What are the specific uses for each?
I hear slower is best for soft stones such as opal. Anything else?
Is faster speed better for some rocks?
I'm using steady speed for preforming; don't have a variable speed.
Thanks.

Is that all there is to know about the advantages of speed (of saws)?

I like to keep the RPM of the blade constant within manufacturers spec. But I have set up variable feed rate systems. Step pulleys let you do this with belts. I have used a blinker circuit on my autofeed motor to limit feed rate.

Well one thing I think is that different blades are designed to be run at different RPMs, so you have to take that into account. Mine are mostly fixed speed, but my one variable speed I always run at max speed anyway.  (I'm assuming you're talking about RPMs versus feed rate). |

Very thin blades need high speed to be stiff enough to cut. MK/BD 303C, 303S and 301 blades work better a little faster than the old blade seed charts said. Most trim saws with belt drive can be set up and run at one speed. Barranca Diamond has a good blade speed chart on their website.
