These Cobalt Drills from Drill America offer exceptional performance when drilling through tough materials such as stainless steel, Inconel, and titanium. Manufactured to Aerospace Standard 907, they display high red hardness, enabling speeds up to 30% greater than conventional M2 high-speed steel drills. The Cobalt steel construction provides extended tool life compared to high-speed steel, while maintaining the drill bits' toughness and hardness even in high-temperature drilling conditions.

The unique design of these Cobalt Drill Bits includes a self-centering 135-degree split point, which allows them to penetrate hard materials without the need for a pilot hole. This feature also produces smaller chips, reducing the risk of clogging compared to the more common 118-degree point. Additionally, the gold oxide finish acts as a lubricant and provides excellent wear resistance, further enhancing the longevity of these drill bits.

The round shanks of the drill bits accommodate a wide variety of tool-holding systems, ensuring compatibility with most drill chucks. This versatility, combined with the superior performance characteristics, makes the Drill America D/A29J-CO-PC 29-Piece Cobalt Drill Bit Set a valuable asset for professionals and hobbyists alike.

The set comes in a specially designed, round drill index that seamlessly combines form and function. This unique case is shatter-proof, water-resistant, and easy to carry, allowing you to take the drill bits wherever you need them. The ergonomic design allows you to effortlessly grip the set in one hand, much like a travel coffee mug, or conveniently store it in the cup holder of your vehicle while en route to the job site. When all hands are on deck, the drill index can be easily hung on your belt, whether you're working in the shop or the field.

In summary, the Drill America D/A29J-CO-PC 29-Piece Cobalt Drill Bit Set is a versatile and high-performance tool that is well-suited for tackling the most demanding drilling challenges. With its exceptional quality, innovative design, and unparalleled convenience, this set is a must-have for any serious workshop or job site.
