Answer summary
What is the Blanco 401735 Quatrus R15 28 Sink Cutout DXF template for?
Blanco 401735 Quatrus R15 28 Sink Cutout is a sink cutouts DXF template for countertop fabrication. Use it only after matching the manufacturer, model, dimensions, variant, and shop workflow to the actual job.
Risk check: Similar-looking products can use different cutout geometry. Confirm the official spec, shop tolerance, material behavior, and CNC output before production.
Next step: Run a DXF check, compare related templates, and keep the current manufacturer spec with the job packet.
Template decision guide
Should you use the Blanco 401735 Quatrus R15 28 Sink Cutout DXF template?
Use the template page to shortlist a production file, then verify the exact model, variant, and machine workflow before cutting.
Best fit
Blanco 401735 Quatrus R15 28 Sink Cutout is most useful when the product, manufacturer, model, install type, and variant match the job you are fabricating.
What to compare
Compare model number, dimensions, reveal or overhang, bowl or appliance geometry, material thickness, and CNC output requirements.
Risk check
Do not use a similar-looking template as a final production file. Small changes in flange, radius, trim, or reveal can cause a failed cutout.
Evidence to verify
Check the current manufacturer spec, field measurement, template preview, DXF layers, and a shop-approved tolerance before production.

The Blanco Quatrus R15 28 delivers professional-grade performance in a compact footprint perfect for smaller kitchens and secondary prep areas. Measuring 28 inches wide with a generous 26x16 inch basin, this single-bowl undermount sink maximizes usable space without sacrificing capacity. German-engineered from premium 18-gauge 304 stainless steel, it features signature 15mm radius corners that blend contemporary styling with practical cleanability. Our production-tested DXF template offers four installation variants tailored for natural stone fabrication, ensuring flawless results whether you're working with granite, quartz, marble, or ultra-compact surfaces. The rear-positioned drain and integrated sound dampening make this an exceptional choice for quality-conscious installers.
Installation Overview
The Quatrus R15 28 fits 30-inch minimum cabinet widths, making it an ideal solution for galley kitchens, condos, and urban spaces where every inch counts. Despite its compact overall dimensions, the 26x16 inch bowl provides surprising capacity - large enough for full-size sheet pans and oversized cookware. Our template collection includes four precision-engineered variants: no-reveal for flush installations creating seamless transitions between sink and stone, 1/8-inch reveal for traditional undermount applications with subtle shadow lines, 1/2-inch overhang for 3cm materials requiring additional support surface, and drop-in configuration for top-mount scenarios. The 18-gauge stainless steel construction delivers exceptional rigidity while pre-installed sound dampening pads minimize operational noise. When templating, note the X-pattern drain grooves molded into the basin floor - these functional channels should align with the client's dishwasher location for optimal workflow. The 15mm radius corners require careful CNC programming to achieve the smooth curve that distinguishes Quatrus from competitive products. Pay attention to the rear drain positioning, which maximizes cabinet storage below and creates additional workspace in the bowl itself.
CNC Cutting Notes
Programming the Quatrus R15 28 cutout demands precision in the corner radii to achieve the signature 15mm (0.625-inch) curves. Use a three-pass strategy for optimal edge quality: roughing at 85% feed rate removes bulk material efficiently, semi-finish at 70% establishes dimensional accuracy, and finish pass at 50% creates polish-ready edges. The 28-inch width sits in a sweet spot for CNC table stability - still compact enough to maintain excellent vacuum hold-down while providing substantial structural integrity during cutting. For corner radii, implement spiral descent toolpaths rather than plunge cuts to minimize entry marks and potential chipping. Reduce feed rate by 25% through corners and enable constant tool engagement algorithms in your CAM software. The stainless steel bowl's tight manufacturing tolerances require equally precise cutouts - target ±0.008-inch accuracy throughout. Polish undermount edges to 600-grit minimum for optimal silicone adhesive bonding and long-term installation integrity. The template's organized layer structure separates reference geometry from actual cut paths, streamlining toolpath generation and reducing programming time significantly.
Material Compatibility
This template excels across the full spectrum of natural and engineered countertop materials. In granite installations, the 28-inch width works beautifully in standard kitchen layouts while the deep 9-inch bowl accommodates serious cooking equipment. Quartzite fabricators should deploy premium diamond tooling rated for ultra-hard materials and increase corner dwell time to prevent micro-fracturing in these demanding stones. The sink pairs excellently with engineered quartz, where the stainless steel's thermal expansion characteristics complement quartz's dimensional stability. Marble installations require special attention to edge distance - maintain minimum 3.5-inch clearances and apply penetrating sealer to cutout edges before mounting. The 9-inch bowl depth functions well in both 2cm and 3cm materials, though 3cm installations provide superior aesthetic proportion and structural support. For ultra-compact surfaces like Dekton, Lapitec, or Neolith, the Quatrus mounting system and weight distribution ensure secure long-term performance. The compact footprint makes this sink particularly valuable in premium marble applications where maximizing stone visibility is critical - you get professional sink capacity without overwhelming the countertop's natural beauty.
