A quick trip to the big city yielded a nice Milwaukee hammer drill, and a couple of bits.
This unit used what’s called SDS Plus bits. The shank has a long notch in it to aid in it not slipping while rotating (I would guess).
the last time I saw a shank like that was at the Free Clinic!
The drill has hammer and drill, drill only, and hammer only settings with another that allows freewheeling of the chuck.
Variable speed with a lock ON, adjustable side grip handle, and a handy carrying case.
and looky here! It’s got yer Easy Rider Rifle Rack for not one, but three of yer favorite rifles!!!
Plus I got two sacks of quick set concrete, being the optimist that I am..
Every do it your selfer oughta have a hammer drill. If for nothing else, than just to tell your neighbors that you DON’T have one.
