Demo Hammer- Non-rotating chisel bit hammering.
Roto Hammer- Powerful hammer action with rotating drill; often has a switch to put in Demo-hammer mode
Hammer drill- light duty hammering drill action, basically meant for 1/4" holes (blues and screws or nail-drives); will also usually operate as a regular drill.

-Edit- removed the part where I was a dickhead

I am looking for recomendation for good drills for bolting granite. Specific model name/numbers would be helpful so I can try to find one for a good price. Also if you know please let me know the average # of 3/8"x3" holes one battery will drill in granite. EDIT: I am looking for a rotary hammer not hammer drill. I got a hammer drill and tried using it...FAIL! Hahaha. Thanks In Advance!

abatix.com has a variety of power tools and drills that you might try out. They tend to be priced more affordably than some of the other brands out there. Here's a link to some of the power tools to look at: [abatix.com/products/POWER%20TO...

the hidden waterfall
Hi All, Im currently living in a place where there is no rock climbing at all, but have found nice rocks to climb (is in south America not US). Im (or was?)mostly a trad climber so for me, if there is a crack, no bolt will be needed (put this statement so the answers dont get of course).

I have never bolted or open routes but if i want to climb i have to start this en devour. there are no high rocks (would say they range from 8 to 15 mts. max. that is 24 to 45 ft.) and not near each other, so some places that i spotted could get from 2 to 7 routes (of course routes can share bolts). I prefer to climb rather than stay hanged drilling and cleaning and will put the least bolts possible; by I eye i will say 6 holes max. (in the highest rock found)including the ones for rappel (of course it depends on each route).

Will this drill be enough??

How many holes for a single charge if drill is new?? (type of rock: hard granite (you can see by yourselves in the post of original comment) text is the same:
