This drill did an excellent job of what I bought it for, drilling 7 clean holes in plaster and plaster wire in about seven minutes . Round old working electrical boxes fit perfectly. Whether I'll ever use it again is irrelevant compared to the hammer and chisel alternative. I used it with a base Makita 18V with a hammer setting. The only issue I had was the quick release of the spike - I haven't tried removing it yet, but even if the price per hole went up $2 it's fine. Don't forget that you need a carbide drill.
