DLC Carbide Ball Nose End Mill Overview

This DLC-coated 2-flute solid carbide ball nose end mill is designed for 3D contouring, profiling and finishing in aluminum and selected non-ferrous materials. Full-radius geometry, wide chip space and a low-friction DLC surface support stable machining, while standard and custom sizes are available for repeat supply and OEM programs.

Technical Design Features

Sharp Cutting Edge & Reinforced Core

Negative-rake cutting-edge geometry combines cutting sharpness with improved edge strength for stable aluminum machining.

A large-core design increases tool rigidity, supports stable cutting and chip evacuation, and helps reduce the risk of edge chipping.

35 degree helix geometry and wide flute space for aluminum machining

35° Helix & Precision-Ground Flutes

The 35° helix angle and precision-ground spiral flute geometry provide enlarged chip space for aluminum machining.

Smooth chip evacuation helps reduce chip adhesion and recutting while supporting higher-efficiency 3D contouring, profiling and finishing.

Multi-Layer DLC Coating Structure

A 5-layer coating structure improves surface hardness, wear resistance and thermal performance during continuous machining.

The low-friction DLC surface helps reduce aluminum adhesion, built-up edge and tool wear, supporting stable high-efficiency non-ferrous machining.

Precision-ground solid carbide shank for aluminum end mill

Precision-Ground Shank

The precision-ground straight shank is controlled to a 0 / -0.005 mm diameter tolerance for stable clamping and repeatable tool positioning.

Tight shank control helps reduce vibration and chatter, supporting stable cutting and consistent machining performance.
