12mm Shaft Water Swivel Chuck with G1/2'' Thread

Water Swivels are essential accessories for wet diamond core drilling, designed to provide a constant, pressurized water flow directly through the center of the core bit. This cooling action flushes out debris, prevents overheating, and ensures clean, chip-free holes in hard materials like glass, stone, ceramics, and quartz.
Built for precision and durability, our water swivels feature pressure-sealed ball bearings, high-grade stainless steel shafts, and lightweight aluminum bodies, making them suitable for both manual and automated drilling setups.
