SMART CUT® Water Swivel Adapters, also known as drill head assemblies, are precision-engineered components essential for delivering a continuous, pressurized flow of water, coolant, or air directly through the center of your diamond core drills and other hollow-shaft rotary tools. This internal coolant delivery method provides direct lubrication at the cutting interface, ensuring the most effective heat dissipation and friction reduction where it matters most—at the point of contact between the tool and the material. By channeling coolant through the core of the tool, these adapters help maintain stable cutting temperatures, reduce thermal expansion, and significantly minimize the risk of cracking, delamination, burning, and tool loading. This results in dramatically extended tool life—in some in many cases over 350% +—as well as faster drilling speeds, reduced downtime, and superior material finish and dimensional accuracy. The integration of SMART CUT® Water Swivel Adapters into your operation will substantially enhance process efficiency and consistency, particularly when working with heat-sensitive, brittle, or high-precision materials. Universally compatible, these adapters are designed to seamlessly fit a wide range of drilling systems, CNC machines, manual drill presses, and automated drilling equipment. They are available in multiple shaft diameters, thread types, and mounting configurations, and are engineered to mate precisely with diamond drill collets and chuck systems.
