rbwen Posted March 15, 2006 Share Posted March 15, 2006 Got your attention? I just stumbled across a masonry drilling company that has a bin full of old granite scraps of all sizes. They are perfectly flat, about 1" thick, shiny on one side and grainy/aggregate on the other with great edges for an indoor rock wall hold. Problem is I just spent 45 minutes drilling and only made it through 2/3 of one piece! Is there a quicker way of getting through granite? I started using my cordless Makita but then switched to the plug-in power drill until I couldn't hold it any longer. Ouch. I'm using a masonry bit right now. Tips? If anyone's interested in where the scraps are (my wife grabbed a bunch for her garden) it's downtown Wenatchee on the corner of Yakima and Columbia St. They had pieces as big as two feet long by one foot wide.

markd Posted March 15, 2006 Share Posted March 15, 2006 are you using a rotohammer drill? it would be hard to drill through granite without one. Quote Link to comment Share on other sites More sharing options...
rbwen Posted March 15, 2006 Author Share Posted March 15, 2006 I'm not. I'd never even really heard of one. Just Googled one up to see what you're talking about. Wonder if I can rent one? The guy I talked to at the shop said he could drill some holes for me so maybe I'll take some pieces back and see what he charges. He's a climber too so maybe he'll do it for cheap!

ken4ord Posted March 15, 2006 Share Posted March 15, 2006 They will probably break if they are only 1" thick. Good luck. Quote Link to comment Share on other sites More sharing options...
corvallisclimb Posted March 15, 2006 Share Posted March 15, 2006 the proper drill for drilling granite would be a rotory hammer drill such as the "bosch anihilator" other than that by hand would be the way to go Quote Link to comment Share on other sites More sharing options...
rbwen Posted March 15, 2006 Author Share Posted March 15, 2006 Thanks for all the advice. A buddy of mine has loaned me a rotary hammer drill to do the task at hand. rbwen Quote Link to comment Share on other sites More sharing options...
archenemy Posted March 15, 2006 Share Posted March 15, 2006 Where are the scraps to be found? Quote Link to comment Share on other sites More sharing options...
slaphappy Posted March 15, 2006 Share Posted March 15, 2006 A hammer drill and a roto-hammer are two completely different drills. When the hammer drill doesn't work as expected go rent a roto-hammer from HD and it will cut your work time to nothing. - Quote Link to comment Share on other sites More sharing options...
rbwen Posted March 15, 2006 Author Share Posted March 15, 2006 Scraps are in downtown Wenatchee on the corner of Yakima and Columbia St. There's an apple bin half-full of them and a dumpster with some more right next to it. I can't remember the name of the shop but it's on a dead end street on the southeast side of the intersection. rbwen Quote Link to comment Share on other sites More sharing options...
archenemy Posted March 15, 2006 Share Posted March 15, 2006 Thank you!! I have a roto-hammer you can borrow if you really need it. I used it to set wall anchors in concrete, but I blew the tip out so you would need to buy another tip. Hammer works tho. Quote Link to comment Share on other sites More sharing options...
