7mm 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.

Where This Tool Excels

7mm TiSiN 4F — Recommended Applications

  • ▸Automotive component profiling and slotting
  • ▸General CNC machining centre operations
  • ▸Pump and valve body pocket features
  • ▸Jig and fixture plate machining
Machining Tip: At ø7mm, the tool-to-work stiffness ratio is well-balanced. In HRC55 steel, aggressive parameters are achievable: axial depth up to 1×D, radial engagement 30–50% for profiling. Use climb milling for best surface finish.

Coating Performance

TiSiN — Why It Works

  • ▸TiSiN hardness > 3,500 HV — superior to TiAlN
  • ▸Excellent thermal stability in steel and stainless
  • ▸Low friction coefficient reduces cutting temperature
  • ▸Suitable for dry, MQL, or flood coolant environments
