Ask. Answer. Discuss. Any bolting related issues.
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.
What is chert? Normal SDS bits should do the trick.
