Stone Drilling Core Bit 110mm is a high-performance diamond drill bit engineered for large-diameter, precision drilling in hard materials such as granite, marble, ceramic tiles, porcelain, vitrified tiles, and natural stone. Designed for professional applications, it delivers powerful drilling performance, clean hole edges, and excellent accuracy even on dense and thick surfaces.

Manufactured with industrial-grade diamond segments, this 110mm core bit ensures exceptional durability, heat resistance, and long service life 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 commonly used for large pipe openings, drainage systems, ventilation holes, plumbing installations, 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 110mm diamond core bit is ideal for professional contractors, tile installers, and stone fabricators who require precision, reliability, and smooth drilling performance in large-hole applications.
