The Blanco 443060 Diamond is a versatile 25-inch dual-mount single bowl sink crafted from SILGRANIT composite material. This compact design excels in small kitchens, secondary prep areas, and island installations where space efficiency meets durability. Our precision DXF template provides four installation variants to accommodate different reveal preferences and mounting styles, ensuring perfect fitment whether you're installing undermount or drop-in. The Diamond series features Blanco's patented SILGRANIT material, engineered from 80% granite composite to deliver exceptional resistance to heat, scratches, and staining.
Installation Overview
Installing the Blanco 443060 Diamond requires careful consideration of your countertop material and desired aesthetic. For granite, quartz, and solid surface installations, the undermount variants offer clean lines and easy maintenance, with the no-reveal option providing maximum bowl capacity while the 1/8-inch and 1/2-inch reveal options create increasingly pronounced ledges for visual interest. The drop-in variant accommodates laminate countertops and retrofit applications where undermount installation isn't feasible. Minimum cabinet width is 27 inches for undermount installations and 25 inches for drop-in, though we recommend 30 inches for comfortable installation access. The sink accepts a single-hole faucet with provision for one additional knockout hole for accessories like soap dispensers or side sprayers. Template accuracy is critical since SILGRANIT material doesn't tolerate field modifications, making our CNC-ready DXF files essential for first-time-right fabrication.
CNC Cutting Notes
When programming your CNC for the 443060 Diamond template, use conservative feed rates on natural stone to prevent microchipping at corners. The template includes 0.75-inch corner radii that require smooth interpolation rather than segmented approximations. For quartz and granite, we recommend 10mm diamond router bits running at 12,000-15,000 RPM with feed rates around 100-120 inches per minute. Set your Z-axis depth to cut completely through the material plus 0.125 inches for clean breakthrough. Apply continuous water cooling to prevent heat buildup that can discolor the cut edge. The no-reveal variant cuts at the exact bowl perimeter, requiring exceptional edge finishing since any cut imperfections will be visible from above when the sink is installed.
Material Compatibility
The Blanco 443060 Diamond works beautifully with all common countertop materials, though installation methods vary by substrate. On granite and engineered quartz, undermount installation with epoxy and mechanical clips provides the most refined appearance and easiest cleanup. Solid surface materials like Corian allow for undermount or drop-in installation with adhesive bonding and optional integrated drip edges. For laminate countertops, the drop-in variant is the only viable option, requiring careful measurement to ensure the rim seats properly on the substrate without gaps. The SILGRANIT composite material weighs approximately 27 pounds, requiring adequate support structure in the cabinet base. Ensure your countertop thickness accommodates the sink depth plus the mounting system. Minimum countertop thickness is 3/4 inch for drop-in installation and 2cm (approximately 3/4 inch) for undermount, though we recommend 3cm material for undermount installations to provide better structural integrity.
