Our CNC tooling includes diamond engraving bits, profiling wheels, and drill bits designed for routers and CNC centers. Maximize productivity in countertop cutting, edge detailing, and 3D carving. Durable bonds ensure longevity in granite, quartz, and composite materials.
Stone CNC Tools are precision-engineered diamond-embedded cutting instruments designed specifically for computer-controlled stone fabrication machines. Unlike conventional tools, they transform digital designs into intricate stone components through automated material removal processes. These tools interface directly with CNC machining centers, executing complex tasks like contouring, engraving, and 3D sculpting that would be impossible with manual methods.
Stone CNC Tools
Core Functionality
At Xiamen Sino Poly, our CNC tools feature proprietary diamond matrix technology that maintains cutting integrity during high-speed operations. The diamond grit concentration varies strategically across the tool surface - higher density at edges for aggressive cutting, gradually decreasing toward the center for thermal stability. This prevents common failures like segment warping when processing dense granites or quartzites.
Material Compatibility
Our tools process diverse materials: from soft marbles (Mohs 3-4) requiring fine-grit diamonds to ultra-hard granites (Mohs 7+). Specialized formulations address unique challenges - porous travertines need resin-filled segments to prevent tearing, while quartz composites require nano-coated diamonds to counter silica abrasiveness. Explore our full range of compatible Stone Cutting Tools for material-specific solutions.
Key Features of Modern CNC Tools
Precision Engineering
Xiamen Sino Poly tools maintain ±0.01mm dimensional tolerance through ISO 9001-certified manufacturing. Our vacuum brazing process creates metallurgical bonds between diamonds and steel bodies that withstand lateral forces exceeding 300N without deformation. Laser-etched balancing marks enable perfect dynamic alignment, eliminating vibration at spindle speeds up to 12,000 RPM.
CNC Diamond Mounted Points-5
Thermal Management
Our proprietary CoolCore™ technology incorporates micro-channel coolant pathways within tool bodies. These channels direct cutting fluids precisely to the diamond-work interface, reducing operating temperatures by 40% compared to standard tools. This prevents diamond graphitization - the primary cause of premature wear in continuous processing.
CNC Diamond Mounted Points-4
Adaptive Diamond Matrix
We engineer diamond segments with self-sharpening properties. The metal bond gradually erodes to expose fresh diamond crystals precisely when needed. This maintains consistent cutting speed throughout the tool's lifespan, unlike competitors' tools that degrade exponentially. The matrix hardness is calibrated to stone abrasiveness - softer bonds for hard stones to expose diamonds faster, harder bonds for soft stones to prolong segment life.

Industry Applications
Architectural Fabrication
In high-rise construction, our CNC tools create precision curtain wall components with tolerances of ±0.3mm. Specialized edge profilers produce perfect tongue-and-groove joints that withstand seismic forces up to 7.5 magnitude. For large-scale projects, our diamond wire rope systems enable efficient cutting of massive stone slabs with minimal kerf loss. Discover our Stone Diamond Wire Rope solutions for architectural applications.

Monument Manufacturing
Our 3D engraving bits feature 0.5mm diamond tips that render photographic details at 600dpi resolution. Variable helix angles prevent chip-clogging during deep relief carving of military memorials. For lettering applications, V-point tools maintain consistent depth across varying grain structures, ensuring uniform appearance across memorial complexes.
Monument Manufacturing
Countertop Production
Our CNC sink cutout tools feature internal coolant ports that reduce cutting temperatures by 35% in quartz composites. Specialized bullnose wheels create perfect radius edges from 3mm to 50mm with surface finishes down to 0.2μm Ra. For complex edge profiles, our multi-axis tools reduce setup time by 60% compared to conventional methods.
Countertop Production
Artistic Sculpting
Ball-nose end mills with 0.5-3mm tip radii enable intricate 3D sculpting in marble and limestone. For detailed relief work, tapered engraving bits maintain consistent depth across curved surfaces. Our specialized tools have been used to create museum-quality reproductions of classical sculptures with dimensional accuracy of 0.1mm.
