I'm trying to make a special gasket out high density foam rubber. Actually
I'm using a kid's 4oz practice hockey puck as the blank. It's 1" thick and I
need to make a 1" hole in it's center. Does anyone know of type of bit or
other type of cutter that would make a clean cut. The common bits and step
bits just rip it up.



Don't know for sure if this would work,
but:

Put a 1" hole saw bit on a drill press
or press punch and *push* it through
without drilling.
