What speed when cutting steel with a hole saw??
TVMIA

What kind of hole saw? What type & thickness of steel?
Rule of thumb- slow and with plenty of lubricant to (a) cool and (b) clear
swarf.
If heat becomes a problem, stop. Cool and start again, but slower/more
lubricant.
My magdrill works at about 500rpm fixed speed with constant lubricant. This
can overheat when boring 30mm holes in 20mm plate with new or very good
broach type cutter.

Anyway, it'l depend on the diameter of the saw. Larger diameter, slower
speed. I find slowly and but with reasonably high pressure tends to
avoid overheating, but that again depends on whether the saw's still
sharp.
