The Kohler K-6666-AG Wellspring is a premium filtered cold water dispenser designed to work seamlessly with Kohler's Aquifer filtration systems. This professional-grade DXF template provides countertop fabricators with the exact 1.375-inch diameter hole specification required for flawless installation in natural stone, engineered quartz, and solid surface countertops. Our CNC-ready template ensures precise positioning and eliminates costly errors during the fabrication process, delivering the quality results that discerning homeowners and designers expect from Kohler fixtures.
Installation Overview
The K-6666-AG requires a single 1.375-inch (1-3/8") diameter hole drilled through the countertop surface for installation. This elegant beverage faucet features a single lever handle with 360-degree swivel spout, standing 8-13/16" tall with a 4-15/16" spout reach from center. The unit delivers 1.5 gallons per minute and is designed for single-hole deck mounting. Fabricators should position the hole with adequate clearance from sinks and backsplashes—maintain at least 2 inches from the rear edge and 4-5 inches from adjacent fixtures to allow comfortable lever operation. The dispenser is reverse osmosis compatible and works with Kohler's under-counter Aquifer filtration cartridges (sold separately). When planning multi-fixture installations, account for the spout's swivel radius to prevent interference with adjacent faucets or appliances.
CNC Cutting Notes
This template is engineered for precision CNC router cutting and diamond core drilling operations. For CNC fabrication, program the center point coordinates and utilize a 1.375" diameter bit with incremental depth passes of 0.100"-0.125" to prevent material stress cracking. Optimal spindle speeds for engineered quartz are 14,000-18,000 RPM with continuous water cooling for heat dissipation and dust control. For natural granite and quartzite, reduce speeds to 10,000-14,000 RPM and increase water flow. Fabricators using diamond core drill methods should mark the template's center point with precision and drill perpendicular to the surface, advancing slowly through the final pass to prevent bottom-surface chipping. The template includes industry-standard tolerance specifications (+/- 0.002") to ensure proper fit across all Kohler dispenser models.
Material Compatibility
This countertop template delivers professional results across all major surface materials used in residential and commercial fabrication. It is fully compatible with natural stones including granite, marble, quartzite, limestone, and soapstone, as well as engineered quartz brands such as Caesarstone, Silestone, Cambria, HanStone, Viatera, and MSI Q. Solid surface materials (Corian, Staron, Hi-Macs, Avonite) and ultra-compact surfaces (Dekton, Neolith, Lapitec) are equally supported. The standard 1.375" diameter perfectly accommodates the K-6666-AG's mounting hardware and compression gasket, which creates a watertight seal across varying surface finishes including polished, honed, leathered, and textured. For laminate countertops, use plywood reinforcement around the cutout perimeter and employ climb-cutting techniques to prevent delamination and ensure clean edges.
