Locking Nuts
 

Having had my wheels off quite a bit with those drill things, the locking nut has gone to ****, I cant get it off and done fancie drilling it.. I've heard of a tool that digs into the metal to allow you to remove it.. any ideas?

Or you could hammer a socket over it, if there space and use a wrench.

Personally always use hand tools to remove and replace nuts, locking nuts I use are McGards, very tough.

Then torque them to 65lbft
