The Diamax Diamond Cone is a precision diamond grinding tool designed for expanding, shaping, and smoothing drilled holes in hard materials such as porcelain tile, ultra-compact surfaces (UCS), and granite. Its tapered cone design allows fabricators and installers to easily enlarge small holes created by core bits while maintaining clean edges and accurate hole dimensions. Manufactured with premium brazed diamond technology, the tool delivers aggressive grinding performance while maintaining its original shape throughout its lifespan. This durable diamond coating ensures consistent cutting efficiency and smooth finishes without excessive chipping or cracking of the material. The Diamond Cone can be used wet or dry and is designed with a 5/8″-11 threaded arbor, making it compatible with common tools such as angle grinders and pneumatic machines. This versatility makes it ideal for both fabrication shops and on-site installation work where precision hole enlargement is required.
