Metal step drill

I have a stepped bit for drilling through metal caps, but I can't find an extension tool that fits stepped bits that would allow me to drill though metal cross braces several feet down into a wall cavity. Whenever I encounter horizontal metal bracing, I have to place the outlet above the brace--too high to look good. I'm no good with drywall repair, so what to do?

Do you have any sort of extender for this bit?

I have hex backed hole saws and short (12") extenders. I took an extender to a machine shop and he was able to use the collar with set screw off it on a peice of bar stock (he milled the ends hex) to make me a 6' extender.

Might be possible to take an existing extender and weld on a longer shaft.

Your milage may vary.

Re: Metal step drill

What size is the shank on your step bit?
Here are two extenders that will handle up to 3/8" shanks
