I am purchasing a new saw blade for my 8″ table saw and am trying to decide between the Forrest WWII 30T vs 40T. What I am looking for is the 8″ equivalent of their 40T 10″ blade for general use with hardwoods. Based on the number of teeth per inch of cutting edge, the 30T 8″ would be the same as the 40T 10″ (1.27 teeth/in); but I don’t know if, in practical application it scales down directly like that (that is the heart of my question). I would appreciate any help in this selection. (And yes, I know there are a lot of other great blades out there but I’ve settled on the Forrest. I just don’ t know if tooth count scales directly with blade diameter.
Thanks,
Lance

I would go for the lower tooth number (30). Can't think of a reason why, in practice, it would not make sense. Especially since an 8" saw is likely to be a bit underpowered and be less happy about driving all those theeth through the wood.
I would also go wtih the 30 T in your case. I prefer 40 T to cross-cut and 20 T to rip on my 5 HP 10" saw but.. I believe on an 8" saw 40 T would produce very fine cross-cuts but you would give up too muchj efficiency ripping. If you examine what you do most I bet personally it would be ripping by a far larger % over cross-cutting. :>)
Good luck...
Why not a phone call to Forrest and ask them. They seem to know what they are doing!
I think it is 800-733-7111 Sorry if I am wrong.. I tend to transpose numbers. Just my brain!
Call Forrest and discuss it with them. They are very helpful.
I'am not going to do the math. But tip speed is part of your answer. Number of teeth passing a given point in a minute.
