Stone Drilling Core Bit 80mm is a heavy-duty diamond drill bit engineered for accurate and efficient drilling in hard materials such as granite, marble, ceramic tiles, porcelain, vitrified tiles, and natural stone. Designed for professional applications, it delivers high drilling speed, clean hole edges, and excellent precision without cracking or damaging the surface.

Manufactured with industrial-grade diamond segments, this 80mm core bit ensures exceptional durability, heat resistance, and long service life even under continuous heavy-duty use. The strong diamond bonding provides stable cutting performance, reduced wear, and consistent results, making it suitable for demanding construction and fabrication environments.

This drill bit is widely used for larger pipe openings, drainage systems, plumbing installations, electrical conduits, and decorative stone applications. It performs best with wet drilling, which helps control heat buildup, improve cutting efficiency, and significantly extend tool life.

Compatible with standard drilling machines and angle grinders (with adapter if required), this 80mm diamond core bit is ideal for professional contractors, tile installers, and stone fabricators who require precision, reliability, and smooth drilling performance in every application.
