I have a couple of small sets. It's true that if the bolt or screw is heavily rusted or corroded in place, they aren't much help other than drilling a hole. But every now and then you run across a bolt or screw that snapped in tension and the top portion loosens up and falls out, leaving you with a stud half way down in the threaded hole.
Combine that with a transverse engine that sits 4 inches away from a uni-body sub-frame, and a left hand bit in a 90° angle drill can be your best friend sometimes. Especially if it keeps you from having to remove the engine to access the broken bolt location with a straight drill.
No chance at all with a RH twist drill though.
