I bought some of James Hardie Trim made of fiber cement and I'm wondering what the best option is for cutting it is. Home Depot refuses to cut it because it ruins their saw blades.
Scoring this stuff on the back like you do the thin cement board isn't going to give me a clean cut. I saw they make 8 tooth carbide saw blades but don't want to fork over the cash if they don't last more than a few cuts. Was also thinking of trying the disposable fiber-reinforced abrasive wheels but this cement might chew that up pretty fast.
Any real comparative experience between these methods?
