Measuring Machine from ZOLLER, Germany

Most of cutters in the market is difficult to avoid the angle deviation problem of Figure 2 and Figure 3 because it is necessary to take into account inserts from different brands;However DEREK cutter is based on the DEREK own inserts, which results in the installation and matching machining as shown in Figure 1. It can achieve a near-perfect 90°design.
