Drilling/breaking Bedrock. Best SDS and Bits?

[Quinc]

Hey all, trying to widen the road to my mining claim and there is a knuckle of bedrock that is around 15" thick and 5-6' tall. Trying to coming up with ideas on how to deal with it and thinking I can drill holes into/threw it every few inches then bust it out with a sledge. Looking for some advice on which 20v SDS Dewalt hammer drill and bits to get? Any other tips for busting bed rock would be very much appreciated as well. =)

Carbide tips and some water

dexpan might help.

Picked up this hammer drill and a few different stone bits. I also got some Dexpan. Wish me luck. =)

I can't really say what bit would be ideal for a percussive electric drill, as I've only dealt with the larger pneumatic and hydraulic rock drills. If I had to choose something for an electric drill I think this Bosch xtrem design looks good. The carbide design looks very similar to what's used in hardrock mining with a pneumatic jackleg drill.

drilled a bunch of holes and then used a 15ton hydrolic press to break off the knuckle. Worked well. I will post some video up at some point of it. =)

I ended up making my own sierra blaster and that is by far the easiest way to make big rocks into little rocks. =)
