When drilling into concrete a hammer drill or rotary hammer is a must. An ordinary drill with a masonry bit will just spin and spin and spin until your arm gets too tired to hold the drill up, then you’ll have to stop and drink a glass of water or something. A Hammer drill is not only drill, they have a miniature jack hammer built in, so they drill through concrete and cement like it is white pine. Hammer drills are also nice because you can switch between an ordinary drill (without the hammer function) or a hammer drill with the flip of a switch which gives it added functionality as it can be used like a regular drill when required.

I have owned this unit for about 6 years now and it has held up well under use. It seems a little stiff to turn by hand, but then again, perhaps that is normal. It is geared pretty low and has plenty of torque.

The Bosch 1194AVSRK drill is a 1/2 inch standard (keyed) chuck drill. It has plenty of power for all jobs and makes quick work of any masonry drilling up to 1/2 inch sized bits. For larger sized masonry holes, there are a few choices. Bosch makes several SDS drills which use special SDS masonry core drills. These work like conventional hole saws, only they are made for masonry work. Or, you can do what I did last summer when I installed the new well pump, I used a hammer and chisel to knock a 2 inch hole in the side of the cinder block foundation. Unfortunately for me, somebody filled the cinder block cells with what looked like 4000 PSI concrete and it took some doing to get the hole all the way through the wall.

Anyway, having the hammer drill around makes light work any masonry drilling needed.
