CNC drilling produces clean, accurate holes in metal, plastic, and composite parts. While drilled surfaces are generally functional, applying post-drilling finishes can improve part longevity, surface integrity, and appearance, especially for components exposed to wear, moisture, or public view.
The default finish with visible tool marks and potential minor burrs at entry or exit points. Ideal for internal features or when aesthetics are not a concern
Type II: Enhances corrosion resistance and provides aesthetic color options. Common for aluminum parts.
Type III (Hard Anodizing): Offers a thicker, more durable finish with superior wear resistance.
A mechanical or manual process that removes sharp edges or residual material left around drilled holes.
Applies a thin zinc coating to drilled metal parts for excellent corrosion protection. Common in hardware, automotive, and industrial applications where moisture resistance is critical.
A chemical treatment for stainless steel parts that removes contaminants and enhances corrosion resistance, making it ideal for drilled components used in harsh environments.
Ideal for stainless steel parts. This electrochemical process smooths drilled surfaces, removes burrs, and enhances corrosion resistance while achieving a bright, clean finish.
Provides a uniform, durable outer layer that protects against corrosion and wear. Available in a wide variety of colors. Best for metal parts with exposed surfaces.

| Features | Recommended Size |
|---|---|
| Radii | Internal corners should have a minimum radius of 0.5 mm to avoid tool wear and ensure efficient chip removal during drilling. Larger radii (up to 2 mm) improve drill bit access and part longevity. |
| Threads and Tapped Holes | For standard drilled holes, ensure a diameter-to-depth ratio of 1:3 for best results. For tapping, the hole diameter should be 0.8x the nominal thread diameter for optimal threading. |
| Minimum Wall Thickness | For drilling, ensure a minimum wall thickness of 2 mm for metals and 3 mm for plastics to avoid material deformation and ensure stability during the process. |
| Text | For drilled text or markings, the minimum character height should be 2 mm, and the depth should be at least 0.5 mm to maintain visibility and durability. |
| Holes | Minimum hole diameter should be 2 mm for most materials. Larger diameters or deeper holes may require slower feed rates and specific tool selection to avoid tool wear. |
