Cutting Backer Board

[N A T]

I'm thinking of getting a Makita 4 tipped specialised circular saw blade for cutting 12mm hardy board with my 18v saw , has anyone any experience or thoughts with this ?

Frankly I use the standard 115mm diamond tile cutting blade on an angle grinder, coupled with a dust mask. But only for angled cuts, all straight cuts with carbide tipped hardibacker cutter.

Call me (an-l) looking for clean crisp cuts , these always turn out chewed rough cuts , was wondering wether with a skil saw would produce this ?

It depends on the person wielding the grinder. My cuts are very clean, not totally precise, but then I always tile on top of backer boards.
