15.7mm Tapered hole Water Swivel Chuck with Adapter for half inch Gas Thread

Water Swivels for Core Drills are essential accessories for wet diamond core drilling, providing a constant, pressurized water flow directly through the core bit to flush out debris and cool the drilling surface. Engineered for precision and durability, our wet drilling swivel heads are manufactured with pressure-sealed ball bearings, high-grade stainless steel spindles, and lightweight aluminum bodies, making them ideal for both manual and automated drilling setups.
These precision drilling water swivels fit directly into your drill press or machine spindle, acting as a reliable coolant feed swivel. Water is delivered directly through the center of the sintered diamond core drill, allowing you to achieve clean, chip-free holes in a variety of materials including glass, stone, ceramics, and quartz. This makes them perfect for both glass drilling accessories and industrial stone coring needs. Each water swivel adapter ensures a secure connection to prevent run-out and improve core bit longevity.These 37mm and 40mm Extension Adapters feature both internal and external 1/2" GAS (BSP standard) threads, offering a secure and precise solution for extending the reach of your diamond core drills, water swivels, and other compatible tools.
Manufactured with high-precision machining and corrosion-resistant materials, these adapters ensure tight, leak-free connections and vibration-free operation—perfect for wet core drilling in glass, stone, ceramics, and concrete.
