Answer summary
What is the Alpha International U161-25 Stainless Steel Single Bowl Undermount Cutout DXF template for?
Alpha International U161-25 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 U161-25 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 U161-25 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 U161-25 is a compact 16-inch undermount sink ideal for smaller prep areas, island installations, and bar applications. This professional-grade DXF template provides four cutout variants to accommodate different reveal preferences and installation methods. Built from 18-gauge commercial-grade 304 stainless steel with a premium satin finish, the U161-25 delivers durability and easy maintenance. Our production-ready templates ensure precision CNC cutting for granite, quartz, marble, and solid surface countertops, eliminating measurement errors and reducing installation time.
Installation Overview
Installing the Alpha U161-25 requires a minimum 19-inch cabinet width and careful attention to reveal specifications. The template includes four variants: no reveal (14x15.75-inch cutout for flush mounting), 1/8-inch reveal (13.75x15.5-inch cutout for minimal overhang), 1/2-inch overhang (13x14.75-inch cutout for maximum support), and drop-in configuration (16x17.75-inch cutout matching exterior dimensions). For stone fabrication, we recommend the 1/8-inch reveal for most granite and quartz installations, as it provides optimal structural support while maintaining clean aesthetics. The sink includes undercoated insulation with rubber padding to reduce operational noise, making it suitable for open-concept kitchens. Stainless steel installation clips are provided, though professional fabricators often prefer epoxy-based undermount systems for superior long-term adhesion. The 3.5-inch drain opening accommodates standard basket strainers and disposal connections. Corner radius is R20 (approximately 0.79 inches), providing easy cleaning access while maintaining strength.
CNC Cutting Notes
This template has been optimized for CNC cutting with verified dimensions extracted directly from manufacturer DXF files. The file contains clean geometry on Layer 0 with minimal entity count (34 entities), ensuring fast processing and accurate toolpath generation. Units are confirmed as inches. When programming your CNC, use a 1/2-inch or smaller diameter bit for tight corner reproduction, though the R20 radius provides adequate clearance for standard tooling. The compact size makes this an excellent choice for nested cutting layouts, maximizing material yield from slab remnants. Tool offset compensation should account for your specific bit diameter. For polished edges, program a secondary finishing pass at reduced feed rates. The single-bowl design requires no internal bridge cuts, simplifying the cutting sequence.
Material Compatibility
The Alpha U161-25 undermount template is compatible with all common countertop materials, though installation techniques vary by substrate. For granite and quartzite (3cm thickness), the undermount style provides maximum durability and the cleanest aesthetic. Quartz and solid surface materials should use the 1/8-inch reveal to ensure adequate support, as these engineered materials can be more brittle around unsupported edges. Marble installations benefit from the 1/2-inch overhang variant to protect delicate edges from chipping. The compact dimensions make this sink particularly well-suited for remnant pieces and smaller slabs, reducing material waste. Laminate countertops should use the drop-in variant only. The stainless steel construction pairs beautifully with all stone colors, from dark absolutes to light carrara-style patterns. 18-gauge steel provides sufficient strength without excessive weight that could stress smaller cutouts.
Where to Buy
Alpha International sinks are available through kitchen and bath distributors, plumbing supply wholesalers, and online retailers. The U161-25 typically retails around $130, representing excellent value for commercial-grade stainless construction. Fabricators should verify current availability and pricing with local distributors. The sink ships with installation clips and a paper cutout template, though our precision DXF files offer superior accuracy for professional installations. Verify model number U161-25 when ordering to ensure correct sizing.
