8mm 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
8mm 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 ø8mm, 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
