Techniks 04225-11 ER25 Collet 11mm Through Coolant

Product Description

The TECHNIKS 04225-11 is an ER25 series collet designed for precision toolholding in CNC machining and milling applications. It accepts a collet size of 11 millimeters and delivers a Total Indicator Runout (TIR) of 0.0002 inches (0.0050 mm), making it suitable for operations that demand tight concentricity tolerances. The collet features through-coolant capability, allowing cutting fluid to pass directly to the cutting zone for improved chip evacuation and tool life. Machinists, toolroom technicians, and CNC setup personnel are the primary installers of this component.

This ER25 collet fits standard ER25 collet chucks used across a wide range of machining centers, mills, and lathes in both production and job-shop environments. The ER25 series is one of the most widely adopted collet standards in the industry, making this collet compatible with a broad installed base of toolholding equipment. Its through-coolant design is particularly well suited to deep-pocket milling, drilling, and high-speed finishing passes where heat and chip buildup are concerns.

Key Features

• ER25 collet series for broad chuck compatibility
• 11mm collet size accommodates matching shank tooling
• TIR of 0.0002 inches (0.0050 mm) for precision concentricity
• Through-coolant capable for improved tool life and chip evacuation
• Compact form factor suited to production and toolroom use

Compatibility

Designed as a standard ER25 series collet for use with ER25-compatible collet chucks and toolholding systems.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician with the machine in a full stop and lockout state. Use a properly sized collet nut and torque wrench rated for ER25 assemblies; do not over-tighten by hand without a wrench, as this can damage the collet taper. Inspect the collet bore and chuck taper for chips or debris before seating. Verify runout with a dial indicator after assembly before beginning any cutting operation.
