Installing Hardie Plank siding. (Fiber cement combination) Manufacture
states that I should use a special blade. Went to Home Depot, and yes,
they make a special blade. It is simply a carbide tooth blade with with a
total of 6 teeth. 7-1/4 inch diameter.

Can somebody explaing why a six tooth carbide blade would cut any better
than, say, a 24 or 40 tooth blade that I use for lumber? I don't
understand the physics.

Thanks,

The 6 tooth will have a more controlled feed cut and run much cooler. I
don't know what grade the carbide is or tooth style or kerf set. There are
a lot of variable in play and you shouldn't have to do the homework over
again. Use the recommended blade.
