Okay, so I have a 1/2” Irwin hand brace drill bit, bored some really handsome holes, went to put 1/2” carriage bolts through them and could barely pound them thru they were soooo tight. i really couldnt elongate them with the brace bit so pulled out the Dewalt and bored them out with a brad bit. Am i missing something fundamental here??

thanks, hk

Herman there may be a few reasons to this. One if the bits have been sharpened incorrectly on the outside of the leading edge of the screw, the size has changed. An auger bit doesn’t leave the walls of the hole as clean as some other bits, this could cause your problems as well. Put a mic on the screw then the bit and see if there is a difference.
