Hey everyone, I’ve been having issues with my band-saw not tracking and decided to look into it. Since researching I’ve managed to find 2 things I should be trying; the first is to get my settings correct on the band-saw – blade location, guides properly tuned, tension set properly. The second is possibly needing a new blade.
I’m offshore at the moment so I decided to research into what I can control now – buying a proper blade. I’ve never bought a band-saw blade before so I couldn’t just go out and purchase straight away. HOWEVER, now I have done quite a bit of looking up and made the tables you see below. It actually seems to be quite straightforward for a hobbyist such as myself.
If you would like much more in-depth knowledge, the best I have found all in one place was at Saw Mill Creek forum.
Take a look at the information below to determine the best blade for you. For those of you that can fill me in on anything missing please leave a comment or drop me an email.
Teeth Per Inch (TPI)
From the table below, find material thickness then use the corresponding TPI value or greater by up to around 2 “levels”. Table was determined based off the need for a minimum of 3 teeth in the material at any time.
Lower TPI = Faster, rougher cut
Higher TPI = Slower, smoother cut

Blade Width
Determine the radius you will be cutting to find the maximum blade width. You should used the widest blade you can keeping in mind the limitations of your saw by consulting your owner’s manual.

If you frequently use your band-saw or blades you will use frequently |
Requires more tension than carbon steel |
Carbide Tipped |
Re-saw work or LOTS of ripping |
Requires more tension than carbon steel |
