Review on 🔧 Bosch CO14B PC Cobalt Drill: Versatile and Powerful Precision Tool by Byron Howell

I tried to drill a drywall screw, but the 1/4 inch drill didn't go through the screw. I called Bosch and they told me the drywall screws were too hard for these drills. I drilled a few holes in an aluminum rod about 1/4" thick with no problems other than a drywall screw! This was my last Bosch purchase. I admit the rep I spoke to was nice, he let me make that one Stopping work to find out why these bits wouldn't drill through a drywall screw.I was told to use a black onyx bit because of the hardness of the screw.C'mon GYPSKBON SCREW.Next time I'll just go to the port and buy a cheap drill and throw them away like Bosch bits!
