The Cyclone Combo Finger Bit is a high-performance diamond CNC tool designed for fast and efficient material removal during stone fabrication. It is engineered for use on CNC machines and is ideal for cutting and shaping engineered stone and granite in professional countertop fabrication applications. The bit features an advanced combo segment design with a larger bottom segment, allowing faster incremental cutting and improved drilling capability. This design enables the tool to remove up to 3/8″ of material per pass, significantly reducing machining time and improving productivity in stone processing operations. Built with high-quality diamond segments, the Cyclone Combo Finger Bit provides smooth cutting performance, durability, and reduced chipping while milling sink cutouts, enlarging holes, or shaping stone slabs. It is optimized for wet cutting applications, which help maintain cooler operating temperatures and extend tool life during CNC machining. Key Features Combination diamond segment design for fast incremental cutting Large bottom segment allows up to 3/8″ stock removal per pass Up to 60% shorter cutting time compared to standard bits Designed for CNC machines and 5-axis saws Premium diamond segments for smooth, accurate milling Wet use only for improved cooling and durability Typical Applications Sink cut-outs and hole enlargement Slotting and contouring in stone slabs CNC stone fabrication and countertop production Available Variants FBCC158 – 1-5/8″ × 22 mm, twin segments with bottom FBCR158 – Reverse thread version, same size and configuration Technical Specs Fitting: 1/2″ gas thread Maximum RPM: 4,500 – 5,200 Feed rate: 12″ – 17″ per minute
