Does any one know if there is anyone making drilling rigs that are designed to work either on a 3 point hitch using the PTO or mounting to a backhoe and using the tractor hydraulics ? The application being drilling in rock not general post hole digging

I checked the Bobcat site as I thought they would be most likely to have such equipment. They have a breaker but not a drill.
Most of these are air driven as there is a lot of abrasive dust generated, even with water cooling and muck extraction.

As Peters mentioned, rock drills are pneumatic powered, not hydraulic, since the hammer action would 1) be slower with hydraulic friction, and 2) cause an excessive heat problem. As for mounting, since VERY few machines have 3pth down-pressure this would be a problem, with backhoe mounted units the wear & tear on all the bushings would be a serious concern, even if the unit was vibration dampened. I have seen some pneumatic drills towed behind tractors, but usually it is pulled by a low, wide track machine because of the terrain normally encountered in this sort of work. Best of luck. ....

I don't know what the application is, but rock drilling sounds like a lot of work and tractor wear and tear. Up here on the Canadian Shield, many people live virtually on bedrock. You sometimes see fences where small rock cairns are built around the posts if they can't be set far enough into soil. We built two cairns this summer where my auger wouldn't get through some fill for an old highway bed. Building a residential structure on bedrock could present a problem under the codes here. You can't use slab on grade or pier foundations for residential use. I believe that piers are OK for recreational buildings. I guess a rock drill might be handy for pier foundations, but a problem might be that water doesn't drain out of most bore-holes. The pier ends likely would be sitting permanently in water. Some of this might be interesting, but I'm aware that I haven't contributed to the original question about rock drills. Well, Murf and Peters are hard acts to follow. ....

My suggestion is to get a good hammer drill. They are expensive. I have had two light ones (up to 1 inch hole. One Hilti the other Porter and Cable. The hilti is superior but 2x price.
Drill 1/2 inch holes in the rock and then bond your reinforcing rods into the rock. Hilti has bonding compound but I would use the gray 2 part epoxi putty.
For concrete forms I would use the Arxx system from Cobourge Ont. Cut your forms to conform to the bed rock and then seal them using urethene foam (Windlock)
You could hire some one to build it. I might consider it? How big a structure?

Note on Hammer Drills: If you are doing a lot of holes, you want a ROTARY HAMMER, not a Hammer Drill. They look the same, and are used for the same types of things, but a rotary hammer is a much heavier-duty tool, and more effective in rock (either seems to work OK in concrete). Rotary Hammer has much harder percussion , though not as rapid (generally) a hammer drill is basically a drill with a "vibrator" built in ... usually faster blows, but lighter.
I unfortunately found this out AFTER buying a cordless hammer drill (nice unit, but a bit slow in harder rock... though it's about 1/3 - 1/4 the price of a cordless rotary hammer) ....

Rotary hammer is the only way to deal with boring rock in very small projects. Retired from 40 years in heavy construction, I've been around rock drilling a few times. A rock drill operates on high volume air, water isn't used in just about all cases as the bit is hollow and air blows through it all the time keeping the hole clean. It's an expensive and heavy operation using about $100,000.00 worth of equipment, not something for the home handy man. Just my 2 cents. PJ ....
