Description
The Venom Grey Blind-Hole Non-Coring Diamond Drill Bit is engineered for fast, clean, and controlled drilling when a complete core removal is not required. This professional-grade non-coring bit grinds a flat-bottom blind hole instead of producing a plug, making it ideal for hardware mounting, countertop anchors, brackets, support pins, clips, and specialty fabrication.
The Venom Grey features a hybrid diamond structure designed for both wet and dry drilling. It runs extremely stable on quartz, granite, quartzite, porcelain, ceramic tile, marble, and engineered stone. Its wide diamond exposure provides fast material removal while maintaining a smooth drilling footprint.
The non-coring design delivers cleaner bottoms, reduces walking during start-up, and prevents chipping on brittle materials. For installers, fabricators, and shop-based drilling, the Venom Grey offers a reliable solution for precision blind-hole applications.
