R Angle End Mills
The TC740 series is a professional-grade end mill designed for high-feed, high-efficiency metal cutting. It features a 4-flute, 40° helix angle design with a TiN gold coating and a high-toughness carbide substrate, offering high rigidity, low cutting resistance, and excellent wear resistance. It is widely used in aerospace, automotive, and mold manufacturing industries. In practical operation, selecting the appropriate tool type and parameters based on specific machining requirements is crucial to ensuring machining quality. The tool maintains stability under high speeds and high loads, avoiding vibration and chipping, ensuring consistent and reliable machining, making it an excellent choice for various applications.

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.
