Why customers choose TaskHolt Tools

Engineered for hard metals and stainless steel

Drill Hulk 3/16-inch cobalt steel twist drill bits deliver steady performance when drilling through tough materials. The blend of high-speed steel with 5% cobalt raises red hardness, helping the edge resist wear and maintain sharpness under heat. This means you can work through stainless steel and other hard alloys with more confidence and fewer interruptions.

Designed with a jobber length and a 3-flat shank, these bits offer a balanced feel in standard drill chucks and reduce the risk of slipping under pressure. The 2-5/16 inch flute length and 3-1/2 inch overall length provide enough reach for common metalworking tasks, while the 135 degree split point helps start holes cleanly without wandering.

Key specifications

  • Diameter: 3/16 inch; flute length: 2-5/16 inch; overall length: 3-1/2 inch
  • 5% cobalt in high-speed steel boosts heat resistance and edge durability
  • Uniform hardness allows reliable re-sharpening without edge damage
  • Applications: drilling in hard metals and stainless steel
  • Includes: 12 pieces in a protective case

What you gain with this set:

  • Quieter, smoother starts and reduced wandering thanks to the split point
  • Consistent performance across repeated sharpening sessions, extending tool life
  • A practical, portable solution for metalworking tasks
  • A sturdy, organized case that helps keep your workshop neat and ready

Real-world use cases

In metal fabrication, automotive repair, or home workshop projects, these cobalt bits can handle stainless steel components, enclosures, or brackets that demand durable cutting edges. The clean starts and steady cutting help you maintain accuracy while you work through tough alloys.

Why choose Drill Hulk

These bits strike a balance between hard-wearing construction and practical design. The cobalt composition targets higher heat resistance, while the standard jobber length and 3-flat shank pair well with a wide range of drills. The 12-piece pack is ready for ongoing projects or shared toolbox use.
