Product Description

Venom CNC Diamond Incremental Finger Bits with Reverse M12 threading are engineered specifically for reverse-rotation CNC saws and 5-axis machining centers where standard threaded tools cannot be used. Designed for quartzite, granite, and quartz, these bits deliver smooth incremental milling, clean tracking, and long-lasting performance on dense materials.

Reverse-thread tooling is required on CNC machines where spindle rotation would loosen standard threaded tools. Venom Reverse M12 Incremental Finger Bits remain tight, stable, and secure during high-duty cutting operations including sink cut-outs, radius milling, pocketing, and incremental profiling.

Built using premium diamond segments and reinforced steel construction, these tools provide vibration-controlled performance and consistent cutting results in professional CNC production environments.
