I found a great rule of thumb in Cutting Tool Engineering for selecting the correct band saw blade. It's the rule of 3, 6, 12, 24. You want at least three teeth on the work all the time, you don't want more than 24 teeth on the work at any one time, and what you would like is between 6 and 12 teeth on the work all the time.

Our bench-top band saw has two speeds. Use low speed for steel and other harder materials. Use high speed for aluminum and other non-ferrous metals. High speed works well for wood and plastic, too.

Bandsaw blades come in two styles.

Constant Pitch	All teeth on the blade have uniform spacing, gullet depth and rake angle throughout the full length. Typically for general purpose cutting. Identified by one pitch number.
Variable Pitch	Size of tooth and depth of gullet varies to substantially reduce noise levels and vibrations. Cuts all structurals, tubing and solids smoothly and quickly. Identified by two pitch numbers.

Here's how the rule of thumb plays out with these blades. Choose a coarser pitch if the speed of cut is most important. Choose a finer pitch if finish is most important.

Blade Pitch	Material Thickness
	Min	Optimum	Max
24	0.13	0.25 - 0.50	1.00
18	0.17	0.33 - 0.67	1.33
14	0.21	0.43 - 0.86	1.71
10	0.30	0.60 - 1.20	2.40
14-18	0.19	0.38 - 0.75	1.50
10-14	0.25	0.50 - 1.00	2.00
