Unique flute design and high performance geometries in one tool. Super low RA surface finish (18 RA to 22 RA) on critical cutting edge surfaces reduces friction and improves chip formation. The eccentric outside diameter relief helps reduce horizontal milling lines and keeps chatter and squall to a minimum. New design allows for higher feed per tooth rates for greater productivity. Full form ground flutes with true flute rake angle geometries make this tool cut freely with outstanding chip evacuation. Eccentric ground relief. Heavy duty tooth structure. Advanced chip evacuation ramp. CNC qualified.
