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
