Floating and telescoping design This Collet Chuck Holder features a floating and telescoping mechanism that protects a front float of 5 mm and a rear float of 6 mm. The design enables smooth operation and minimizes tap breakage during high-precision CNC tapping tasks. High concentricity and durability Quenched and tempered for outstanding concentricity and surface quality. The robust construction provides long-term performance even under demanding machining conditions. Premium material and heat treatment The body is made from fully carburized 20CrMRTI steel and heat-treated for increased strength. Inner and outer diameters are precision-ground to enhance wear resistance and ensure long service life. Versatile clamping solution Delivers superior clamping quality compared with ordinary chucks; compatible with all common machine chucks. Its versatility makes it ideal for various CNC turning applications, delivering consistent results every time. Use scenarios - CNC turning operations requiring high concentricity and reduced tap breakage during tapping tasks. - Small-diameter workpieces and precision threading in automated or manual turning setups. - Multi-tasking turning centers and job shops needing a flexible, reliable holding solution.
