OMA CNC Finger Bit – Yellow (Medium Granite)

The OMA CNC Finger Bit – Yellow (Medium Granite) is a precision diamond finger bit designed specifically for use on medium-hard natural stone materials such as granite in CNC machining applications. Built with a robust 8-segment diamond layout, this finger bit delivers smooth material removal, consistent cutting performance, and long tool life when profiling and machining sink cutouts, internal contours, and complex shapes in stone slabs.
Featuring a compact diameter and optimized segment geometry, the Yellow OMA bit excels when running at typical CNC feed rates (e.g., 14–25 in/min) and spindle speeds suitable for granite and similar stones. Fabricators report even wear patterns and reliable performance, making it a trusted choice for both production shops and custom fabrication environments.
This finger bit is part of the broader OMA Systems CNC tooling family, which includes dedicated bits for multiple materials and cutting profiles. The yellow color specifically indicates a medium-hard granite application, giving a balance of speed and durability when cutting stone on CNC routers or bridge saw CNC heads.
