Stone Drilling Core Bit 45mm is a premium 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 use, it delivers fast drilling speed, clean hole edges, and excellent precision without cracking or damaging the surface.
Manufactured with industrial-grade diamond segments, this 45mm core bit ensures high durability, heat resistance, and long service life even under continuous heavy-duty applications. 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 installing anchors, plumbing fittings, electrical conduits, pipe openings, 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 45mm diamond core bit is ideal for professional contractors, tile installers, and stone fabricators who require precision, reliability, and smooth drilling performance in every application.
