Delta Single Handle Single Hole
Description
Delta single handle faucets represent the most popular and versatile faucet configuration for modern bathrooms and kitchens. These streamlined fixtures combine hot and cold water control in one lever, requiring only a single mounting hole in the countertop or sink deck. Our DXF template provides exact specifications for Delta single handle installations, featuring a 1.375-inch diameter hole that accommodates the faucet body and mounting hardware. This template works across Delta's extensive single handle product line, including bathroom lavatory faucets, kitchen prep faucets, and bar sink models. The single-hole configuration simplifies installation, reduces countertop penetrations, and creates a clean, contemporary aesthetic. For fabricators, this template is optimized for CNC routers, bridge saws, and core drilling equipment, compatible with granite, quartz, marble, solid surface, laminate, and other countertop materials. The template can also be used with optional deck plates for 3-hole sink conversions, providing flexibility for various installation scenarios.

Installation Overview
Installing a Delta single handle faucet begins with precise hole placement during countertop fabrication or sink preparation. The single 1.375-inch diameter hole must be positioned to align with the sink basin and provide adequate clearance to the backsplash. For bathroom installations, typical placement is centered 2 to 4 inches behind the front edge of the countertop, though this varies based on sink bowl size and shape. Kitchen installations often position the hole further back to accommodate larger sink basins and provide comfortable operating angles. The faucet includes a plastic or rubber gasket that seats against the top surface, with mounting hardware that secures from below through the single hole. Maximum deck thickness for most Delta single handle models is 1.5 to 2 inches, covering standard residential and commercial applications. After hole cutting, edges should be smoothed and sealed to prevent moisture intrusion. The faucet's supply lines connect beneath the deck to hot and cold water supplies, typically using 3/8-inch compression fittings or 1/2-inch IPS connections. For 3-hole sink configurations, Delta provides optional deck plates (escutcheons) that cover the unused holes while using the center hole for faucet mounting. This adapter feature allows single handle faucets to retrofit into existing 3-hole setups without countertop replacement.
CNC Cutting Notes
When programming CNC equipment for Delta single handle faucet holes, set the tool path for a 1.375-inch finished diameter (0.6875-inch radius). Use climb milling direction to minimize top-surface chipping, especially important for polished stone or high-gloss materials. For granite and engineered quartz, select appropriate diamond-grit core bits—typically 30-40 grit for cutting and 100-200 grit for edge polishing. Reduce feed rates when approaching breakthrough to prevent bottom-surface blowout or cracking. Position the hole centerline parallel to the sink's front edge, maintaining consistent spacing from the backsplash per the design specifications. Standard bathroom installations place the hole 2 to 4 inches from the front deck edge, while kitchen applications may vary from 2 to 8 inches depending on sink depth. Apply masking tape to the cutting area before routing to protect finished surfaces and contain debris. For waterjet cutting, adjust abrasive flow and pressure to prevent edge microcracking in brittle materials. When cutting laminate countertops, use backer boards beneath the cut zone to prevent bottom-layer delamination and ensure clean through-cuts. For solid surface materials, standard carbide router bits work effectively at moderate speeds, though coolant or compressed air helps prevent heat buildup and melting. Verify hole position relative to sink bowl geometry before cutting—particularly for undermount installations where the hole must clear the sink mounting clips and rim. The template coordinates use the hole center as the origin point (0,0) for easy alignment with CAD drawings and sink cutout files.
Material Compatibility
The Delta single handle faucet template is universally compatible with all countertop materials commonly used in residential and commercial installations. Natural granite cuts cleanly with diamond core bits and adequate water cooling, producing smooth edges that require minimal polishing. Marble requires gentler cutting approaches due to its relative softness and tendency toward edge chipping, benefiting from slower feed rates and sharp tooling. Engineered quartz materials like Silestone, Caesarstone, and Cambria demand high-quality diamond or carbide tools with continuous cooling to prevent resin scorching and ensure clean edges. Solid surface materials including Corian, Hi-Macs, and Avonite machine easily with standard carbide bits but require attention to speed settings to avoid friction melting. Laminate countertops use carbide-tipped hole saws with backer support to prevent delamination, followed by edge sealing to protect the particle board core. Porcelain slabs require specialized diamond core bits and patient cutting due to extreme material hardness, but produce excellent results with proper technique. Concrete countertops should be fully cured before drilling, with care taken to avoid reinforcement mesh or fiber additives in the hole location. Soapstone is soft and cuts easily but can be brittle around hole perimeters, requiring gentle handling and sharp tools. Wood and butcher block countertops use standard hole saws with pilot holes and backer boards to prevent tearout. Stainless steel and metal countertops require bi-metal hole saws or step drill bits designed for metal cutting. Regardless of material, all hole edges must be appropriately finished—polished for stone, sealed for laminate and wood, deburred for metal—to ensure long-term durability and professional appearance.
Where to Buy
