4mm 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
4mm nACo 4F — Recommended Applications
- ▸Die and mould fine detail features
- ▸Aerospace precision component profiling
- ▸Small hydraulic manifold pocketing
- ▸Electronic enclosure and heat-sink machining
Machining Tip: ø4mm is the most common size for precision detail work. In HRC65 steel, use 3–5× diameter axial depth with 30–50% radial engagement. TIR < 0.005mm at the tool tip is critical for consistent tool life.
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
