Drilling Rocks

[ikon]

is there a specific type of REAL rock that you can drill a hole through without cracking the rock? id imagine there are some that will simply split with that much pressure being applied.

a small core drill will do the trick on any rock. you need quite abeefy drill though.

but granet, though this is very hard, most green slate, with a decent thickness, will take a hammer drill. any rock that is taken from the sea, lol cant think a hammer drill will bash as hard as the sea will, damp sand makes a good shockproofing vice, you need a big pile though.

A few(i mean a lot)of masonary bits, a drill press and water for lubing the bit, and many hours of light drilling should do it.

Slate drills pretty easily, I put holes in it with a regular drill & masonary bit, then screw it to driftwood.

if you can get some diamond tipped drill bits, they aint cheap but they will work alot better against the rock

Dont forget to lube and cool the bit as much as possible as you go - it'll get pretty hot !

You can use a masonry bit on any rock, as long as you use the right speed it should be ok. If it gets hot, try putting some 3 in one oil in the hole then continue drilling.

If its taking ages to get through, use the hammer drill function on the drill....

they use a mix of water and castor oil....
