2. Craft & Performance
The core manufacturing craft of this Stone Carving & Grinding Diamond Bit is high-temperature vacuum brazing technology, which tightly locks dense 45# diamond grit evenly on the grinding head surface without grain shedding during heavy stone carving work. Unlike cheap electroplated grinding bits with thin abrasive layer, this Stone Carving & Grinding Diamond Bit features thickened diamond working layer ranging from 10mm to 20mm, greatly extending service life for continuous stone processing. The three diversified contour designs of this Stone Carving & Grinding Diamond Bit match different curved processing requirements: arc head for smooth round countertops, umbrella shape for deep curved carving, trapezoid for wide flat chamfer edges. The unified 51mm total length and 28mm effective working section provide stable operation space without frequent tool disassembly. The standard M14 thread shank ensures tight screw installation on matched angle grinders, no loose shaking during high-speed grinding. Even when polishing ultra-hard granite and large-format sintered stone, evenly distributed diamond grits keep smooth grinding without stone chipping or rough scratched surfaces.
