Details: High measurement accuracy ensures quick and easy centering/zeroing of mechanical spindle and workpiece data. Accuracy and reproducibility of drilling, milling, turning and grinding equipment, etc., precise positioning. Absolute zero discoverer. The purpose of the edge finder is to use a coordinate system to determine the position of the workpiece on the machine. Suitable for all modern CNC lathes and milling machines or machining centers, as well as conventional machine tools. The ideal application is 400-600 rpm. Especially the 4mm probe is ideal for zeroing small holes or grooves, The lower end of rotation is magnetically shielded. The measurement accuracy can reach 0.005mm. High strength and hardness are also suitable for long-term use. Feature: Dimensions: about 90x18mm, probe diameter is about 4mm: Button: about 10mm in diameter Package includes: 1 * Edge Finder
