Drill question

I just came across a Stihl BT 45 wood boring drill http://www.stihlusa.com/products/augers ... l/bt45wbd/. Was wondering if this would be sufficient for drilling into some rock with the right bit?

You're not serious, right? If you are, then no offense, but you have no business even thinking about bolting.

it is ideal for occasional use in building or repairing wooden docks, bulkheads, fences, retaining walls and other structures where electricity simply does not exist.
The key word is WOOD. It is not designed for rock.

It won't work. For rock, you need a bolt gun.

Which brand of bolt gun do you suggest? Is this a good deal?

"and with an optional kit, the BT 45 can be used as a core drill for concrete work"

i think you're being seduced by the size of the bit. amps are usually a more important detail, and in harder rock you may need a hammer drill. i am at the back of the line of people who should comment on this though. (i'd also add that you need sufficient power to get a clean straight hole to make the bolt of any use, right? so power is imp.)

Wood drills spin. Hammer drills spin and vibrate causing a jack hammer effect. Hammer drill is the only way to drill through masonry or rock.
