I recently purchased the thickness planer #23378. I am using it to plane plastic cutting boards made out of "UHMW". My problem is that the blades that come with it do not last for more than six cutting boards before I must reverse the blades. This will get rather expensive having to replace the blades so many times just to finish the order. (I have over a hundred to plane down). My question is: can I purchase blades that are made out of a stronger material that will endure this material? And if so, where? Thanks, Jeff.
