@ SCOTSMAN In general he is incorrect there is nothing about carbide blades that require higher speeds, though many “hobby” saws run well below optimum speed but it doesn’t perevent the use of carbide blades in any way. The real issue is can a particular saw tension the blade high enough (both the blades in question like 28,000-30,000 PSI) AND has wheels large enough to not cause metal fatigue in the band. In the end for many people bi-metal blades offer some of the benefits of carbide without the high buy-in price. The non-set and ground teeth of a carbide blade will in general leave a better finish than most non-carbide blades though.
