I was looking for an SDS Punch, mainly used to install Gripcons & Tapcons. I've probably only drilled 20 1/4" or smaller holes with it, but this thing is great. It's narrowed down to this or the Bosch Bulldog, but I wanted to be able to drill into concrete walls. and only use one hand , as I do a lot of basement repairs and usually 1x hold the strapping with my other hand while I drill it and the concrete.I used to use another SDS drill and I have an old non-SDS impact drill but I think it does now only used for mixing grout etc. This is a good compact SDS drill.
