Use this calculator for High Speed Speed (HSS) cold saw blades ONLY.
Do not use this calculator for carbide tipped saw blades. 

At ColdSawShop.com, the question we get asked the most is, "What number of teeth do I need for my application?" When we get this question, we go through a list of questions with the customer to narrow down the exact parameters of their application, including your machine make and model, blade size needed, the material to be cut, the size, shape, and all dimensions of the application.  

We have developed this easy-to-use colds saw blade calculator to make things much easier for you. You must answer each question to get the appropriate number of teeth for your application.  

If you are cutting more than one shape or size of material, it is usually okay to just take the average of two or three different applications. The only time that is not okay is if you have an outlier or extreme circumstance. If you get tooth counts of 100, 140, and 300, then 300 would be an outlier, and it would not be wise to take the average of these three to get the best blade for all three. In this situation, it is best to use one blade for the applications needing 100 and 140 teeth by taking the average of the two to get 120 teeth so you can use this one cold saw blade for the two applications efficiently.

We also have easy to read charts in PDF form available. Just contact us by phone or email and we will be happy to email one over to you!

Select Your Blade Diameter
Please note that while this calculator is helpful, it may not provide a perfect tooth count for your needs. Although it asks for the material you are cutting, it does not take that information into account for the final calculation. However, the output number is safe to use for carbon steel. If you plan on cutting something harder or softer, please reach out to us for assistance in finding the best blade and tooth count for your specific application. We ask for the material you are cutting so that we can determine the appropriate number of teeth needed for the blade, as different materials have varying levels of abrasiveness and hardness.


For example, if you are cutting aluminum, simply multiply the calculation by 0.75 to get the correct number of teeth for your chosen shape and size.
