8mm 2-Flute TiSiN Solid Carbide Square End Millfor HRC55 Steel & Stainless

The 2-flute TiSiN variant offers maximum chip clearance for full-slot milling and deep pocketing in steel and stainless steel up to HRC55. Fewer flutes mean lower cutting forces and reduced heat accumulation in the cut, extending tool life in interrupted cuts, thin-wall features, and gang drilling operations. TiSiN coating prevents micro-chipping at high chip loads.

Where This Tool Excels

8mm TiSiN 2F — 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
