Stone Drilling Core Bit 15mm is a high-performance diamond drill bit designed for accurate and efficient drilling in hard materials such as granite, marble, ceramic tiles, porcelain, vitrified tiles, and natural stone. It delivers excellent drilling speed, precision, and clean hole finishing without cracking or damaging the surface.
Manufactured with industrial-grade diamond segments, this 15mm core bit ensures high durability, heat resistance, and long service life even under continuous professional use. The strong diamond bonding provides stable cutting performance and reduced wear, making it suitable for demanding construction and stone fabrication applications.
This drill bit is widely used for installing anchors, fixtures, plumbing fittings, electrical conduits, and decorative stone applications. It performs best with wet drilling, which helps reduce heat buildup, improve cutting efficiency, and extend tool life significantly.
Compatible with standard drilling machines and angle grinders (with adapter if required), this 15mm diamond core bit is ideal for professional contractors, tile installers, and stone fabricators who require precision, reliability, and smooth drilling performance in every application.
