The Vortex Diamond VTXMax J-Slot diamond blade is designed to precisely cut porcelain, ceramic tiles and similar materials. The thin rim greatly improves cutting performance and results in the best cut very time. The design of J-Slot is used for cooling the blade and removing dust/slurry, which greatly improves cutting performance. The core is made from heat-treated hi-speed steel and is guaranteed to withstand the demands of cutting extremely hard tile. The blade can be used for both wet cut and dry cut. Wet cut provides a better performance.
