Product Description
The CNC Diamond Incremental Finger Bit D20×20TXL 2" with 1/2" Gas connection is a precision diamond tool engineered for professional CNC stone fabrication. Designed for smooth incremental milling and controlled material removal, this finger bit delivers clean tracking, consistent cutting performance, and long tool life on quartz, quartzite, granite, and other hard natural stone.
Built for standard-rotation CNC machines using 1/2" Gas threaded tooling, this incremental finger bit is ideal for sink cut-outs, pocket milling, radius shaping, and multi-pass incremental machining. The compact D20 diameter offers excellent maneuverability and accuracy while maintaining stable performance in high-production environments.
Manufactured with premium diamond segments and a reinforced steel body, this bit delivers vibration-controlled cutting and dependable CNC performance.
