View Full Version : Band saw blade thickness

09-07-2010, 12:23 PM
I have an old 14" Delta band saw. Enco has Irwin Cobalt blades on sale for $32 but they are 0.035" Is that too thick for a 14" band saw?

BTW What brands of blades do you use?

Alex - Yes, too thick. The problem with thick blades on small wheels is they are prone to fatigue failures. The thinner blade may also use a bit less power; a plus for small bandsaws like your Delta and my Powermatic.

The .035 would probably work, but you might as well stick with the .025 or so thickness your saw wants. I buy bimetal blades from McMaster. Their prices are decent (probably less than $32 for a variable pitch bimetal for your saw) and shipping comes to little since I'll add it in with another order. Since the Delta has a more common blade size, you might find closeouts, Ebay deals, etc.

I have been running only 0.035" thick blades on my Delta band saw for years. I use Starrett brand blades and silver solder them with a lap joint. No problems.

I am only concern with the blade fatigue.
I have 2 HP motor on my band saw. The motor produces more then enough torque to handle a thick blade.

I've successfully run .035 blades, TIG welded together, on my 4x6 horizontal only because I got the blade stock free. Not saying it's good practice but it can work.

Here's what I found:

4-6 inches .014"
6-8 inches .018"
8-11 inches .020"
11-18 inches .025"
18-24 inches .032"
24-30 inches .035"
30 inches and over .042", .050", .063"
