Review on Bosch CO2137 3 1 Cobalt Drill: Superior Performance and Versatility by Richard Lamptey

Revainrating 1 out of 5

Fur. Titanium nitride worked better.

Not suitable for drilling in hardened steel. I'm not sure if my app was boring or wrong. Switched to a titanium nitride bit and it worked like a charm.

Pros
  • Rigid, heavy gauge construction improves bit stability in tough conditions.
Cons
  • Expensive.
