Product Introduction:
ER collet chucks with BT30 and BT40 tapers are a class of high-precision toolholders widely used in CNC machining centers. They serve as the critical "bridge," connecting the machine tool spindle to various cutting tools like end mills, drills, and reamers. The "high-precision" designation refers to models that offer superior concentricity, enhanced rigidity, and are optimized for high-speed operations.
