Broke a brand new auger bit on a frost line in Vermont last Tuesday

I was digging post holes up near Burlington and hit a rock shelf about 18 inches down. Snapped the tip right off my 12 inch bit on the third hole. Had to switch to a manual digging bar and a shovel for the rest of the afternoon. Anybody have a go-to brand for bits that can handle rocky ground?

Try Bosch Daredevil bits. They handle rocky ground and frost lines way better.

Oh man, you are so right about those! I grabbed a set of Bosch Daredevils last spring and they cut through this nasty limestone layer on my property like it was nothing. Before that I was snapping regular bits left and right, but these just chew right through. @the_joseph nailed it with that recommendation. I even used them to dig a post hole in January when the ground was half frozen and they didn't slow down one bit.
