10mm 4-Flute TiSiN Solid Carbide Ball Nose End Millfor HRC55 3D Contouring & Mould Work
The 4-flute TiSiN ball nose end mill is engineered for finishing passes and semi-finish Z-level contouring in steel and stainless steel up to HRC55. More cutting edges reduce per-tooth chip load, enabling higher feed rates while maintaining lower surface scallop height (Ra). TiSiN coating withstands the elevated temperatures of continuous 3D contouring on hardened mould surfaces without edge chipping.

3D Finishing Reference
Scallop Height vs Step-Over — R5mm
Residual scallop height (cusps) between adjacent tool paths, calculated for R5mm ball nose:
| Step-Over | Step-Over mm | Scallop Height (µm) | Typical Ra (µm) |
|---|---|---|---|
| 2% D1 | 0.20 | 1.0 | ≈ 0.20 |
| 5% D1 | 0.50 | 6.3 | ≈ 1.25 |
| 8% D1 | 0.80 | 16.0 | ≈ 3.21 |
| 10% D1 | 1.00 | 25.1 | ≈ 5.01 |
| 15% D1 | 1.50 | 56.6 | ≈ 11.31 |
| 20% D1 | 2.00 | 101.0 | ≈ 20.20 |
h = R − √(R² − (ae/2)²). Actual Ra depends on feed rate, chip load, and material.
Coating Performance
TiSiN — Why It Works for Ball-End Machining
- ▸TiSiN hardness > 3,500 HV — superior to TiAlN on ball-end profiles
- ▸Low friction reduces heat at ball-tip during 3D contouring
- ▸Suitable for dry, MQL, or flood coolant environments
- ▸4-flute: lower scallop height per pass for finishing operations
