Diamax Cyclone S QZT Core Bit Series

The Diamax Cyclone S QZT Core Bit series is a professional diamond core drilling solution designed for quartz and other hard stone materials commonly used in stone fabrication and installation.

Built with a durable steel body and diamond-brazed cutting surface, these core bits are engineered to provide controlled drilling performance in dense materials such as quartz, quartzite, and granite. The hollow core design allows for efficient material removal, making it suitable for drilling holes for plumbing, fixtures, anchors, and hardware installations.

Each bit in the series features a standard 5/8″-11 thread, allowing compatibility with a wide range of professional tools. The Cyclone S QZT Core Bits are suitable for wet or dry applications, though wet use is recommended to help manage heat and maintain consistent performance.

This variant group includes multiple diameter options to accommodate different installation and fabrication needs.
