Design details engineered for accuracy, tool life and process stability.
Enables progressive cutting, reduces tool impact, and optimizes chip flute space, improving chip removal efficiency by 35%, suitable for high feed and large allowance cutting.
Surface hardness HV2800, low coefficient of friction as low as 0.3, effectively suppresses built-up edge formation, extending tool life by 2-2.5 times compared to uncoated tools.
Substrate hardness up to HRC64, combining high hardness and toughness, with twice the chipping resistance of ordinary end mills.
Core diameter is 12% larger than ordinary end mills, improving tool rigidity and maintaining machining stability even at high feed rates.
Four-Flute End Mills are suitable for various difficult-to-machine alloys, including SUS, chromium-nickel-iron alloys, and titanium alloys, and different tool materials can be selected according to the material.
Suitable for roughing and finishing, improving production efficiency while reducing tool change frequency.
The unique smooth, rounded corner shape helps to reduce cutting impact and improve chip resistance.
