This Q-Drive 10″ Combination Blade is used with the iQTS244 for dry cutting a variety of ceramics, as well as most porcelain, marble, granite and stone. The Cool Cut Technology combined with the built-in vacuum on the iQTS244 keeps the blade cool while cutting. The Q-Drive Arbor hole with the included bushing also fits a standard 5/8″ arbor. For added versatility, it will fit a 1″ round blade shaft when used without the bushing.
