jeweler's saws...
Trick with the saws is one, use some stick lubricant on the blade. It'll help it not bind up so much, specially in copper (head gaskets). 2) make sure the clamps on top and bottom are tight. Nothing like a blade going loose in the middle of the cut to cause one to spew oaths! Then, pick the right blade for the work. Thin work wants a blade with smaller teeth. And finally, if you use these on steel, unless it's dead soft, you will replace them often!
Based on many years experience with same, and have been wanting to make one that has swiveling blade-clamps that lock up solid. Maybe someday I'll have enough energy to concentrate well for long periods more than two days in a week.
Otherwise, the best way to make holes quick is a Harbor Fr(e)ight
hole punch, one of those with replaceable punches and dies. They're easy to customise. Trouble is, if you use them a lot, they will get sloppy and horrible. Lathe Time! New pins, ream out
the sloppy holes, button-head screws, and a zerk fitting or two.
