75 approach angle better for:
Shoulder clearance inside bores
Profiling & step boring
Compatible with CNMG12 inserts (strong, economical)
Designed for medium to heavy internal machining
High rigidity due to 40 mm thick bar
Suitable for steel, cast iron, alloy materials
Tools with K geometry typically have a 75 cutting edge angle, which changes cutting direction and chip flow compared to 95 holders .
