The Omega Products ER25 Jet Coolant Sealed Collet provides machinists and manufacturers with a reliable way to hold 4mm cutting tools while delivering coolant straight to the cutting zone. Its sealed design and 10-micron accuracy make it suitable for high-performance milling, drilling, and turning tasks where consistent results and extended tool life matter.

• Direct Coolant to the Cut: The jet sealing system channels coolant precisely through the collet to the tool tip, improving chip evacuation and helping tools run cooler during extended cuts.
• 10-Micron Runout Accuracy: Holds tools to tight tolerances so parts stay within specification and reduce the need for secondary finishing or rework.
• Secure Grip in Standard ER25 Chucks: Delivers strong, repeatable clamping force that keeps tools stable under varying loads without slippage or vibration.

This collet helps shops maintain longer tool life and cleaner cuts by combining precise tool holding with effective cooling, leading to fewer interruptions and more consistent part quality across production runs.
