The XCORES from Rotozip allows for fast, clean cuts in even the hardest materials, such as granite and porcelain. XCORES can cut tile, stone and granite countertops up to 1-1/4 inches thick. The company’s proprietary manufacturing process allows XCORES to withstand extreme heat, lasting four times longer than competitors. In fact, users can cut more than 100 holes with an XCORE in grade 5 through-body porcelain. Links:
