60 Degree Engraving Endmill 2 Flutes CNC End Mill Customized With DLC Coating

60 Degree Engraving Endmill 2 Flutes CNC Tool With DLC Coating For Aluminiun And Brass

Introduction:

A 60-degree engraving endmill with 2 flutes and DLC coating is an excellent choice for precision engraving, chamfering, and detail work in aluminum and brass. 

Features:

60° Tapered Tip Design:

• • Perfect for V-shaped engraving, lettering, deburring, and chamfering.

  • Creates sharp, clean lines with precise angles.

2-Flute Design:

• • Optimized for non-ferrous metals (Aluminum & Brass) to prevent chip clogging.

  • Provides efficient chip evacuation and smooth cutting.

DLC Coating (Diamond-Like Carbon):

• • Ultra-low friction, reducing built-up edge (BUE) in sticky materials like aluminum.

  • High wear resistance, extending tool life in abrasive brass alloys.

  • Chemical inertness prevents material adhesion.

Solid Carbide Construction:

• • Ensures rigidity and precision in high-speed engraving applications.

Recommended Applications:

✔ Engraving serial numbers, logos, or fine details

✔ Chamfering edges (45°–60° angles)

✔ 3D contouring in jewelry making & precision molds

✔ PCB milling (if fine-tipped)

Why DLC Coating for Aluminum/Brass?

DLC (Diamond-Like Carbon) coating is one of the best choices for machining aluminum, brass, and other non-ferrous metals due to its unique properties:

1. Prevents Built-Up Edge (BUE) & Material Adhesion

• Aluminum and brass are "sticky" metals that tend to weld onto cutting tools, causing:

  • Poor surface finish

  • Increased friction & heat

  • Premature tool failure

• DLC’s ultra-smooth, low-friction surface prevents material from sticking, keeping the tool clean and cutting efficiently.

2. Reduces Friction & Heat Generation

• DLC has a coefficient of friction close to Teflon, minimizing heat buildup.

• Critical for high-speed machining of aluminum, where excessive heat can soften the workpiece.

3. Chemical Inertness (Non-Reactive with Aluminum/Brass)

• Unlike TiN or AlTiN (which contain titanium), DLC does not chemically react with aluminum, preventing diffusion wear.

• This makes it far better than standard coatings for long-duration cutting in non-ferrous metals.

4. Exceptional Wear Resistance (Even Without High Hardness)

• While not as hard as AlTiN or diamond coatings, DLC’s self-lubricating properties reduce abrasive wear in:

  • Silicon-rich aluminum (e.g., 6061, 7075)

  • Abrasive brass alloys (e.g., free-machining brass with lead)

5. Mirror-Like Surface Finish

• The smooth cutting action of DLC-coated tools produces near-polished finishes in brass and aluminum, reducing the need for secondary polishing.
