Blanco 517170 Precis 33 Double Sink Cutout
Description
The Blanco Precis 33 Double (model 517170) delivers professional-grade performance for high-volume kitchens requiring separate prep and cleaning zones. This 33-inch by 18-inch double bowl configuration features equal-sized basins crafted from Blanco's premium Silgranit composite material, providing exceptional durability that outlasts traditional stainless steel. Our precision DXF templates include four installation variants optimized for different fabrication scenarios: no reveal for direct-bond applications, 1/8-inch reveal for standard undermount installations, 1/2-inch overhang for laminate substrates, and drop-in configuration for retrofit projects. Each template incorporates the sink's distinctive 0.75-inch corner radii and has been dimensionally verified to ensure accurate CNC cutting and trouble-free installation across all countertop materials.

The Blanco Precis 33 Double (model 517170) delivers professional-grade performance for high-volume kitchens requiring separate prep and cleaning zones. This 33-inch by 18-inch double bowl configuration features equal-sized basins crafted from Blanco's premium Silgranit composite material, providing exceptional durability that outlasts traditional stainless steel. Our precision DXF templates include four installation variants optimized for different fabrication scenarios: no reveal for direct-bond applications, 1/8-inch reveal for standard undermount installations, 1/2-inch overhang for laminate substrates, and drop-in configuration for retrofit projects.

Installation Overview
Professional installation of the Blanco 517170 Precis 33 Double requires precise attention to cutout dimensions and adequate cabinet support for the dual-basin configuration. This sink necessitates a minimum 36-inch cabinet width, providing sufficient space for the 33-inch overall dimension plus structural reinforcement beneath the basin divider. Fabricators should select the appropriate reveal variant based on countertop material and installation requirements. The no-reveal option cuts to the exact 31-inch by 16-inch bowl opening, ideal for direct bonding with color-matched adhesives in solid surface applications. The standard 1/8-inch reveal variant at 30.75 inches by 15.75 inches represents the industry preference for granite and quartz installations, providing adequate lip support while allowing proper epoxy coverage. The 1/2-inch overhang variant measures 30 inches by 15 inches, distributing weight across maximum substrate area for laminate or thin-stone applications. For drop-in installations, the full-dimension variant at 33 inches by 18 inches accommodates the complete sink rim. The equal double bowl design with center divider requires special consideration during adhesive application to ensure even support distribution.
CNC Cutting Notes
Programming your CNC router for the Blanco 517170 demands attention to the dual-basin geometry and precise corner radii execution. The 0.75-inch corner radii on both basins require a finishing bit diameter of 0.5 inches or smaller to prevent over-cutting rounded corners. For optimal results with granite and engineered stone, implement a three-pass cutting strategy: roughing pass at 100% speed with 0.5-inch bit depth, semi-finishing pass at 80% speed, and final finishing pass at 60% speed using a premium diamond bit. The center divider area between the two basins is particularly critical since any dimensional error here affects both bowl alignments simultaneously. Establish your zero reference point at the sink centerline to maintain symmetrical basin positioning. The double bowl configuration increases total cutout perimeter length, so plan for extended cutting time and ensure adequate bit cooling to prevent heat buildup. Post-cutting edge preparation should reach 220-grit minimum polish for proper adhesive bonding with Silgranit's composite rim material.
Material Compatibility
The Blanco 517170 Precis 33 Double demonstrates excellent compatibility across all major countertop materials with proper installation technique adaptation. Granite and quartzite installations perform best with the 1/8-inch reveal variant, providing structural support while accommodating the natural stone's irregular undersurface texture. The Silgranit rim material bonds exceptionally well with standard granite epoxies when cutout edges are properly polished. Quartz and engineered stone fabricators should ensure mirror-smooth cutout edges since these materials create aggressive mechanical bonds with modern adhesive systems. The equal double bowl design distributes weight evenly, making it suitable for 2cm quartz installations when properly supported. Solid surface materials pair beautifully with the no-reveal variant, enabling color-matched seaming that creates integrated basin appearances. Laminate countertops require the 1/2-inch overhang variant to distribute the sink's weight across sufficient particleboard substrate, with additional bracing recommended beneath the center divider. Ultra-compact surfaces like Dekton work well with the 1/8-inch reveal using specialized non-porous adhesives.
