Product Features: The equal-diameter extension rod is suitable for extending equal-diameter basic tool holders such as LBK, DCK, and CK series. The different-diameter extension rod is suitable for deep-hole machining to enlarge the tool holder diameter, providing an anti-vibration effect when installing boring heads with smaller diameters.
