ZENESIS™ Obsidian Diamond Core Bit

The ZENESIS™ Obsidian diamond core bit is the ultimate tool for tile and stone, capable of drilling clean holes in porcelain, granite, marble, ceramic, DEKTON®, and quartzite—wet or dry. Exclusive ZENESIS™ pattern diamond segments offer up to 70% longer life, while drop segments add durability and weld protection. Depth gauge lines at 20mm and 30mm improve precision, and brazed diamonds inside and out prevent binding for easy plug removal. Compatible with all grinders and polishers.

Professional Diamond Core Bit for Tile and Stone

The ZENESIS™ Obsidian Diamond Core Bit is a professional-grade, high-performance tool engineered for precision drilling in a wide variety of hard materials, making it an essential asset for tile installers, stone fabricators, and construction professionals. Designed to tackle even the most challenging surfaces, this diamond core bit effortlessly drills clean, accurate holes in porcelain, granite, marble, ceramic, DEKTON®, quartzite, and other engineered or natural stone materials, whether used wet or dry. Its advanced design combines cutting-edge engineering with durable construction to ensure reliable performance, longevity, and efficiency on every project.

Advanced Pattern Diamond Segment Technology

At the heart of the Obsidian Core Bit is ZENESIS™’s exclusive patterned diamond segment technology, which provides up to 70% longer life compared to conventional core bits. The pattern ensures optimal material removal while reducing heat buildup and vibration, delivering smooth, precise drilling with minimal chipping or edge damage. Additionally, drop segments enhance durability and protect the welds from stress during heavy-duty applications, further extending the tool’s lifespan and reliability in demanding fabrication environments.

Precision Depth Control and Smooth Core Removal

Precision and control are built into every detail of the Obsidian Diamond Core Bit. Depth gauge lines at 20mm and 30mm provide quick and accurate visual references for consistent hole depth, reducing the likelihood of overcutting or misalignment. Brazed diamonds both inside and out prevent the bit from binding, allowing for smooth, effortless plug removal and minimizing downtime during repetitive drilling tasks. This thoughtful engineering ensures that every hole is clean, precise, and free from cracks, chips, or surface imperfections.

Versatile Compatibility for Professional Applications

Versatility is another key feature of the Obsidian Core Bit. It is compatible with all grinders and polishers, making it adaptable for a wide range of equipment and fabrication setups. Whether drilling standard holes for plumbing, electrical, or decorative fixtures, or creating intricate patterns in natural stone and engineered surfaces, this core bit delivers professional-grade results with exceptional speed and accuracy.
