KYOCERA SGS Precision Tools Reveals Coolant-Through Expansion of Popular 7-Flute End Mill Line

February 9, 2024 9:09 am

KYOCERA SGS Precision Tools announces a large expansion of the popular H-Carb seven-flute high-efficiency end mill series with over 400 new coolant-through options.

Available in various lengths of cut, the new H-Carb Series 77 coolant-through end mills specialize in deep axial trochoidal and high-speed machining applications. The new coolant-through varieties offer better wear, surface finish, and chip evacuation when pocketing or slotting. The H-Carb’s specially designed core and flute design improve rigidity and chip flow while reducing deflection. The seven-flute design allows for superior finishes at higher speed and feed rates versus 5 and 6 flute tools.

The expanded H-Carb portfolio features specialized Ti-NAMITE®-A or Ti-NAMITE®-M coating technology for increased wear and abrasion resistance extending tool life dramatically to tackle a wide range of materials and applications. The Chip Breaker profile is standard option with a wide range of square end and corner radii options offered to meet a variety of machining specifications.
