Descripción
This incremental finger tip bit is designed for quartzite, granite, and quartz on radial arm and CNC machines. Its 20 x 20 x M12 configuration and tapered outer diameter support incremental stock removal while reducing side friction and helping minimize chipping.
Controlled stock removal for stone fabrication
For fabricators working quartzite, granite, or quartz, the tapered outside profile helps reduce contact along the sides of the bit. Remove material in incremental passes using the operating parameters below to keep the machining process controlled.
Features and compatibility
- Suitable materials: quartzite, granite, and quartz.
- Machine applications: radial arm and CNC machines.
- Size and connection designation: 20 x 20 x M12.
- Tapered outer diameter helps reduce side friction.
- Designed to help reduce chipping during incremental machining.
Operating parameters
- Spindle speed: 4,500–5,000 RPM.
- Stock removal: 1–1.5 mm per pass.
- Feed rate: 15–20 inches per minute.
Confirm the M12 connection and bit dimensions are compatible with your machine setup before ordering.
