Bosch 11245EVS Rotary Hammer Drill

Some drilling action in solid New Hanpshire rock. This type of rock is very hard to drill and break . I had to bring the depth of the trench about a foot down for the boiler main pipes. Please check out the rest of the video of the Eko Wood Gasification Boiler Project

A regular pneumatic rock drill will drill a 38mm hole 600mm deep in hard Granite in 75 seconds when used by a seasoned operator.

Why not just wear pajamas?

That would have to be the dumbest thing I've seen for a while. I have one of those Bosche impact hammer drills. And that's exactly what they are used for, getting through a barrier. For breaking up large areas use a demolition hammer with a point.
On the other hand were you going to put a stick of TNT and blow it up? :)

If I am not mistaken I see that you used dexpan for this job, did it worked finally?

This isnt a hammer drill, its a rotary hammer drill which you would use for drilling holes in concrete or masonry. Its obvious why he was drilling holes and not using a demo hammer as you can see with the bucket just to the right of him.
