SPC: Stone plastic Composite. It's about 1/2" thick and very dense and stiff.

Just wondering what you used to cut it with? Manufacturer (Cortec) recommends masonry blades, which to me means diamond blades, is that the way to go? Wondering if standard carbide blades will work (Knowing the blade will be useless for anything else afterwards) or maybe blades intended for fiber cement? In any case I'll be using a portable circ saw as the tool, and sabre saw where needed. Tiles are 18 x 24.
