The M14 Diamond Max tile drill bit is designed for drilling precise holes in extremely hard materials such as porcelain, gres, quarry tiles, cast iron and fibreglass. It features an M14 thread that fits directly onto an angle grinder, or can be used with adaptors for spot polishers and die grinders. Designed for dry use, it requires no cooling while delivering clean and accurate holes without perimeter scratches. The high-grade diamond bond and tough alloy body provide superior durability and long service life, while multiple access slots allow for easy slug removal. The drill bits are available in a wide range of sizes from 5 mm to 102 mm, with set options and adaptors also available for added versatility.
