The Blanco Precis 30 (model 442536) brings professional kitchen sink design to residential applications with its crisp angular lines and SILGRANIT composite construction. This 30-inch single bowl undermount sink takes inspiration from commercial food service while delivering residential-friendly features like scratch resistance, stain protection, and heat tolerance to 536°F. Our precision DXF template provides stone fabricators with accurate cutout dimensions for granite, quartz, marble, and ultra-compact surface installations.

Installation Overview
Installing the Blanco 442536 Precis 30 follows standard undermount procedures with attention to the sink's angular design and SILGRANIT material properties. The sink measures 30 inches wide by 18 inches front-to-back with a 9.5-inch bowl depth—notably deeper than many competitors in this size class. Our template provides four cutout variants optimized for different reveal preferences: no reveal (28.0" x 16.0"), 1/8-inch reveal (27.75" x 15.75"), 1/2-inch overhang (27.0" x 15.0"), and drop-in configuration (30.0" x 18.0"). The no-reveal option creates a flush installation maximizing bowl capacity and delivering ultra-modern aesthetics. The 1/8-inch reveal variant remains most popular among fabricators, providing subtle definition that accommodates minor installation tolerances while maintaining clean lines. The 1/2-inch overhang works well with 2cm stone or when maximum countertop coverage is desired. The sink's 0.25-inch corner radius creates crisp transitions requiring precise CNC cutting—much tighter than traditional rounded corners. Undermount the Precis using high-quality epoxy adhesive or mechanical clips designed for composite sinks. The rear center drain with 3.5-inch opening accommodates standard disposals and basket strainers. Minimum cabinet size is 30 inches though some sources specify 33 inches for optimal fit. The SILGRANIT material's thermal stability eliminates expansion concerns during adhesive curing.
CNC Cutting Notes
CNC cutting the Precis 30 template demands precision due to the tight 0.25-inch corner radius—far smaller than typical kitchen sink cutouts. This sharp transition requires careful tool selection and programming to avoid corner breakout, particularly in brittle materials like quartzite. Use a 1/4-inch or 3/8-inch diamond router bit for the radius cuts with reduced feed rate in the corner zones. For quartz fabrication, employ progressive cutting: rough pass at 1/8-inch clearance, intermediate at 1/16-inch, and final on-line pass with 40% reduced speed through corners. The angular design means you're cutting primarily straight runs with minimal radius work—this actually simplifies programming compared to sinks with large sweeping curves. Maintain continuous water delivery to manage SILGRANIT composite dust and prevent diamond tool glazing. Granite cuts cleanly with sharp tools and standard techniques. The 28-inch bowl dimension (no-reveal variant) provides good material utilization from standard slab sizes. When programming reveal variants, verify the reveal dimension against actual sink measurements as the tight corner radius can make visual inspection difficult. Test corner radius on scrap material first to dial in optimal feed rates and verify the radius matches the sink precisely. For ultra-compact surfaces like Dekton, slow the corner cutting speed further to prevent micro-chipping at the tight transitions.
Material Compatibility
The Blanco Precis 30's SILGRANIT composite construction ensures universal compatibility with all premium countertop materials. Granite installations pair natural stone with composite material sharing similar thermal expansion coefficients, creating stable long-term installations. Quartz and engineered stone complement the Precis 30's contemporary angular aesthetic—the tight corner radii echo quartz's modern design language. The Metallic Gray SILGRANIT finish particularly suits concrete-look quartz patterns popular in urban and industrial-style kitchens. Marble and quartzite installations benefit from SILGRANIT's superior stain and etch resistance compared to the stone itself—you can safely clean the sink with acidic cleaners that would damage marble. The 536°F heat resistance exceeds all countertop materials' thermal tolerances, eliminating differential expansion concerns. Ultra-compact surfaces like Dekton, Neolith, and Lapitec create stunning monochromatic installations when paired with matching gray-toned SILGRANIT. The Precis 30's professional aesthetic suits slab-height backsplashes and waterfall edges common in contemporary design. The sink's composite construction provides excellent cutout edge support, reducing stress concentrations in thinner 2cm installations. Maintain 1.5-inch minimum material around the perimeter for structural integrity, with 2-inch preferred in brittle materials.
Where to Buy
The Blanco 442536 Precis 30 undermount sink is available through kitchen and bath showrooms, plumbing distributors, and online retailers specializing in premium kitchen fixtures. Lowe's, Amazon, Build.com, F.W. Webb, AF Supply, and QualityBath stock the Precis 30 with pricing typically ranging $350-600 depending on SILGRANIT color selection—notably competitive for a German-engineered composite sink. Professional fabricators access trade pricing through regional Blanco distributors and plumbing wholesalers. The Precis line's professional styling makes it popular with designers and architects specifying contemporary kitchens. Available finishes include Metallic Gray (442536), Anthracite, White, and other SILGRANIT colors to coordinate with various countertop palettes. The sink includes Blanco's limited lifetime warranty covering manufacturing defects. Weight is a manageable 42 pounds, simplifying handling during installation. Some retailers bundle the sink with custom-fitted accessories including stainless steel grids, cutting boards, and colanders designed specifically for the Precis 30's rectangular bowl geometry.
