The Omega Products ER20 Jet Coolant Sealed Collet is a precision toolholding solution designed for CNC milling, drilling, and other high-speed machining tasks. This 13mm, 10-micron accuracy collet is sized for ER20 chucks and provides a secure, repeatable grip while integrating a jet coolant sealing mechanism that delivers coolant directly to the cutting zone.

• Jet coolant sealing: Delivers coolant right to the cutting zone to improve chip evacuation, reduce heat buildup, and extend tool life during demanding, coolant-assisted operations.
• 10 µm precision grip: Maintains tight runout and repeatable tool positioning, helping you achieve consistent finishes and accurate hole sizes even at high speeds.
• ER20-compatible, secure grip: Designed to fit standard ER20 collet chucks for quick tool changes and reliable clamping across a variety of tooling applications.

The combination of direct coolant delivery and a high-precision, secure grip helps streamline workflows, reduce downtime, and deliver repeatable results across production runs and precision projects. With its rugged construction and coolant-ready design, this collet supports longer tool life, stable performance, and confidence on the shop floor when exactness matters.
