18mm 4-Flute nACo Solid Carbide Square End Millfor HRC65 Hardened Steel
nACo (nano-AlCrN composite) coating represents the highest-performance tier in the square end mill range. With a coating hardness exceeding 3,800 HV and an oxidation temperature of 1,100°C, nACo enables dry cutting in hardened steel up to HRC65 — direct competition with CBN tooling at a fraction of the cost. 4-flute geometry with tight tolerance on corner radius (< 0.01mm) delivers consistent surface quality in die and mould hardened cavities, hardened shaft features, and precision gear blanks. Requires rigid fixturing and maximum 0.005mm spindle runout.

Where This Tool Excels
18mm nACo 4F — Recommended Applications
- ▸Heavy mould base and plate machining
- ▸Large structural steel profiling
- ▸Pressure vessel and flange features
- ▸Mining and energy equipment components
Machining Tip: At ø18mm, chip load per tooth should be verified against machine spindle power (minimum 15 kW recommended in HRC65 steel). Use high-feed circular interpolation entry (helical ramp) to avoid plunging at full width.
Coating Performance
nACo — Why It Works
- ▸Coating hardness > 3,800 HV — harder than TiN or TiAlN
- ▸Oxidation resistance to 1,100°C — enables dry cutting in hardened steel
- ▸Direct competitor to CBN at lower tooling cost
- ▸Ideal for die/mould cavities and hardened shaft features
