Answer summary
What is the Alpha International U301-25 Stainless Steel Single Bowl Undermount Cutout DXF template for?
Alpha International U301-25 Stainless Steel Single Bowl Undermount 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 Alpha International U301-25 Stainless Steel Single Bowl Undermount 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
Alpha International U301-25 Stainless Steel Single Bowl Undermount 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 Alpha International U301-25 is a premium 18-gauge stainless steel undermount sink engineered for professional countertop fabrication. Measuring 30 inches wide by 18 inches deep, this single bowl design features elegant rounded corners with a 1.063-inch radius that complements both traditional and contemporary kitchen aesthetics. Our comprehensive DXF template package includes four cutout variants optimized for different installation methods and material thicknesses. Stone fabricators value the U301-25 for its generous bowl capacity, durable T-304 stainless construction, and compatibility with standard 33-inch cabinet bases.
Installation Overview
Proper installation of the U301-25 ensures long-term performance and customer satisfaction. The sink requires a minimum 33-inch cabinet width to provide adequate support and plumbing clearance. For standard undermount installations in 3cm material, use the 1/8-inch reveal variant which creates a 27.75 x 15.75 inch cutout - this configuration balances edge protection with maximum bowl exposure. The rounded corner design distributes stress more evenly than sharp corners, reducing crack risk in natural stone materials. Apply a continuous bead of high-quality silicone adhesive around the entire cutout perimeter, positioning the sink carefully before the adhesive sets. Install mounting clips at 6-8 inch intervals, ensuring even pressure distribution. The center drain location at 3.5 inches diameter accommodates standard disposal units and provides optimal drainage performance.
CNC Cutting Notes
CNC programming for the U301-25 requires attention to the 1.063-inch corner radius specification. Use a 1/4-inch ball nose bit or larger to achieve smooth radius transitions without tool chatter. For optimal results, run a roughing pass at 100 IPM leaving 0.020 inches material, followed by a finishing pass at 60 IPM. The rounded corners eliminate the need for square corner cleanup, reducing programming time and improving edge quality. When cutting the 1/8-inch reveal variant, remember that the 27.75 x 15.75 inch cutout maintains the same corner radius as the no-reveal option. Set spindle speed to 18,000-22,000 RPM for carbide tooling in granite or engineered stone. Always verify G-code corner coordinates match the specified radius.
Material Compatibility
The U301-25 template excels across diverse countertop materials, with the rounded corner design providing particular advantages in natural stone applications. Granite fabricators appreciate how the 1.063-inch radius reduces stress concentration points that can lead to corner fractures, especially in materials with prominent veining or fissures. For quartz installations (Cambria, Caesarstone, Silestone, Viatera), the template's precision ensures consistent results whether using 2cm or 3cm slabs. The 28-inch bowl width maximizes usable sink space while maintaining adequate edge support in standard 25-inch depth countertops. Quartzite and marble installations benefit from the 1/2-inch overhang variant, which provides additional material support around the cutout perimeter. Solid surface materials integrate seamlessly with proper adhesive selection.
