3mm 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.

Where This Tool Excels
R1.5mm TiSiN 2F — Recommended Applications
- ▸Micro-mould texture and fine engraving
- ▸Medical implant surface contouring
- ▸Watch case and jewellery component 3D finishing
- ▸Electrode finishing for micro-EDM
Machining Tip: R1.5mm is a micro ball — spindle runout must be ≤ 0.002mm. Use ER collet with ≤ 3µm accuracy. In HRC55 hardened steel, step-over 3–5% of D1 for mirror finish. Scallop height at 5% step-over ≈ 0.0037mm.
3D Finishing Reference
Scallop Height vs Step-Over — R1.5mm
Residual scallop height (cusps) between adjacent tool paths, calculated for R1.5mm ball nose:
| Step-Over | Step-Over mm | Scallop Height (µm) | Typical Ra (µm) |
|---|---|---|---|
| 2% D1 | 0.06 | 0.3 | ≈ 0.06 |
| 5% D1 | 0.15 | 1.9 | ≈ 0.38 |
| 8% D1 | 0.24 | 4.8 | ≈ 0.96 |
| 10% D1 | 0.30 | 7.5 | ≈ 1.50 |
| 15% D1 | 0.45 | 17.0 | ≈ 3.39 |
| 20% D1 | 0.60 | 30.3 | ≈ 6.06 |
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
