Description
The full bullnose edge transforms a laminated granite countertop into a statement piece with its complete semicircular profile wrapping around the front edge. This premium template for 2cm+2cm laminated construction creates a 1.575-inch profile height with the rounded geometry that requires significantly more toolpath complexity than a standard eased edge. Classified as a premium tier profile with a $12 per linear foot upcharge, the full bullnose demands precise CNC programming to achieve the smooth, continuous curve from the top surface around to the bottom face. Granite's forgiving crystalline structure makes it one of the best materials for this profile, as the interlocking mineral grains polish evenly across the curved surface without the directional streaking that can occur on engineered materials.

Installation Overview
Full bullnose fabrication on laminated granite begins with verifying the epoxy bond between the two 2cm slabs at the seam position of 0.787 inches. The semicircular profile will machine directly through this joint, making bond integrity critical to the finished result. Any voids or weak spots in the lamination will be exposed and amplified by the curved toolpath. Load the DXF template and note that the bullnose geometry requires a multi-pass roughing strategy rather than the single-pass approach used on flat profiles. The 25mm roughing finger bit at 3500 RPM removes material in progressive depth passes to establish the semicircular shape, typically requiring three to four roughing cycles. Feed rate of 50-65 IPM works well for granite during this shaping phase. After roughing, the seam polishing pass at 2500 RPM blends the lamination joint along the curve. The main polishing sequence runs through all nine positions from 50 grit at 2800 RPM to the buff pad at 4000 RPM, with the curved profile requiring approximately twice the polishing time per linear foot compared to a flat eased edge. Each polishing pad must follow the full radius of the semicircle with consistent contact pressure throughout the arc. Uneven pressure creates flat spots that are immediately visible on the finished bullnose.
CNC Cutting Notes
Full bullnose requires multi-pass roughing to establish the semicircular geometry. Set the 25mm roughing finger bit at 3500 RPM with 50-65 IPM feed rate, using three to four progressive depth passes. The seam pass at 2500 RPM blends the lamination joint along the curved surface. Polishing runs through nine positions from 50 grit at 2800 RPM to buff at 4000 RPM. The curved toolpath must maintain consistent contact pressure across the entire semicircular arc. Use 0.3-0.5mm stepover for complete coverage of the radius. Water flow of 2.5 GPM ensures adequate cooling over the larger polished surface area. Total cycle time is approximately double that of a flat eased edge.
Material Compatibility
Granite is the premier natural stone for full bullnose fabrication because its interlocking crystalline structure polishes uniformly across curved surfaces. This template works with all granite varieties, though stones with large crystal structures like Giallo Ornamental may show more visible grain transitions across the bullnose radius than fine-grained varieties like Absolute Black. The laminated 2cm+2cm construction is common for full bullnose because the thicker combined profile creates a more dramatic radius. Softer stones like marble can also achieve a full bullnose but require the marble-specific parameter adjustments. Engineered quartz full bullnose fabrication carries elevated heat risk due to the larger polished surface area.
Where to Buy
Full bullnose profiling wheels and bullnose-specific polishing pads are available from GranQuartz, Braxton-Bragg, Diamut, and Weha. Dedicated bullnose router bits produce the initial radius more efficiently than standard finger bits on high-volume production.
