Mistake Proofing.
Mistake Proofing.
(OP)
I work in aerospace industry. Obviously we do A LOT of drilling and riveting. My question is that we have a high reject rate for Counter sinks being the incorrect size. Are there any tools/devisces that would mistake proof the drill bit(s) to where it would virtually impossible to drill a bad "countersink"?





RE: Mistake Proofing.
Are these holes being done with a hand drill or a drill press type setup?
A drill press can easily be setup to only drill to a certain depth. Set that and your Csinks will all be the same.
A hand drill/movable unit you can maybe setup a collar that would only allow the bit to go so deep.

Maybe something like the Jack Rabbit.
