My helper has a tendency to push really hard on the drill when drilling pocket holes in a kreg jig. The next thing I know, all the pocket holes are too deep because he pushed the stop collar down the shaft of the drill bit. Upon finding this out AGAIN this morning, I realized I could cut about 3/4" off the bottom of the drill bit so there was no bit left between the collar and the chuck of the drill. Now there's no way the collar will slide up the bit and make the holes too deep. I used to grind a small flat spot on the bits for the set screw, but there would still be play in that idea if I didn't make the slot deep enough.
Just thought it might help someone with similar problems
