| Reviews | I find Bosch to always be reliable with my tool needs. This bit is useful for steel and metal drilling. It is made of titanium and was sharp and solid. I was putting together a metal base for an outdoor planter system for my wife. I am unable to speak for long term use or for thicker metal drilling but for my needs I felt it was great value and great performance. | Drilling through different materials used to wear out my bits fast. Since switching to the Bosch Hard Core Cobalt drill bit, I’ve saved both time and money. It stays sharp much longer, which means I don’t have to carry multiple bits of the same size for one job—my tool bag is lighter, and I get more done with less. Highly recommended. | I used this to make holes in metal. I'm building my son a metal sword to hang on his wall. This bit is great didn't break or anything. Will be buying more of these cobalt Bosch bits. My son is very happy with the way the sword is coming along. | Nice tough drill bit it do get hot but it with stand the heat nice clean hole not much splinters easy to use very durable bit testing at high speed it held up didn't move I would definitely recommend this but | Quality drill bit at a reasonable price. Great for drilling mild steel, stainless steel and aluminum. Works well in a hand drill as well as a drill press. Highly recommend these bits. Have used these Bosch cobalt bits a from 1/16”-1/2” and all function well. Pull the trigger, these bits are worth it. | This drill bit really works hard for those hard jobs, and gets the job done right the first time, yet is lightweight and doesn't show the wear and tear. Very high quality equipment. Totally recommend 👌. |
