Review on Cobalt Jobber Length Drilling Metal: Unleash Precision and Efficiency by Craig Lovro

Revainrating 5 out of 5

These pieces of cobalt are brittle and break easily.

These drills are designed to break the handles of traditional dinner forks and spoons and broke six jets in eight holes.I've used many DeWalt and Milwaukee cobalt jets with no problems.It may be factory seconds or I just have a bad batch but I don't recommend them.

Pros
  • ✔️ COBALT DRILL SIZE: 7/64" (diameter) x 1-1/2" (groove length) x 2-5/8" (overall length)
Cons
  • Crumpled Packet
