Cobalt Jobber Drill Bits

This set features high-speed steel (HSS) drill bits infused with 5% cobalt, providing exceptional resistance to high heat and wear during drilling. The M35 cobalt HSS twist drill bits are specifically designed for tough materials, making them perfect for drilling stainless steel, cast iron, high-temperature alloys, titanium alloys, and even dense plastics and woods. They can also be effectively used on softer substrates.

Twist Drill Bit Design

Crafted from premium HSS with a 5% cobalt composition, the drill bits boast a 135° split point design to maintain sharpness while drilling through hard materials. This design also prevents the drill tips from walking across the surface, enhancing accuracy. The proper twist and flute design facilitates rapid clearing of chips and debris.

The Jefe Hex 115-piece set is equipped with sharp, resilient cutting edges, making it invaluable for a wide range of applications, particularly projects involving hard materials. Ideal for use in crafting kitchen utensils, machine components, medical devices, DIY projects, and more, these drill bits can handle various tasks with ease.
