Rough face milling
Program a roll into cut in a clockwise motion (counter-clockwise will not solve the thick chip thickness problem). By rolling into cut, the chip thickness on exit is always zero, allowing for higher feed and longer tool life. A round insert cutter provides best productivity and tool life thanks to the lead angle and chip-thinning effect. CoroMill® 300 with S30T and S40T has through coolant and close pitch option, therefore optimized for titanium. Now available in insert sizes up to 20 mm (metric) or 1.0’’ (inch).
