Drill Bits Coating
| Coating | Photo | Specifications |
| Bright Drill Bits Coating (Polished Metal) | 
|
Bit polishing helps reduce friction. For woods, plastics, and aluminum. |
| Black Oxide (Black) | Oxide helps hold a thin film of lubricant better than a shiny finish, it helps reduce friction. For ferrous materials preferably. | |
| TiN – Titanium Nitride (Gold yellow) | 
|
Coating resists friction and improves the heat transfer, providing longer life in comparison with standard high-speed steel bits. |
| TiCN – Titanium Carbo-Nitride (Reddish yellow to violet) | 
|
It is harder and more durable than other coatings. Used for cast iron, stainless steel, and aluminum. |
| AlTiN – Titanium Aluminum Nitride
(Bluish-Violet-Black) |
|
Designed to increase the temperature resistance and hardness. The bits are heat resistant up to 800 degrees Celsius. Not used for aluminum. |
| ZrN – Zirconium Nitride (Brass colored)
|
|
Strengthens brittle drill bit types and decreases friction. Excellent for precision drilling. Has reduced the risk of accidental damage on brittle bit types. |
