[PSUBS-MAILIST] hole saw

Mon Jul 16 05:50:38 EDT 2018

Hi Hank,

A couple of weeks ago i cut a 50mm hole through 1.5mm galvanised steel
with bi metal hole saw.  It did it, but only just and ruined the saw.
I don't think it will work on 1/4".

What about using a jig saw with HSS blade?  Slow but would probably
work, and the blades are cheap!
