 Post subject: bolting in chert
PostPosted: Sat Sep 24, 2005 5:04 pm 
i'm wanting to bolt some routes in the bluff we have at the camp i work at. the darn thing is chert - super hard rock. i've been told it will chew up any type of bit; it's probably crumbly, too. anyway, i'm looking for some tips on how to go about this. thanks.

Contact Alan Jarvis: Alan.Jarvis@ReedHycalog.com. He knows a lot about drilling holes in rock.

What is chert? Normal SDS bits should do the trick.
