Uncoated Carbide End Mill For Aluminum High Durability 3 Flute Aluminum End Mill

Product Description:

Polishing And Passivation Process

Unique polishing passivation process, greatly reducing the coefficient of friction. Especially suitable for aluminum with gold, copper alloy, tempered plastic and other non-metallic materials;

Sharp Edge Design

The sharp blade design reduces cutting resistance and greatly reduces the generation of burrs and vibration marks. Optimized chip evacuation function through deep groove design;

High Performance Aluminum Cutter

Through fine grinding, the problem of chip sticking is perfectly solved. Can achieve higher requirements on appearance effects and higher metal removal efficiency;

Key Features of Aluminum End Mills:

Material:
Typically made from carbide (solid carbide or carbide-tipped) for rigidity and heat resistance.

Flute Count:
Usually 2 or 3 flutes. Fewer flutes prevent chip clogging and improve chip evacuation (important for soft materials like aluminum).

Helix Angle:
High helix angles (typically 35°–45°) enhance chip removal and reduce heat buildup.

Surface Coating (or uncoated):
Often uncoated or coated with ZrN, TiB2, or DLC for better lubricity and reduced aluminum adhesion (galling). TiN is less common due to aluminum’s tendency to stick to it.

Geometry:
Polished flutes and sharp cutting edges help reduce built-up edge (BUE) and increase tool life. Corner radius or ball nose may be used for specific applications.
