13mm 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

13mm TiSiN 4F — Recommended Applications

  • ▸Large mould and die cavity machining
  • ▸Structural component pocketing
  • ▸Gearbox and transmission case features
  • ▸Wind turbine component contouring
Machining Tip: ø13mm produces significant cutting forces. Ensure workholding clamping force is adequate. In HRC55 steel, reduce axial DOC to 0.5×D for first passes to verify fixturing stability before committing to full depth.

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
