Title: Good for small tapcons only
Review: This thing is fine for small tapcon screws, but don't try to make big holes in anything hard with it.I had an experience similar to one of the other reviews. I was drilling 5/8ths inch holes in concrete with it. I drilled 2 holes and then the bit started to slip. Tightened up the chuck and it worked a while and then slipped again. I was able to barely finish the job by really jamming the chuck tight every 10 seconds of drilling or so.Now the chuck won't even close, I think it's completely shot. Anyway this drill is great if all you need to do is sink tapcons with a little bit. If you ever want to make big holes, get something else. This thing is liable to give up after only one hole.
