Working Parameters

Product Details

Drilling clean, chip-free holes in dense stone surfaces requires a tool engineered to withstand extreme friction and structural stress. This Universal Segmented Core Drill is a professional-grade fabrication tool specifically formulated to cut through the industry’s most challenging materials, including extra hard granites, engineered quartzite, and ultra-compact sintered surfaces.

Standard continuous-rim drills often glaze over or overheat when encountering highly abrasive quartz networks. This design utilizes advanced segments featuring a high-concentration diamond matrix that continuously exposes sharp cutting edges. This ensures rapid material penetration while maintaining straight, precise holes for plumbing lines, faucet anchors, and structural hardware installations without risking catastrophic slab cracking.

Technical Features

Universal Hard Material Matrix: Specially formulated bond engineered to cut through extra hard granites, quartzite, and porcelain without glazing or slowing down.
Turbo-Segmented Geometry: The advanced segmented design maximizes cooling fluid flow and slurry ejection, preventing heat buildup and ensuring rapid drilling speeds.
Core Alignment Protection: Built with a reinforced, balanced steel body to eliminate runout and vibration, protecting fragile stone edges from chipping.
Four Precision Diameters: Available in a versatile range of core diameters—20mm, 25mm, 30mm, and 35mm—perfectly sized for standard anchor bolts, soap dispensers, and kitchen faucet holes.
Optimized Water Feed Delivery: Engineered with internal water-feed compatibility to ensure maximum lubrication directly at the cutting zone for extended tool life.

Tool Application Style

CNC & Manual Fabrication Machinery: Perfectly suited for high-speed CNC machining centers, radial arm drills, and heavy-duty manual fabrication setups.
High-Density Stone Processing: The go-to drilling solution for stone fabrication shops specializing in high-end quartzite kitchen islands and heavy commercial granite countertops.
