Preventing drill bit slippage
I am using a 1/2" masonry bit in an old hammer-drill. At the slightest
catch, the bit slips, even to the point of coming out. It uses the old screw thing to tighten. I am thinking of grinding the bit up and down the bare spot. Any other ideas? John |

Who woulda thought... :-) Problem solved. I asked a friend and he told me to just grind a little bit off three sides of the shank of the masonry bit. I did; it ground like butter. And when the bit grabbed the material, it threw me against the wall. Success! John |
