29 Piece M42 Cobalt Drill Bit Set in Round Case
GUARANTEED SAFE CHECKOUT
The Drill America D/A29J-CO-PC 29-Piece Cobalt Drill Bit Set is a comprehensive collection of high-quality drill bits designed for drilling tough materials like stainless steel, Inconel, and titanium. This set includes 29 m42 Cobalt Drill Bits ranging in sizes from 1/16" to 1/2" with 1/64" increments. The Cobalt Drills feature a self-centering 135-degree split point that allows for drilling hard materials without the need for a pilot hole, producing smaller chips that reduce clogging compared to traditional 118-degree points.
Manufactured to Aerospace Standard 907, these Cobalt Drills exhibit high red hardness, enabling them to achieve speeds up to 30% faster than conventional M2 high-speed steel drills. The cobalt steel construction provides extended tool life compared to standard high-speed steel bits, ensuring toughness and hardness even in high-temperature drilling conditions. Additionally, a gold oxide finish on the drills acts as a lubricant and enhances wear resistance.
The round shanks of the drill bits allow for compatibility with a wide range of tool holding systems. The set comes in a unique round drill index that combines both form and function, making it easy to carry and use. The shatterproof and water-resistant case is designed for convenience, allowing you to effortlessly grip the set with one hand, similar to a travel coffee mug. You can also store it in the cup holder of your truck while on the go or hang it on your belt when you need quick access to your tools, whether you're in the shop or out in the field.
