MDA solid carbide drills for non-ferrous metals

Optimizing Surfaces with DLC Coating

The Diamond-Like Carbon (DLC) coating on MDA drills plays a critical role in addressing surface-related issues during material processing. This specialized coating provides several key benefits:

- Prevention of Material Adhesion: The DLC coating reliably prevents material from sticking to the tool surface. This results in an improved surface finish on the machined workpiece.

Properties of the DLC Coating
- Extremely Hard Surface: High hardness ensures durability and resistance to wear.
- Microhardness: Up to 2,200 HV (Vickers Hardness) provides exceptional resistance to indentation and scratching.
- Increased Wear Resistance: Extends the life of the tool, reducing the need for frequent replacements.
- Very Smooth Surface: Reduces friction and minimizes heat generation during machining.
- Minimized Coefficient of Friction: Ranges from 0.08 to 0.1, further reducing friction and improving cutting performance.

Benefits for Surface Quality
- High-Quality Surface Finish: Achieves a superior surface quality on the machined workpiece.
- Reduction of Built-Up Edge (BUE) and Material Welding: Prevents the formation of BUE and reduces the likelihood of material welding to the cutting edge.
- Improved Dimensional Accuracy: Enhances the precision and accuracy of the machined parts.

Additional Benefits
- Corrosion Protection: Shields the tool from corrosion, extending its lifespan.
- High Chemical Resistance: Protects against degradation from chemical exposure.
- Cosmetic Enhancement: Provides an aesthetically pleasing finish.

The DLC coating on MDA drills, therefore, offers an effective solution for common surface issues in material processing by creating a hard, smooth, and low-friction surface. This prevents material adhesion and significantly improves the surface quality of the finished product.
