Classicpro 230mm Professional Turbo Reinforced Blade. These ultra-thin Reinforced turbo blades are our fastest cutting discs for hard materials such as porcelain tiles.Ultra-thin, (1.8mm at cutting edge) for fast cutting and low waste.
I needed to cut porcelain 20mm thick slabs to fit around brick piers, this disc does the job. Can cut dry in a well ventilated area or keep the slab wet a spray bottle works well. I can't comment on its life expectancy as I have only cut 2 slabs to date.
