Description
This heavy-duty DXF template provides cutting specifications for large-diameter hot water dispenser installations in commercial and high-capacity residential applications. Featuring an oversized 1.75-inch mounting hole diameter, this template accommodates commercial-grade instant hot water dispensers, specialty high-flow models, and custom installations requiring larger-than-standard penetrations. The generous 5.0-inch clearance zone ensures adequate space for heavy-duty mounting hardware, larger diameter supply lines, and commercial-grade connection assemblies. Fabricators working on restaurant kitchens, commercial food service installations, or luxury residential projects with high-capacity hot water requirements will find this template essential for accommodating the robust hardware and larger shanks typical of commercial dispensers. This template is designed for demanding applications where standard residential hot water dispensers cannot meet the performance requirements.

Installation Overview
Large hot water dispensers requiring the 1.75-inch mounting hole are typically commercial-grade units designed for high-capacity, continuous-use applications. The oversized hole accommodates the larger shank diameters and more substantial mounting hardware found on commercial instant hot water systems. The 5.0-inch clearance diameter indicates the significant unobstructed zone required beneath the countertop for commercial mounting assemblies, multiple supply lines, and potentially larger connection fittings. When planning installations with this template, verify that the commercial-grade dispenser unit is on-site during templating - commercial products have wider specification variations than residential units, and field verification is essential. Position the dispenser for optimal workflow in commercial settings, considering the reach requirements for staff and the relationship to sinks, prep areas, and other equipment. Commercial installations often require reinforced countertop construction, particularly in high-traffic areas or where the dispenser will see frequent heavy use. Verify adequate below-deck clearance for commercial hot water tanks, which are substantially larger than residential units - commercial tanks may require 18-24 inches of vertical clearance and often need dedicated electrical circuits (potentially 220V for high-capacity units). Ensure the installation location provides access to appropriate water supply (often requiring larger than standard 1/4-inch lines for adequate flow) and verify electrical requirements exceed what standard residential outlets provide. Commercial code requirements may mandate specific positioning relative to food prep areas, sinks, and emergency shutoffs.
CNC Cutting Notes
Import this DXF template into your CNC programming software and verify the 1.75-inch hole diameter is correctly scaled - this is a non-standard size that requires specific tooling. For CNC fabrication of this large-diameter hole, you'll need a 1.75-inch (44.5mm) diamond core bit, which is not commonly stocked and may require special ordering. Verify bit availability before scheduling the job. Program the CNC to cut from the finished surface downward to minimize visible edge chipping, which is more challenging with larger diameter holes due to the increased cutting circumference. Set conservative cutting parameters: for granite, use 1.5-2.5 inches per minute feed rate with continuous, high-volume coolant flow - the larger diameter generates more heat and requires enhanced cooling. For engineered quartz, reduce feed rates to 1-2 inches per minute and ensure coolant reaches the entire cutting edge circumference. The larger hole diameter creates more stress on the material during cutting, so slower speeds and increased coolant are essential for clean results. Ensure complete penetration through the material thickness plus 3-4mm for this larger hole size. The 5.0-inch clearance circle is for reference and indicates the substantial keep-clear zone required beneath commercial installations - do not cut this circle. For commercial-grade countertops or extra-thick materials (4cm+), adjust cutting depth accordingly and consider two-stage cutting (partial depth from top, complete from bottom) to prevent core bit binding in thick materials. When working with commercial surfaces that may have steel reinforcement or embedded mesh (some commercial-grade materials), use diamond blades rated for cutting rebar and reduce feed rates significantly. For manual cutting of this large diameter, use a heavy-duty diamond hole saw with pilot bit and consider drilling relief holes around the perimeter before coring to reduce bit stress and improve cooling access.
Material Compatibility
This large hot water dispenser template is designed for use with heavy-duty countertop materials capable of supporting the substantial weight and stress of commercial-grade dispensers. Suitable materials include thick granite (3cm-4cm), engineered quartz (3cm or thicker), commercial-grade solid surface, and reinforced composite materials designed for commercial applications. The 1.75-inch hole diameter is significant and requires adequate material thickness and proper positioning to maintain structural integrity. For standard 3cm materials, position the hole at least 4 inches from any edge, seam, or other penetration, and consider reinforcing the area beneath with steel or epoxy backing plates to prevent flexing under the weight of commercial dispensers and during heavy use. In 2cm materials, this large hole size is generally not recommended unless the material is specifically rated for commercial use and properly reinforced - consult the material manufacturer's specifications regarding maximum penetration sizes for the thickness being used. Commercial installations often use 4cm or custom-thickness materials to provide the necessary structural support for heavy equipment. When cutting this large diameter in natural stone, pay special attention to the stone's natural fissures and weak planes - a 1.75-inch penetration is more likely to intersect natural defects than smaller holes, potentially creating crack propagation points. For ultra-compact surfaces used in commercial settings (Dekton, Neolith), use premium diamond core bits rated for maximum hardness materials and reduce feed rates by 40-50% compared to granite. The larger diameter means more cutting edge contact and proportionally more heat generation, making proper coolant application critical. In materials with directional grain structure (some quartzites, soapstone), orient the cut to minimize crossing grain boundaries where possible. For commercial solid surface installations, the large hole can be cut and the edges routed smooth, but verify with the manufacturer that the material thickness and hole size combination meets their structural specifications for commercial use.
Where to Buy
Large-diameter hot water dispensers requiring the 1.75-inch mounting hole are typically commercial-grade products available through commercial food service equipment suppliers, industrial plumbing distributors, and commercial kitchen design firms. These are not standard residential products and generally require specification by commercial kitchen designers or food service consultants. Potential sources include commercial divisions of major manufacturers, specialized commercial plumbing suppliers, and restaurant equipment dealers. When sourcing products for this template, verify the exact shank diameter and mounting requirements - commercial products often have custom specifications and may require specific installation components. Commercial hot water systems typically include high-capacity tanks (2-5+ gallon capacity), potentially require 220V electrical service, and may need dedicated water supply lines larger than standard residential 1/4-inch tubing. Professional fabricators working on commercial projects should coordinate closely with the mechanical contractor or kitchen equipment supplier to ensure all specifications are confirmed before cutting. Commercial dispensers may be part of integrated systems including filtration, temperature control, and multiple-station distribution, requiring careful planning of below-deck space. Pricing for commercial-grade hot water dispensers varies widely based on capacity and features, typically ranging from $600-$2000+ for the dispenser unit, with commercial tanks and associated equipment adding significantly to the total system cost. For commercial projects, ensure all products meet applicable health department and building code requirements for the jurisdiction. Many commercial kitchen suppliers offer design and specification services to ensure proper equipment selection and installation planning. Given the specialized nature of these products, lead times may be extended compared to residential items - plan accordingly when scheduling fabrication and installation.
