12mm 4-Flute R1mm 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.

R1mm Corner Geometry
General-purpose fillet milling — strongest corner geometry for heavy passes
- ▸Maximum radial support on cutting edge during heavy DOC passes
- ▸Ideal for semi-finish passes before a smaller-radius finishing pass
- ▸Produces clean R1mm fillets in one pass — no secondary operation
- ▸Recommended for die cast tooling, injection mould cores, and structural pockets
ø12mm Applications
12mm TiSiN — Where This Tool Fits
- ▸Large mould and die shoulder milling
- ▸Structural bracket and frame pocketing
- ▸Transmission case features
- ▸Wind turbine blade mould profiling
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
