Description
The demi bullnose edge profile delivers a sophisticated curved finish for 2cm quartzite countertops, designed to showcase the natural beauty of this premium stone material. Quartzite's exceptional hardness—rating 7 on the Mohs scale—demands specialized fabrication parameters that differ significantly from softer stones or engineered materials. This profile features a gentle radius curve that highlights quartzite's crystalline structure and unique veining patterns while providing a durable, chip-resistant edge. This template incorporates elevated RPM settings specifically calibrated for quartzite's extreme density. Starting at 3307 RPM for roughing operations and progressing through higher speeds than granite or marble variants, these parameters ensure efficient material removal and superior polishing results on stones like Taj Mahal, Sea Pearl, and Fantasy Brown. The demi bullnose profile is particularly effective for quartzite installations where the stone's natural character should remain the focal point, providing subtle sophistication without overpowering the material's inherent visual drama.

Installation Overview
Fabricating quartzite edges requires meticulous attention to tooling quality and machine rigidity due to the material's extreme hardness. Begin with secure slab fixturing using sufficient vacuum or mechanical clamps to prevent any movement. The profile sequence initiates with a 20mm roughing finger bit at 3307 RPM—notably higher than softer materials to maintain cutting efficiency. The nine-position polishing progression starts with 50-grit metal bond diamonds at 2646 RPM, advancing through 100, 200, 400, 800, 1500, 3000, and 6000 grit stages with progressively increasing speeds up to 3969 RPM. Each stage should be executed with consistent feed rates and generous water flow to manage heat and silica dust. Final buffing at 3780 RPM produces the characteristic high-gloss finish that makes quartzite so desirable.
CNC Cutting Notes
Quartzite fabrication places significant demands on CNC equipment and tooling. Use only premium-grade diamond tooling rated for hard natural stone, as quartzite will quickly wear inferior products. Maintain spindle speeds as specified—the higher RPMs are necessary for efficient cutting and prevent tool loading that can cause chatter or surface imperfections. Feed rates should be conservative, typically 50-70 inches per minute, allowing adequate time for diamonds to engage the dense crystalline structure. Monitor tool wear closely and replace pads before they become glazed or ineffective. Ensure your machine's coolant system delivers adequate water flow to all contact points, as quartzite generates substantial heat during processing.
Material Compatibility
This template is engineered exclusively for 2cm natural quartzite slabs with a thickness of approximately 0.787 inches. Quartzite's metamorphic composition of fused quartz crystals creates a material significantly harder than granite, requiring the elevated RPM parameters and aggressive diamond tooling specified in this profile. The template is not suitable for engineered quartz (which despite similar naming is compositionally different) or softer natural stones. For quartzite slabs of different thicknesses or laminated constructions, refer to the corresponding material-specific templates that account for dimensional variations.
