6mm 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.

6mm TiSiN 2F — Recommended Applications

  • Die and mould fine detail features
  • Aerospace precision component profiling
  • Small hydraulic manifold pocketing
  • Electronic enclosure and heat-sink machining
Machining Tip: ø6mm is the most common size for precision detail work. In HRC55 steel, use 3–5× diameter axial depth with 30–50% radial engagement. TIR < 0.005mm at the tool tip is critical for consistent tool life.

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
