Cutter Aluminium Alloy
The EG40C series high-precision fillet groove end mills are short-flute professional-grade end mills specifically designed for high-speed, high-precision machining of aluminum alloys. Featuring a 3-flute, 40° helix angle design with a short cutting edge, combined with a high-toughness carbide substrate and a multi-colored DLC coating, they offer high rigidity, low cutting resistance, and excellent anti-sticking performance, making them ideal for machining thin-walled aluminum alloy parts, precision contours, and grooves. They provide users with efficient and reliable machining solutions. Primarily developed for the aerospace market, they are also suitable for general engineering industries. This combination of accelerated machining and the ability to handle advanced ramp angles makes the EG40C a beast in aluminum machining, ideal for high-speed, high-finish machining of aluminum alloys, copper alloys, and other non-ferrous metals.

Design details engineered for accuracy, tool life and process stability.
Enables smoother cutting entry, reduces tool impact, and increases chip flute space, improving chip removal efficiency by 35%, suitable for high-speed cutting of aluminum alloys.
Surface hardness HV2800, low coefficient of friction as low as 0.2, effectively inhibits built-up edge formation, and has excellent anti-sticking performance, especially suitable for aluminum alloy machining.
The coating can withstand temperatures up to 800°C and maintains excellent wear resistance even under high-speed dry cutting, extending tool life by 2-2.5 times compared to uncoated tools.
Optimizes chip flute space, improving chip removal efficiency by 30%, avoiding chip clogging, suitable for high-speed cutting of materials prone to tool sticking such as aluminum alloys.
The edge radius is controlled within 0.02mm, balancing edge sharpness and anti-chipping ability, meeting the high-speed cutting requirements of non-ferrous metals.
Double rake grooves improve ramp/entry capability and reduce spindle load, and can be widely used in roughing, semi-finishing and finishing.
