Description
The Dupont edge profile brings clean architectural sophistication to quartzite countertops, showcasing the natural beauty and extreme durability of this premium metamorphic stone. This template is specifically engineered for laminated 2cm+2cm quartzite construction (1-9/16 inches total thickness) with optimized parameters that address quartzite's exceptional hardness and density. Quartzite is among the hardest natural stones used in countertops, requiring higher RPM settings and specialized diamond tooling to achieve the mirror-polish finish this luxury material demands. The stepped Dupont profile creates striking visual depth that highlights quartzite's characteristic veining, crystalline structure, and color variations ranging from whites and grays to golds, greens, and dramatic exotics. This template specifies elevated RPM settings throughout the fabrication process, ranging from 2940 RPM for roughing up to 4200 RPM for final polishing and buffing, approximately 5% higher than granite to effectively polish quartzite's interlocked quartz crystals. The 9-position polishing sequence from 50 grit metal bond through 3000 grit resin bond and buff produces the deep gloss that quartzite is famous for. Fabricators value this profile for showcasing premium quartzite installations while commanding standard $18 per linear foot pricing despite the additional machining challenges.

Installation Overview
Fabricating the Dupont edge on laminated quartzite requires robust equipment and patience due to the material's extreme hardness (Mohs 7+). Verify the lamination bond has fully cured using adhesives rated for high-density materials, as quartzite's density transmits vibration more readily than softer stones. Support the slab edge with rigid backing capable of withstanding the higher cutting forces quartzite generates. Use industrial-grade 25mm roughing finger bits at the elevated 3675 RPM with conservative feed rates of 50-70 inches per minute. Quartzite's hardness means slower material removal but also excellent edge stability with minimal chipping when properly supported. Execute the seam polishing pass at 2625 RPM to blend the lamination line, applying consistent pressure as quartzite's hardness resists polishing action. Progress through the demanding 8-position polishing sequence from 50 grit through 3000 grit and buff, using the elevated RPM settings (up to 4200 RPM) specified for quartzite. Each polishing position takes longer on quartzite than softer materials as the hard crystalline structure resists abrasive action. Total fabrication time is 45-60 minutes per linear foot, significantly longer than granite but producing an unmatched polished finish on this premium material.
CNC Cutting Notes
CNC programming for quartzite demands robust equipment and premium diamond tooling to handle the material's extreme hardness. Use industrial-grade 25mm diamond finger bits specifically rated for hard materials at the elevated 3675 RPM roughing speed. Feed rates must be reduced to 50-70 IPM to prevent excessive tool wear and potential tool breakage, quartzite's hardness creates higher cutting forces than any other common countertop material. The Dupont profile's straight-line geometry helps minimize cutting time compared to curved profiles. Plan for more frequent tool changes as quartzite's abrasive nature dulls diamond tooling faster than granite. After roughing, the seam polishing pass at 2625 RPM requires high-quality flexible backing pads to conform to the lamination line. During polishing, start with 50 grit metal bond at 2940 RPM and progress through the sequence to the maximum 4200 RPM for final 3000 grit and buff positions. The elevated RPMs are essential for quartzite as lower speeds simply won't generate sufficient polishing action on the hard crystalline surface. Use abundant water during all operations to control heat, evacuate chips (which are sharp and abrasive), and extend tool life. Quartzite polishing generates significant heat even with water, so monitor temperatures and allow cooling between passes. Expect tooling costs 20-30% higher than granite due to accelerated wear on diamond abrasives.
Material Compatibility
This template is specifically optimized for natural quartzite materials in laminated 2cm+2cm construction. Quartzite is metamorphosed sandstone composed of interlocked quartz crystals, making it one of the hardest natural stones (Mohs 7-7.5, harder than granite). Works on all quartzite varieties including popular types like Taj Mahal, Sea Pearl, Macaubas White, Fantasy Brown (actually quartzite not marble), and exotic quartzites in dramatic colors. The elevated RPM settings (2940-4200 range) are calibrated for quartzite's extreme hardness and produce the deep mirror polish that makes this material so desirable. Important: this template is for natural quartzite, not engineered quartz (which despite similar names is a manufactured product requiring different parameters - see the quartz template). Laminated construction provides adequate thickness for the Dupont profile while managing material costs on this premium stone. The through-body nature of natural quartzite means edges display the same veining and color as the surface.
Where to Buy
This Dupont edge profile DXF template for quartzite is available for free download from SlabWise. Compatible with all professional CNC stone fabrication systems equipped to handle hard materials. Natural quartzite slabs in 2cm thickness are available from specialty stone importers and high-end distributors as quartzite is a premium material not stocked at all yards. Industrial-grade diamond tooling rated for hard materials is essential and available from Alpha Tools, Weha, Braxton-Bragg, and specialized suppliers. Specify extra-hard bond formulations for quartzite applications to maximize tool life and polishing efficiency.
