DLC-Coated Inch-Size Aluminum Square End Mill Overview
This inch-size DLC-coated solid carbide square end mill is designed for CNC machining of aluminum alloys and selected non-ferrous materials. Its 3-flute geometry, polished flutes and low-friction DLC coating help reduce aluminum adhesion, improve chip evacuation and support stable surface quality. Fractional inch sizes and custom supply are available.
Key Configuration
Imperial Inch Sizes
Fractional dimensions support imperial drawings, toolholders and replacement-tool applications.
3-Flute Aluminum Geometry
Balanced flute design provides chip space, rigidity and efficient cutting performance.
DLC Low-Friction Coating
DLC coating helps reduce aluminum adhesion and built-up edge during machining.
Key Design Features

Fully Ground Cutting Edge
Precision-ground edges support sharp cutting performance and consistent aluminum machining results.
High-Capacity Chip Removal
Optimized flute space improves chip evacuation for efficient high-speed milling.


Large Core Diameter Design
Reinforced core geometry improves tool rigidity and supports stable cutting conditions.
Universal Round Shank Design
Standard shank design provides reliable tool holding and convenient CNC setup.

DLC Coating for Aluminum Machining

The low-friction DLC coating helps reduce aluminum adhesion and built-up edge while supporting cleaner chip flow and improved surface finish. It is mainly designed for aluminum machining and selected non-ferrous applications.
Recommended Workpiece Materials

Designed primarily for aluminum machining, with selected applications in non-ferrous materials and plastics requiring clean cutting performance.
Suitable Milling Operations
The square-end geometry is suitable for common aluminum milling applications. Final cutting conditions should be adjusted according to tool diameter, engagement, workpiece grade and machine rigidity.
