I have a craftsman drill, 1/2 inch chuck, turns 400 RPM. It gets used about four or five times per week. It has never failed me. Lives in the trailer with most of my other construction tools. The kicker is I bought it in 68 I think. In those days sears had as good a tools as any one. I still buy all craftsman hand tools, prefer them over snap on and the rest. I have never had a problem returning any tool to sears. You do have to insist on a new replacement, they will try to give you a remanufactured or repaired ratchet. I have even taken back bars and ratchets where you could clearly see the marks from the presuader and never questioned.
