AlTiN or TiAlN coating — does it matter?
| Coating | Runs best | Use for | Avoid in |
|---|---|---|---|
| TiN (gold) | Wet, moderate speed | General steel, taps | Aluminium, cast iron |
| TiCN | Wet or dry, harder | Stainless, harder steels | Deep pockets in aluminium |
| AlTiN / TiAlN | Hot and dry | Hardened steel, high speed milling | Aluminium — the aluminium sticks |
| DLC | Dry | Aluminium, composites, plastics | Steel |
Why people get confused: the two spellings describe the same aluminium-titanium-nitride layer; some tool listings put the aluminium first. Both need heat to form their oxide layer, so running them slow and wet wastes the coating.
Rule: aluminium and composites get DLC or uncoated polished. Hardened steel gets AlTiN, run hard. Everything else, cobalt HSS is enough.
