4-side for stainless steel special hard alloy U-shaped groove high hardness and high-efficiency dynamic tungsten steel milling cutter

Our 75° 4-flute U-groove dynamic milling cutter is a high-precision industrial cutting tool customized for difficult-to-machine metals, especially stainless steel. Different from standard ordinary end mills, the upgraded 75° large front angle greatly reduces cutting resistance and inhibits workpiece work hardening during stainless steel machining. The widened and deepened U-shaped flute enables fast and smooth chip evacuation, effectively avoiding chip clogging, tool burning and workpiece scratches to ensure continuous and stable cutting.

The cutter body is made of imported ultra-fine grain solid carbide with high density and strong compression resistance, preventing blade chipping, deformation and abrasion under high-load cutting conditions. The 4-flute symmetrical balance structure ensures uniform cutting force distribution, suppresses vibration and tool runout, and upgrades workpiece dimensional accuracy and surface finish. Compatible with high-feed dynamic milling technology, it realizes one-step forming of roughing and finishing, avoiding repeated tool changes and secondary processing. All products are precisely ground by high-precision CNC equipment with strict tolerance control, stable batch consistency and long service life, suitable for long-term industrial mass production.
