Carbide 3 Flute End Mill Aluminum Long Lifespan With High Helix Angles

Product Description:

Polishing And Passivation Process

Unique polishing passivation process effectively minimizes the coefficient of friction, particularly beneficial for materials like aluminum with gold, copper alloy, tempered plastic, and other non-metallic substances.

Sharp Edge Design

The sharp blade design decreases cutting resistance, leading to a significant reduction in burrs and vibration marks. It also features an enhanced chip evacuation function due to a deep groove design.

High Performance Aluminum Cutter

By undergoing fine grinding, the issue of chip sticking is effectively addressed. This results in the ability to meet higher standards in appearance quality and enhance 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.
