Cutter Aluminium Alloy
The EAL350C 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, 55° helix angle design with an uncoated, high-gloss cutting edge, they combine high rigidity, low cutting resistance, and excellent anti-sticking performance. They are ideal for machining thin-walled aluminum alloy parts, precision contours, and grooves, 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 EAL350C a beast in aluminum machining, ideal for high-speed, high-gloss machining of aluminum alloys, copper alloys, and other non-ferrous metals.

Design details engineered for accuracy, tool life and process stability.
Achieves ultra-smooth progressive cutting, significantly reducing cutting resistance and vibration, with a surface finish below Ra0.2μm, approaching a mirror-like effect.
The tool surface is mirror-polished, with a friction coefficient as low as 0.25, effectively suppressing built-up edge formation, especially suitable for high-gloss machining of aluminum alloys.
The cutting edge undergoes ultra-precision grinding, balancing sharpness and chip resistance, avoiding coating residue affecting surface finish.
Optimized chip flute space, improving chip removal efficiency by 40%, preventing chip clogging, suitable for high-speed cutting of materials prone to tool sticking, such as aluminum alloys.
The cutting edge radius is controlled within 0.02mm, balancing sharpness and chip resistance, meeting the high-speed cutting requirements of non-ferrous metals.
The uncoated design avoids the risk of coating peeling and has excellent corrosion resistance, making it suitable for processing in humid environments.
