CoroMill® 300 light-cutting face and profile milling cutters

Helical ramping of larger diameter holes with CoroMill® 300 is a very secure and productive method in this case. The cutting forces are much lower than for drilling operations, which are challenging when dealing with the interrupted exit into the bore.

For rough milling around a boss, use CoroMill® 300 with a roll-in program combined with round inserts to reduce notch wear and allow for high feed rates.

Grade S30T – designed for challenging super-alloy machining

Grade S30T is a PVD-coated carbide grade​ optimized for titanium milling, excellent for finishing to light roughing. This thin-coated grade enables very sharp cutting edges that resist fatigue and micro-chipping, allowing the cutting edges to be preserved for longer times in cut at higher cutting speeds.
