18mm 2-Flute TiSiN Solid Carbide Ball Nose End Millfor HRC55 3D Contouring & Mould Work
TiSiN-coated 2-flute ball nose end mills deliver superior chip clearance during 3D contouring and cavity machining in steel and stainless steel up to HRC55. With fewer flutes, cutting forces remain low during ramping, helical entry, and Z-level finishing passes — ideal for deep mould cavities and complex aerospace profiles. TiSiN hardness > 3,500 HV resists abrasion and oxidation at elevated cutting temperatures.

3D Finishing Reference
Scallop Height vs Step-Over — R9mm
Residual scallop height (cusps) between adjacent tool paths, calculated for R9mm ball nose:
| Step-Over | Step-Over mm | Scallop Height (µm) | Typical Ra (µm) |
|---|---|---|---|
| 2% D1 | 0.36 | 1.8 | ≈ 0.36 |
| 5% D1 | 0.90 | 11.3 | ≈ 2.25 |
| 8% D1 | 1.44 | 28.8 | ≈ 5.77 |
| 10% D1 | 1.80 | 45.1 | ≈ 9.02 |
| 15% D1 | 2.70 | 101.8 | ≈ 20.37 |
| 20% D1 | 3.60 | 181.8 | ≈ 36.37 |
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
- ▸2-flute: maximum chip clearance for deep cavity ramp entry
