Review on π§ Top-Notch Performance: Bosch CO2159 Cobalt Drill Bit for Ultimate Precision by Dave Rasic
Snaps cleanly with minimal torque.
Maybe others were lucky and mine broke on the first hole. Did it through 1/4" steel at a relatively slow speed and once it broke through the bit tightened slightly and the bit sheared off halfway down the shank. I would write to the seller but the rush to return is one Spending $15 on this drill expect the same result so take it easy once the material is removed I never thought a 1/2" drill could shear off so easily with minimal torque can, but nowadays anything is possible.
Pros
- Best for drilling light metal, high carbon steel, aluminum and alloys, cast iron, stainless steel and titanium
Cons
- There are other interesting options.
