Cobalt Jobber Drill Bits

The 115 pcs high-speed steel with 5% cobalt drill bit set can resist high heat abrasion while drilling. The M35 cobalt HSS twist drill bits are more suitable for hardened working materials, particularly adapted to drilling stainless steel, cast iron, high-temperature alloy, titanium alloy, and even hard plastics and woods. They can also be used for soft materials.

Twist Drill Bits

The premium HSS with 5% Cobalt and 135° split point drill tip design guarantees the 115 pcs drill bits keep their sharpness while drilling hard materials and prevent tips from walking on the working surface. The proper twist and flute design clears chips and particles fast.

Wide Application

The Jefe Hex 115 pcs set with sharp and hard cutting edges is ideal for versatile applications, especially for projects made from hard materials, such as kitchen utensils, machine parts, medical equipment, and DIY projects.

Organized Holder

The whole drill bit set is kept in one iron case with a size index holder for easy storage and organizing.
