Cyclone Finger Bits are professional-grade diamond CNC tools designed for fast drilling, milling, and material removal in stone fabrication. These finger bits are engineered to deliver smooth and precise cutting when working with engineered stone, granite, and marble, making them ideal for countertop fabrication and other CNC machining applications. The tool features a 6-segment diamond design with a bottom segment, allowing operators to drill directly into the slab, similar to a core bit. This design improves cutting efficiency and enables smooth hole enlargement, slotting, and shaping during CNC machining. Cyclone Finger Bits also incorporate an innovative reverse apple-core segment design, where the middle section is slightly thicker. This unique structure enhances stability, improves cutting balance, and helps extend the tool’s lifespan during heavy-duty stone processing. Designed for wet use only, the finger bits maintain cooler cutting temperatures and reduce segment wear, ensuring consistent performance and longer service life. They are widely used on CNC stone fabrication machines for precise shaping and drilling operations.
