4-side tungsten steel milling cutter, U-shaped groove titanium alloy special dynamic end mill

This 75° 4-flute U-groove dynamic end mill is a high-performance tool tailored for titanium alloy machining. Titanium alloy features low thermal conductivity, high hardness and strong viscosity, easily causing tool heating, adhesion and wear. This cutter adopts targeted structural and material optimization to adapt to high-load dynamic milling conditions.

It adopts ultra-fine grain tungsten carbide substrate with high hardness and toughness, preventing chipping and breaking during high-speed cutting. Equipped with premium AlTiCrN composite coating, it owns 1200℃ high-temperature resistance and low friction, effectively reducing tool adhesion and heat accumulation in titanium alloy processing.

The optimized large U-type chip groove ensures smooth chip removal, avoids clogging and secondary cutting, and improves machining efficiency and surface finish. The 75° cutting angle reduces cutting resistance and vibration, supporting high-feed & deep-cut dynamic milling. Unequal helix and unequal division design suppresses cutting resonance, ensuring long-term stable and high-precision machining.

This tool supports full-process machining of titanium alloy roughing, semi-finishing and finishing. It delivers higher efficiency and longer service life than ordinary end mills, reducing tool replacement frequency and production costs. It is also compatible with superalloy, stainless steel and other hard-to-cut materials, meeting high-standard precision manufacturing requirements.
