Tin Coated
Tin-coated drill bits are high-speed steel (HSS) drill bits that feature a thin layer of titanium nitride (TiN) coating, which enhances their durability and performance while giving them a distinctive gold appearance. This coating increases hardness and wear resistance, allowing the bits to maintain sharpness over time and withstand higher temperatures, reducing the risk of overheating during drilling. The smooth surface of the tin coating also decreases friction, enabling faster drilling speeds and cleaner holes. The heavy duty cosntruction makes it ideal for hard metals and other difficult to drill materials. Although they may have a higher initial cost, their extended lifespan and performance often result in cost savings over time, making them valuable for efficient and effective drilling tasks.
