Review on Bosch 🔩 CO2139 3-in-1 Cobalt Drill by Bryan Gilliam

3/16 in. x 3-1/2 in. I used a Bosch cobalt drill bit in a hand drill. Circumstances suck because my rechargeable drill died and won't turn on. Most likely, the battery needs to be replaced. Whatever the hand or electric drill, the Bosch CO2139 product probably won't need to be replaced for a good, long time. It's an attractive piece of metal that goes well with my drill. The bit dug into wood and drywall well, I didn't try metal surfaces or anything harder because of the handicap. But I am sure that I can order other Bosch drills.
