The Alpha International U271 K Series represents a professional-grade single bowl undermount sink solution designed for modern stone fabrication shops. This 27-inch stainless steel sink features sharp corners and a generous 9-inch bowl depth, making it ideal for contemporary kitchen installations. Our production-ready DXF template includes four cutout variants to accommodate different installation preferences, from flush-mount to drop-in configurations. Fabricators appreciate the precision-engineered design that ensures consistent results across granite, quartz, and solid surface materials.
Installation Overview
Installing the U271 K Series requires careful attention to cutout precision and proper support systems. The sink measures 27 inches overall width by 18 inches depth, with a bowl opening of 25x16 inches. For undermount installations, we recommend the 1/8-inch reveal variant, which provides optimal edge support while maintaining clean sightlines. The no-reveal option works best for thicker materials (3cm+) where maximum bowl size is desired. When working with engineered stone, apply a continuous bead of silicone around the cutout perimeter and use the manufacturer-supplied mounting clips at 6-8 inch intervals. The 30-inch minimum cabinet requirement ensures adequate structural support and allows proper plumbing clearance. Always verify sink positioning before cutting, as the offset drain configuration may impact cabinet layout decisions.
CNC Cutting Notes
The U271 K Series DXF template is optimized for CNC router operation with precise corner geometry. Sharp corners require careful tool selection - we recommend a 1/4-inch diameter spiral upcut bit for roughing and a 1/8-inch bit for corner finishing. Set your cutting depth to material thickness plus 0.030 inches to ensure complete breakthrough without tool damage. Feed rates of 80-120 IPM work well with most stone materials. For the 1/8-inch and 1/2-inch reveal variants, the reduced cutout dimensions provide excellent edge support but require attention to corner radius consistency. Always run a simulation before cutting expensive material.
Material Compatibility
This template delivers excellent results across all common countertop materials. For granite installations, the sharp corner design complements contemporary aesthetics while the 27-inch width fits standard cabinet bases. Quartz fabricators will appreciate the template's compatibility with Cambria, Caesarstone, and Silestone materials - the 9-inch bowl depth provides ample workspace without compromising slab integrity. When working with quartzite or marble, consider the 1/2-inch overhang variant to maximize edge protection around the cutout. Solid surface materials like Corian also work well, though undermount installations require proper adhesive selection and adequate support blocking.
