Meet the Omega Products HSK63A ER16 MINI Collet Chuck — a high-speed toolholder designed for demanding CNC milling tasks. Built on the proven HSK63A interface, it delivers precise, rigid tool clamping that minimizes runout and maximizes cutting efficiency for a wide range of tools.

With ER16 compatibility and a gauge length of 160 mm, plus a G2.5 balancing specification, this compact chuck combines reach, balance, and stability for smooth operation at speeds up to 25,000 RPM.

• Rigid HSK63A interface for precise, stable clamping: Minimizes runout and delivers repeatable accuracy at high speeds, improving cut quality and part tolerances.
• Versatile ER16 collet system: Provides a strong grip across a broad range of tool shanks, reducing tool changes and ensuring reliable performance with many milling tools.
• G2.5 balanced for high-speed machining: Ensures smooth, low-vibration operation at 25,000 RPM, extending tool life and improving surface finish.

This toolholder is designed to enhance workflow across professional shops and workshops alike. Its robust construction, precise balance, and flexible collet system help you achieve consistent results, minimize downtime, and deliver reliable performance on demanding jobs—from prototyping through production milling.
