Answer summary
What is the Blanco 440067 Diamond 1-3/4 Reverse Sink Cutout DXF template for?
Blanco 440067 Diamond 1-3/4 Reverse 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 440067 Diamond 1-3/4 Reverse 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 440067 Diamond 1-3/4 Reverse 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 440067 Performa Cascade delivers contemporary Metallic Gray SILGRANIT finish with the innovative cascade ledge design. This 32x19.5-inch undermount sink features an offset dual-depth configuration: a spacious 21.5-inch left bowl with full 10-inch depth for heavy-duty washing, paired with an 8-inch right section at 7.75-inch depth for the integrated drying and draining platform. Our precision-engineered DXF template provides granite and quartz fabricators with manufacturer-verified cutout specifications across four installation variants. The sophisticated Metallic Gray finish complements both modern and traditional kitchen designs, offering a versatile alternative to standard white or black composite sinks. Each template variant ensures accurate CNC programming and professional installation results.
Installation Overview
Installing the 440067 Performa Cascade requires understanding the offset bowl layout and cascade functionality. The sink's 32-inch width and 19.5-inch depth fit standard 36-inch base cabinets with adequate side clearance for structural support. The 30x17.5-inch interior divides into functional zones via the cascade ledge: a 21.5-inch wide left bowl for washing cookware and dishes, and an 8-inch right section designed for the included mesh colander and air-drying. The left bowl's 10-inch depth accommodates stockpots and large roasting pans, while the right section's 7.75-inch platform sits elevated above the basin floor for optimal drainage. Undermount installation utilizes clips on the 1.5-inch rim combined with silicone adhesive bonding to the countertop underside. Critical installation details include positioning the 3.5-inch drain in the deeper left bowl, offset toward the rear to avoid interfering with the cascade ledge functionality. The Metallic Gray finish offers a neutral tone that hides water spots better than white while providing warmth compared to darker colors. At 40 pounds empty weight, ensure cabinet structure includes proper bracing to support the sink plus operational loads.
CNC Cutting Notes
CNC programming for the 440067 utilizes the standard 30x17.5-inch interior bowl dimensions that define all Performa Cascade cutting variants. Our no-reveal template cuts precisely to these dimensions for flush contact between the sink rim and countertop underside. The 1/8-inch reveal variant reduces cutout size to 29.75x17.25 inches, creating a subtle stone reveal that's become standard in contemporary undermount installations. The 1/2-inch overhang variant cuts 29.0x16.5 inches for more pronounced reveal and simplified clip installation without tight tolerance requirements. The drop-in variant cuts the full 32x19.5-inch perimeter for top-mount applications, though this mounting style is rarely specified for Performa Cascade models. All variants feature 0.75-inch corner radii matching the SILGRANIT bowl profile for precise fit without binding. Program tool paths with 0.010-inch tolerance on critical dimensions. For granite cutting, use diamond-tooled waterjet or CNC with continuous water flow to prevent thermal stress and edge chipping. Quartz installations benefit from waterjet cutting to minimize vibration and prevent resin damage. Polish all cutout edges to 400-grit minimum for professional undermount appearance. The generous interior dimensions provide ample adjustment room for clip placement during installation.
Material Compatibility
The Performa Cascade 440067's Metallic Gray finish offers exceptional design flexibility with countertop material selection. The neutral gray tone coordinates beautifully with both warm and cool color palettes, from white Carrara-look quartz to dark absolute black granite. At 40 pounds installed weight, the sink requires robust countertop support. Three-centimeter quartz provides ideal rigidity and strength for undermount installation, with material thickness proportional to the 1.5-inch rim depth. Two-centimeter quartz can accommodate this sink with additional support rails around the cutout perimeter, though 3cm thickness is recommended for optimal long-term performance. Granite installations work well in both 2cm and 3cm thicknesses, though verify adequate material surrounds the 30x17.5-inch cutout opening - maintain minimum 4 inches to slab edge or backsplash. The Metallic Gray finish particularly complements popular gray-veined quartz patterns and provides sophisticated contrast with warm-toned granites. SILGRANIT's heat resistance to 536°F pairs well with natural stone's thermal properties. Solid surface installations require minimum 3cm thickness to support the undermount weight and prevent flex in the cascade ledge area. Avoid installations in tile or thin materials unable to provide structural support.
