Is there a 7.25 saw blade that would useful for getting smooth cut edges ?
Asked by greg March 13, 2021Yes, a masonry blade will do just that. BUT, it will create an incredible amount of dust! You must wear a dusk mask and goggles, and cut outside.

I can understand your frustration with this slower cutting method, but once you try cutting Hardie board with a masonry blade and see the volume of dust it creates, you might have second thoughts.

Asked by Jewelz February 28, 2021I would not recommend using this without some other structure to support it.

I am able to bend and break the 1/4 board with my hands.
