Bandsaw blade speed

I've always used the higher speed for resawing (18" saw & its about all I do on it).

What would one use the lower speed for?

Actually, the slow speed IS for ferrous metals - steel, cast iron, etc. The slow speed is to reduce heat from friction which will ruin the blade. Of course, you will need a metal cutting blade, and always remember: keep a minimum of two teeth in the metal at all times. This prevents the blade from snagging on the metal and tearing the teeth out. You can cut soft metals like aluminum and brass at the high speed on a band saw though. Actually, you can cut aluminum on a table saw with no problem if the blade has carbide teeth.

Depends on the speeds :)

What saw is it? Once you know what the speeds are for it, you can determine what it is designed for… here is an example found floating around the web:

For the Delta 14" Wood/Metal bandsaw (aka: 28-3xx), here is the speed chart for various materials:

With a bandsaw designed specifically for metal (not combination metal/wood), the blade speeds are typically much lower than one designed for wood. It seems like frequently the higher speed of a metal cutting bandsaw is about the same as the slow speed of a wood cutting bandsaw. That's usually why a wood bandsaw says "non-ferrous metal only"

rwe2156 states he has an 18 inch bandsaw which would not be a table top type. It would obviously be an industrial bandsaw at that size. Many industrial 18 inch bandsaws offer a high speed (wood), low speed (ferrous metals) speed change, usually by an in-out dog like in the (older) larger Delta band saws. You reach beneath the stand to make the change.

How old is that saw? Note item #3 in the second list: "Asbestos, Sheet"
How long since you could get a sheet of asbestos without some sort of a hazardous materials license?

Depends on the speeds :)

"The blade speeds are 1510/3220."

Yep, that's too high a speed for ferrous metal. Sounds like your bandsaw is made only for cutting wood at those speeds. I'm not sure why the two speeds for a wood cutting bandsaw. I did some research on google and most wood recommendations are around 3,000 fpm. which is what I have always used. Couldn't find anything recommended for the 1,500 fpm area. You might call Ricon about this I am curious now.
