I would like to find a rpm chart for cutting steel with a hole saw. Anyone
know of such a creature? For example I have one two inch hole to make
in some
plate steel. A slow rpm but how slow? Thanks! Scott

I have just such a chart from a Blu-Mol "The Aggressor" Bi-Metal 3.5" hole
saw. I put it aside when I opened it last week, thinking it might be
useful someday--looks like someday has arrived rather soon. Here are the
recommended RPM settings:

Mild Steel: 95
Tool & Stainless Steel: 45
Cast Iron: 65
Brass: 130
Aluminum: 145
Max RPM: 750
