The Cyclone Ultra Core Bit is designed for use with angle grinders and pneumatic machines, making it suitable for drilling through engineered stone, granite, marble, porcelain, quartzite, and ultra-compact materials. This core bit can be used for both wet and dry applications. Its specific grit and bond composition ensures fast, clean holes, particularly in porcelain and other ultra-compact materials. The thin beveled segments allow for easy entry into the material, and the shortened overall length provides added control during drilling. Its a reliable tool for precision work in challenging materials.
