Blanco 516321 Precis 27 Single Sink Cutout
Description
The Blanco 516321 Precis 27 Single optimizes bowl capacity within the compact 27-inch overall footprint that fits perfectly in standard 30-inch base cabinets common throughout North American residential construction. This SILGRANIT composite sink delivers the generous 24-inch x 15.5-inch bowl dimensions that accommodate full-size dinner plates and cookware while leaving adequate counter space on both sides for food prep and landing areas. Countertop fabricators appreciate the Precis 27's balanced proportions and subtle 0.75-inch corner radii that simplify template programming while maintaining the contemporary rectangular aesthetic clients demand. Our precision DXF template package includes four installation variants calibrated for different reveal preferences, ensuring reliable fitment across granite, quartz, and solid surface applications where undermount installation delivers the clean lines this sink design deserves.

Installation Overview
The 27-inch sink category represents the smallest practical single bowl configuration for primary kitchen cleanup tasks, making proper installation critical to maximize the available bowl capacity. The 516321 Precis 27 requires a minimum 30-inch cabinet base, the most common dimension in production and semi-custom cabinetry lines, providing adequate support for the 9.5-inch deep bowl without compromising structural integrity. Template positioning should center the sink within the cabinet opening unless specific design requirements dictate offset placement for adjacent appliances or specialized work zones. The four template variants provide installation flexibility across different fabrication approaches and client preferences. Standard undermount installations achieve optimal results with the 1/8-inch reveal variant which creates a subtle visible ledge accommodating normal cutting tolerances while maintaining the clean undermount aesthetic. The no-reveal option suits installations where the countertop edge meets directly at the bowl rim, though this demands exceptional cutting precision and perfect sink positioning during installation. Use the 1/2-inch reveal variant when design intent calls for pronounced ledge visibility or when working with materials where larger reveals provide better structural support. The drop-in variant contradicts this sink's design intent and should only be specified when undermount installation is genuinely impossible due to material or structural constraints.
CNC Cutting Notes
Programming CNC toolpaths for the Precis 27's clean rectangular profile with rounded corners follows standard sink cutting procedures, making it an excellent template for shops new to sink cutout fabrication. Begin by roughing out the interior bowl area with a series of stepped depth cuts, leaving material tabs at strategic points to maintain slab rigidity throughout the cutting process. Follow with perimeter finishing passes that include the 0.75-inch corner radii, programming smooth G2/G3 arc interpolation rather than linear segment approximations to achieve the fluid corner transitions the design requires. Standard 10mm or 12mm diamond router bits handle the corner radii without requiring specialized small-diameter tooling. Set feed rates at 120-150 inches per minute on straight sections when cutting granite or engineered quartz, reducing to 80-100 inches per minute through corner transitions to maintain consistent surface finish quality. The 24-inch bowl width represents moderate material removal compared to larger sinks, allowing faster overall cutting times while still requiring attention to cut sequencing that balances material removal across the cutout perimeter. Maintain continuous coolant flow throughout the cutting process to prevent heat buildup that can discolor cut edges or create thermal stress in the surrounding material.
Material Compatibility
The Blanco 516321 Precis 27 integrates seamlessly with premium countertop materials where its SILGRANIT composite construction provides durability that complements natural stone and engineered surfaces. Undermount installation in granite and engineered quartz works best with the 1/8-inch reveal variant, creating the subtle shadow line that enhances visual depth while accommodating the fabrication tolerances typical in production environments. Minimum countertop thickness is 2cm for undermount applications, though 3cm material delivers superior structural performance and enables more refined edge profile options around the sink cutout. The sink weighs approximately 25-30 pounds, requiring adequate cabinet structure and properly positioned mounting clips to distribute the load evenly around the bowl perimeter. In solid surface installations, the non-porous SILGRANIT material creates visual interest through material contrast, though successful integration requires thoughtful color coordination since the materials exhibit different tonal characteristics and light reflectance properties. The 9.5-inch bowl depth necessitates verification of clearance beneath the countertop to accommodate the bowl extension plus mounting hardware and plumbing connections. Avoid specification in laminate countertops since this sink is engineered exclusively for undermount installation where the bowl rim attaches to the underside of solid substrate materials.
Where to Buy
The Blanco 516321 Precis 27 Single is available through authorized kitchen and bath retailers including Ferguson, The Sink Boutique, Riverbend Home, DirectSinks, and specialty plumbing suppliers serving residential and commercial markets. Typical retail pricing ranges from $320-$480 depending on SILGRANIT color selection and retailer promotional programs. The 516321 model number designates a specific color finish within the Precis 27 family, with Blanco using different SKUs for identical sinks in alternative colors including Anthracite, Coal Black, Metallic Gray, White, Cafe Brown, and Soft White. Verify the model number corresponds to your intended finish specification when placing orders to avoid color mismatches during installation. Professional countertop fabricators may qualify for trade pricing through Ferguson's professional division, local plumbing wholesalers, or direct Blanco dealer programs offering volume discounts and priority allocation during supply constraints. Some retailers bundle sinks with matching accessories including bottom grids, cutting boards, and rinse baskets engineered specifically for Precis 27 bowl dimensions, providing value packages that enhance functionality. All Blanco SILGRANIT sinks include comprehensive limited lifetime warranties covering manufacturing defects, material degradation, and finish integrity under normal residential use conditions.
