Cutter Aluminium Alloy
The EG30A series of high-precision corner-grooving end mills are professionally designed for non-ferrous metal cutting, renowned for their high performance and versatility. Featuring a 3-flute, 30° helix angle design, combined with a high-toughness carbide substrate and a multi-colored DLC coating, they offer low cutting resistance, excellent chip removal efficiency, and anti-sticking properties. This series of aluminum end mills not only boasts excellent wear resistance, but advanced grinding and manufacturing processes ensure cutting stability, providing 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 EG30A 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.
Achieves smoother cutting entry, reduces tool impact, and is especially suitable for machining thin-walled parts and easily deformable workpieces. Surface finish can reach below Ra0.4μm.
Surface hardness HV2800, low coefficient of friction as low as 0.2, effectively inhibits built-up edge formation, and has excellent anti-sticking performance, making it particularly 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, and suitable for high-speed cutting of easily sticking materials 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.
