6mm 4-Flute R0.5mm TiSiN Solid Carbide Corner Radius End Millfor HRC55 Steel & Stainless

TiSiN-coated 4-flute corner radius end mills combine the rigidity of a square end mill with corner geometry that reduces stress concentration and micro-chipping on hardened surfaces up to HRC55. The corner radius distributes cutting load across a wider arc at entry, dramatically extending tool life versus sharp-corner tools in steel and stainless steel shoulder milling and semi-finish passes. TiSiN hardness > 3,500 HV resists abrasion at continuous contact conditions.

Industry standard fillet — most common CNC pocket and shoulder radius

  • Longest tool life in class for shoulder milling and pocketing
  • Matches ISO standard pocket corner specification R0.5mm
  • Reduces cutting forces by ~20% vs sharp corner in hardened steel
  • Available in full standard size range including long-reach variants
Radius Selection Tip: R0.5mm is the most universal specification. In HRC55 steel, it provides the best balance of fillet feature accuracy, tool life, and chatter resistance. Recommended for all new mould base and structural component programmes unless design specifically requires R < 0.5mm.

6mm TiSiN — Where This Tool Fits

  • Mould cavity pocket semi-finishing
  • Precision aerospace part profiling
  • Hydraulic manifold pocket corners
  • Small fixture and jig features
Machining Tip: ø6mm with corner radius provides the best size-to-stiffness ratio for die and mould work. In HRC55 steel, the corner radius allows 3–5×D axial depth without the micro-chipping that limits sharp-corner tools. Ideal for continuous shoulder milling passes.

TiSiN on Corner Radius Geometry

  • TiSiN hardness > 3,500 HV on curved corner arc geometry
  • Prevents micro-chipping at re-entry in interrupted shoulder milling
  • Low friction for reduced built-up edge in stainless steel shoulder cuts
  • Dry, MQL, or flood coolant — all environments supported
