The Cyclone Reverse CNC Non-Core bit with water hole, 1/2″ gas, is a precision diamond drilling accessory engineered for detailed CNC machining tasks and wet or dry drilling applications on hard surface materials such as granite, engineered stone, quartz, marble, and porcelain. This specialized non-core bit delivers controlled, clean holes with enhanced cooling thanks to its integrated water hole design, making it ideal for stone fabrication, plumbing holes, anchor inserts, and other precision drilling operations. Key Features: Integrated Water Hole: A built-in water hole allows coolant to reach the cutting interface directly, improving cooling efficiency, reducing heat buildup, and significantly extending the life of the bit. 1/2″ Gas Thread Connection: A standard half-gas threaded shank ensures secure and stable attachment to CNC machines, hand drills, and compatible drill systems. Versatile Wet or Dry Use: Designed to perform effectively in both wet and dry drilling environments, with water cooling recommended for optimal performance and bit longevity. Applications: Reinforcement hole drilling in countertops and slabs Precision holes for plumbing, fixtures, anchors, and fasteners Detailed CNC machining tasks where clean edges and controlled drilling are essential Specifications: Material Compatibility: Granite, engineered stone, marble, quartz, porcelain Fitting: 1/2″ gas male thread Integrated Cooling: Water hole for enhanced cutting performance This Cyclone Reverse CNC Non-Corebit combines precision engineering and enhanced cooling features to deliver clean, reliable drilling performance in professional stone fabrication and CNC operations.
