Titanium Nitride Coated Drill Bit - 5/16In - Hanson

The Hanson 63920 Titanium Nitride (TiN) Coated Drill Bit, 5/16-inch, is engineered for professional technicians and mechanics seeking superior durability and precision in their drilling applications. This jobber length drill bit features an advanced TiN coating that significantly extends its lifespan and enhances performance, making it an indispensable tool for demanding automotive and industrial tasks. Its specialized design ensures efficient and accurate hole creation across a variety of tough materials.

Key Features

• Extended Tool Life: The distinctive gold-colored titanium nitride coating provides exceptional wear resistance, allowing the drill bit to last up to six times longer than standard high-speed steel drill bits. This coating creates a thermal barrier, reducing friction and heat buildup during drilling, which helps the bit remain sharper for extended use.
• Superior Hardness: With a hardness rating of approximately 80 Rockwell C, the TiN coating is very hard, offering increased resistance to abrasion and ensuring consistent performance in challenging materials.
• Precision Drilling: A 135-degree split point design facilitates immediate drilling contact, minimizing bit "walk" or "skate" and enabling accurate hole placement without the need for a pilot hole. This self-centering feature reduces the feed pressure required for penetration and prevents work hardening of the material.
• Reduced Friction & Enhanced Chip Flow: The low-friction TiN coating improves chip evacuation, promoting cooler operation and extending the bit's effectiveness.
• Robust Construction: A heavy-duty web design provides extreme rigidity, enhancing stability and reducing bit flex, particularly when drilling in metal applications.

Applications

This professional-grade drill bit is ideal for repetitive drilling and production work in automotive repair, industrial maintenance, and fabrication settings. It excels in drilling through various materials including carbon steel, alloy steel, cast iron, and stainless steel, making it a reliable choice for mechanics and industrial technicians requiring consistent, high-performance results. Its design is particularly suited for hard metals and high tensile strength materials.
