Review on 🔧 Bosch CO14B PC Cobalt Drill: Versatile and Powerful Precision Tool by Matt Bokil

Worst of all, two of these drills, the largest and the third largest, each used less than 1/2 dozen times, are ripped out. The bases of both in this location are so rounded that they can no longer even be held in a drill. This is a regular Cal Hawk 10" drill bit and I have not used the larger drill bits for drilling anything other than mild steel. by a relatively soft material. And then I find out that Bosch only gives a 30-day guarantee on these ultra-high-quality drills! Now I have to buy a brand new set of bits and they won't be Bosch.
