4mm 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

R2mm TiSiN 2F — Recommended Applications

  • ▸Mould cavity 3D finishing and detail contouring
  • ▸Aerospace turbine blade fillet machining
  • ▸Die casting insert surface finishing
  • ▸Medical device complex surface profiling
Machining Tip: R2mm is the most popular size for die and mould work. In HRC55 hardened steel, use 5–10% D1 step-over for semi-finishing, 2–5% for finishing. Feed rate 0.02–0.06 mm/tooth; adjust to keep scallop height ≤ 0.005mm for polishing-free finish.

3D Finishing Reference

Scallop Height vs Step-Over — R2mm

Residual scallop height (cusps) between adjacent tool paths, calculated for R2mm ball nose:

Step-OverStep-Over mmScallop Height (µm)Typical Ra (µm)
2% D10.080.4≈ 0.08
5% D10.202.5≈ 0.50
8% D10.326.4≈ 1.28
10% D10.4010.0≈ 2.01
15% D10.6022.6≈ 4.53
20% D10.8040.4≈ 8.08

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
