Description
The Round Data Port 4-inch template is the industry-standard solution for cable management and connectivity in modern countertop fabrication. This circular cutout template accommodates standard 4-inch grommets, data ports, and power modules used in conference tables, office desks, kitchen islands, and commercial workspaces. The precision DXF file enables stone fabricators to create perfectly circular 4-inch diameter openings in granite, quartz, marble, and solid surface materials using CNC routers or manual tools. Round data ports provide a clean, professional appearance while offering cable pass-through capabilities for power cords, USB cables, HDMI connections, and network wiring. The 4-inch diameter is the most common size in commercial and residential applications, providing adequate space for bundled cables while maintaining countertop structural integrity. Ideal for tech-forward kitchen islands with charging stations, modern office furniture, co-working tables, and any application requiring organized cable management in premium stone surfaces.

Installation Overview
Installing a 4-inch round data port requires precision drilling or CNC routing to achieve a perfectly circular cutout without chipping or cracking the countertop material. Begin by marking the exact center point of your desired grommet location using the DXF template as a reference, ensuring the cutout is positioned at least 6 inches from countertop edges and avoiding any sink or cooktop proximity. For CNC installations, program a circular toolpath with a diameter of exactly 4.0 inches using a 1/4-inch or smaller diameter diamond router bit for stone materials. Carbide bits work well for solid surface materials like Corian. Set spindle speeds to 15,000-18,000 RPM for granite and quartz with feed rates around 80-100 inches per minute. Apply continuous water cooling throughout the cutting process to prevent heat buildup and minimize dust. For manual installations, use a 4-inch diameter diamond hole saw attached to a variable-speed drill, starting at slow speeds to establish the cut before increasing to operational speed. Apply masking tape over the cut area to reduce surface chipping and use a spray bottle to keep the cutting area wet. The standard 4-inch cutout provides 3.74 inches of usable interior diameter after grommet installation, sufficient for most cable bundles. Verify clearance below the countertop surface as some data port models require 2-6 inches of depth for housing and cable routing.
CNC Cutting Notes
CNC cutting 4-inch round data port openings is straightforward with proper tooling and programming. Use a 1/4-inch or 3/16-inch diameter diamond-coated router bit for optimal results in granite and quartz materials. Program a circular interpolation toolpath at exactly 4.0 inches diameter, with the bit following the circle's edge rather than plunging straight through. Set your CNC controller to climb milling mode for cleaner edges with less chipping. For 2cm material, a single depth pass may suffice, but 3cm materials benefit from two passes at 50% depth each to reduce tool stress and improve edge quality. Spindle speeds should range from 15,000-18,000 RPM with feed rates between 60-100 inches per minute, depending on material hardness. Always enable flood cooling or misting systems to manage heat and clear debris. If your CNC table uses vacuum hold-down, place support material under the cutout area to prevent the circular core from becoming a projectile when it separates from the parent material. Alternatively, program small tabs (0.020-0.030 inch thick) at 3-4 points around the circumference to retain the center piece until cutting completes. For manual finishing, lightly sand the interior edge with 220-grit diamond hand pads to remove any micro-chips. The round shape naturally distributes stress evenly, making it less prone to cracking than rectangular cutouts during installation.
Material Compatibility
Round 4-inch data port cutouts are universally compatible with all common countertop materials, making them one of the most versatile specialty fixtures for fabricators. Granite in both 2cm and 3cm thicknesses accepts 4-inch grommets perfectly, with the circular shape providing excellent structural integrity. Popular granite colors like Black Galaxy, Uba Tuba, and Kashmir White machine cleanly with diamond tooling. Engineered quartz materials including Caesarstone, Silestone, Cambria, and Viatera are ideal for data port installations, offering consistent density and minimal void spaces that could compromise the cutout edge. The non-porous nature of quartz also protects electronic components from moisture. Quartzite requires diamond tooling but produces beautiful results with its natural patterns framing the circular opening. Solid surface materials like Corian, Staron, LG HI-MACS, and Wilsonart cut easily with carbide tools and allow for color-matched grommet flanges that create seamless installations. Porcelain slabs work well for 4-inch round cutouts when using specialized diamond core bits at very slow speeds. Marble is compatible but requires careful placement away from natural veins or fissures that could propagate cracks from the cutout edge. Soapstone machines easily but its softer nature means grommet flanges should have adequate surface contact area to prevent impressions over time. For thin materials like 1.2cm porcelain or laminate, reinforce the underside with plywood backing around the cutout perimeter.
