Hi all -
not really metalworking but sometimes there's an overlap...
I was looking at some youtube videos and came across this hole-saw with a slug ejector that's one of those forehead slapping 'why didn't I think of this' things...
This is a hole-saw that has a slug ejector with a reverse thread so when you are finished drilling out whatever (drywall, sheet goods, etc.) just reverse the drill and the slug is pushed out.
They have a video demo at but skip all the introductory stuff and go to about 2:16 and see it work.
Only drawback is it appears to use proprietary hole saw cups and maybe not available in a wide variety of sizes.
I have no connection whatsoever with this company, it just looked like a cool product. (video was uploaded in 2011, has had only about 200 views so it may be history by now.)
