4-Flute · TiSiN · HRC55 · Standard Reach
12mm 4-Flute TiSiN Solid Carbide Square End Millfor HRC55 Steel & Stainless
TiSiN (Titanium Silicon Nitride) coating provides excellent heat resistance and hardness up to 3,500 HV — ideal for dry or near-dry cutting in steel, stainless steel, and cast iron up to HRC55. The 4-flute geometry maximises radial contact and surface finish in profiling, shoulder milling, and finishing passes. Walter CNC 5-axis grinding ensures precise corner geometry and equal pitch between flutes.
