The thinner a blade gets, the quieter it cuts, the less sawdust it produces, and the less power it takes to cut. This lower resistance means that it makes underpowered saws far more efficient. Total Saw Solutions of Wisconsin has come out with the thinnest kerf blade being offered these days with the Micro-Kerf 40 blade. How thin? To coin a phrase, one thin dime — which, according to the U.S. Mint, is 1.35mm, or about .0531". The 10" 40-tooth blade benefits from a built-in stiffener/damper that helps reduce vibration.
The carbide teeth can be resharpened between 10 and 15 times. The blade sells for about $175, in 2011. Because regular splitters wouldn’t work with such a thin-kerf blade, the company offers a splitter set, which can be mounted directly to any zero-clearance throat plate. The splitter goes for around $20 a set, as of 2011.
