10mm 4-Flute R0.2mm 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.

R0.2mm Corner Geometry

Micro edge protection — minimal corner rounding for near-sharp corner features

  • ▸Virtually sharp corner appearance while eliminating micro-chipping
  • ▸Ideal where fillet radius tolerance is ± 0.05mm
  • ▸Extends tool life vs true sharp-corner tools by 30–50%
  • ▸Suitable for precision mould parting surfaces and embossed lettering
Radius Selection Tip: R0.2mm is the tightest corner radius standard. In HRC55 steel, the R0.2mm arc is small enough to appear visually sharp but prevents the notching failure that destroys zero-radius tools. Use identical step-over and depth parameters as you would for a square end mill.

ø10mm Applications

10mm TiSiN — Where This Tool Fits

  • ▸Automotive component shoulder milling
  • ▸Pump body and valve pocket features
  • ▸Gearbox cover profiling
  • ▸Large mould runner channel machining
Machining Tip: ø10mm is the production sweet spot for corner radius end mills. In HRC55 steel, radial engagement can be 30–50% of D for profiling, with DOC up to 1×D for semi-finish passes. The corner radius reduces chatter significantly at this diameter.

Coating Performance

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
