6mm 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.

R3mm TiSiN 4F — 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: R3mm 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.

Scallop Height vs Step-Over — R3mm

Residual scallop height (cusps) between adjacent tool paths, calculated for R3mm ball nose:

Step-OverStep-Over mmScallop Height (µm)Typical Ra (µm)
2% D10.120.60.12
5% D10.303.80.75
8% D10.489.61.92
10% D10.6015.03.01
15% D10.9033.96.79
20% D11.2060.612.12

h = R − √(R² − (ae/2)²). Actual Ra depends on feed rate, chip load, and material.

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
