How Many Teeth Do I Need on My Cold Saw Blade?

Most blades we sell are “made to order,” and here’s why.
 
When selecting the best cold saw blade for your application, this is the number one, and most important question you should be asking yourself. How many teeth do I need on my cold saw blade? Selecting the optimal number of teeth for your application will deliver you the best performance and blade life. Typically you want 2 to 4 teeth in your material at all times.
  

Now, this is not the ONLY thing to consider other than diameter of the blade and the arbor hole, pin holes, etc. You also need to consider the rake and relief angle (which is different for stainless, mild steel, aluminum, etc), the coating, and the raw material the blade is made out of, etc...but we will cover that in another post. For now, we will talk about number of teeth.


A common question we get is, “I need a 315mm blade to cut stainless, what is the best cold saw blade for me?” Well, that depends! First of all, are you cutting 16 gauge wall x 1 inch round pipes or are you cutting 3 x 3 x 1/4” wall square tubes? How many teeth we recommend for each of these two applications is going to be polar opposites!
 

  • 16 gauge x 1 inch round pipe - 300 teeth
  • 1/4 inch wall x 3 x 3 square tubes - 120 teeth
 

 
If you were to use the 300 tooth blade on the 3 x 3 x 1/4” wall tube you would have a bad time. The blade would take a really long time to get through and dull quickly. Conversely, if you used the 120 to cut the thinner 16 gauge material you would experience a lot of dented tubing and maybe even broken teeth on your blade from the teeth catching on your material.
 
While we do have our Tooth Calculator available to use on our website, we also offer free handouts for each size blade from 250mm to 450mm with handy charts showing the various number of teeth recommended for each application at a glance. Email or call us anytime and we would be happy to email you a copy for your reference.
