Collet Chuck Tool Holder for CNC Milling, NT40-ER32

【One-Piece 20CrMnTi Steel】The one-piece 20CrMnTi steel construction evenly distributes cutting pressure across the needle cage, ensuring stable performance during high-feed machining operations and under high chip loads.
【Case Hardened and Quenched】Surface case hardening provides high wear resistance and fatigue endurance, while retaining a mild steel core that absorbs shock during interrupted cuts.
【Precision Ground Tailstock】The fully ground tailstock ensures consistent contact with the spindle taper bore, reducing runout and protecting spindle alignment for repeatable tool changes.
【High-Precision Polished Finish】The tailstock and internal bore are finished with fine grinding technology, providing high centering accuracy and a smooth surface that reduces vibration. 30,000 rpm.
【CNC and Lathe Compatibility】The NT40-ER32 interface fits standard CNC milling machines, drills and lathes, supporting ER32 collets for secure clamping of cutting tools in industrial environments.
