Tool Geometry & Core Features

2-Flute Configuration: Provides large flute valleys for fast chip evacuation, which is critical when machining gummy materials like aluminum to avoid "chip welding".
Square/Flat Nose: Essential for producing crisp 90-degree corners, flat floors in pockets, and precise side-wall profiling.
Micrograin Tungsten Carbide Substrate: Delivers outstanding substrate hardness (often over 91-92 HRA or HRC 55-65), rigidity, and deflection resistance compared to high-speed steel (HSS).

Coating Guide for Aluminum Machining

While your list names several industrial coatings, choosing the right physical vapor deposition (PVD) finish drastically impacts tool life and performance when cutting non-ferrous metals:

Nano Blue (NaCo) Coating: Highly recommended. This ultra-fine micro-layer offers extreme surface hardness (HRC ≥ 65) and exceptional lubricity. It maintains razor-sharp cutting edges and repels thermal load into the discarded chips.
TiAlN (Titanium Aluminum Nitride) / AlTiN: These are industry-standard coatings designed for high heat resistance, forming a protective aluminum oxide layer at high temperatures. While effective for general purpose and steels, they contain aluminum, which can occasionally cause micro-welding when dry-cutting soft aluminum alloys.
CrAlN (Chromium Aluminum Nitride) & TiSiN (Titanium Silicon Nitride): Optimized for extreme environments. CrAlN provides great corrosion and wear resistance in high-feed setups, while TiSiN handles ultra-hard steels and difficult alloys up to HRC 60+.
