Description
This precision DXF template provides the exact hole pattern for InSinkErator soap dispensers and instant hot water dispensers requiring a 1.75-inch diameter mounting hole. Designed for professional stone fabricators installing InSinkErator products, this template ensures accurate hole placement for granite, quartz, marble, and engineered stone countertops. The 1.75-inch hole size accommodates InSinkErator's larger mounting hardware and provides clearance for both traditional soap dispensers and their popular instant hot water dispenser systems. This larger diameter offers enhanced stability and easier installation compared to standard 1.375-inch holes.

Installation Overview
The InSinkErator dispenser template features a single 1.75-inch diameter hole, which is designed specifically for InSinkErator's line of countertop-mounted accessories including soap dispensers and instant hot water taps. While standard soap dispensers typically use 1.375-inch holes, InSinkErator's products often require this larger 1.75-inch opening to accommodate their robust mounting systems and larger dispenser spouts. This hole size is particularly common for InSinkErator's instant hot water dispensers which require additional clearance for insulated components and safety features. When positioning this template, place the dispenser 6-9 inches from the faucet center to provide comfortable access without crowding the primary faucet area. For installations combining an InSinkErator hot water dispenser with a standard faucet, consider placing the hot water dispenser on the opposite side of the sink for balanced aesthetics. The template accommodates countertop thicknesses from 1 to 2 inches, typical of both 2cm and 3cm stone fabrication.
CNC Cutting Notes
Program your CNC machine for a single 1.75-inch (44.45mm) diameter through-hole using a diamond-grit hole saw or core bit appropriate for the material hardness. The larger diameter requires more cutting time and generates more heat than standard holes, making proper cooling essential. For granite and quartzite, maintain spindle speeds between 700-1000 RPM with continuous high-volume water flow to prevent thermal cracking and achieve clean edges. The increased hole size removes more material, creating higher stress on both the cutting tool and the surrounding stone - pre-drill a pilot hole to ensure accurate centering and reduce bit deflection. For quartz and engineered materials, reduce feed rates to prevent resin burning and discoloration around the cut edge. Apply wide masking tape (2-inch minimum) on both surfaces to minimize chipping during entry and exit. Consider using a spiral cutting pattern rather than a straight plunge to reduce stress concentration in brittle materials.
Material Compatibility
This template is compatible with all natural stone and engineered countertop materials including granite, marble, quartzite, soapstone, limestone, quartz composites (Caesarstone, Silestone, Cambria, Hanstone), solid surface (Corian, Staron, Hi-Macs), and ultra-compact surfaces (Dekton, Neolith, Lapitec). The 1.75-inch hole diameter is specifically designed for InSinkErator products but can also accommodate oversized soap dispensers from other manufacturers that require larger mounting holes. Due to the increased hole size, reinforcement is strongly recommended for 2cm materials and essential for fragile stones like marble, particularly in high-stress areas near sink cutouts or slab edges. Apply epoxy-bonded fiberglass mesh to the underside of the countertop in a 6-inch radius around the planned hole location before cutting. The larger opening provides better weight distribution for heavy dispenser units, reducing long-term stress on the stone.
