The Cyclone Finger Bits are specifically designed for use with CNC machines and are perfect for cutting and shaping engineered stone, granite, and marble. These bits are for wet use only and are available in two sizes—1 5/8” and 2 1/2”—to suit different granite thicknesses. The bottom segment allows the CNC operator to drill into the slab, similar to a core bit. The innovative 6-segment finger bit features a unique reverse apple core design, with a thicker middle section for improved performance. Recommended parameters for the FB158 include a feed rate of 8″ to 12″ per minute and an operational speed of 4500 to 5500 RPM, ensuring optimal precision and efficiency.
