Techniks 04211-01.5 ER11 Collet 1.5 Mm

Product Description

The TECHNIKS 04211-01.5 is an ER11 series collet designed for precision workholding in CNC machining applications. With a collet size of 1.5 mm and a total indicated runout (TIR) of 0.005 mm, this collet delivers the accuracy required for small-diameter tooling in high-precision setups. Through-coolant capability allows cutting fluid to be delivered directly to the tool tip, supporting extended tool life and improved chip evacuation. Machinists and CNC operators install this collet into compatible ER11 collet chucks as part of standard tooling configurations on milling machines, machining centers, and routers.

This collet is suited for light-duty precision machining where small tool diameters and tight tolerances are required. Typical applications include engraving, drilling, and milling with miniature end mills or drills. The ER11 series is widely used in production and job-shop environments where compact toolholding systems are needed. The through-coolant feature makes it especially useful in setups where direct coolant delivery to the cutting zone is part of the process plan.

Key Features

• ER11 collet series for use with standard ER11 collet chucks
• 1.5 mm collet size for small-diameter tooling
• TIR of 0.005 mm for high-precision runout control
• Through-coolant compatible for direct fluid delivery to the cutting edge
• Lightweight at 0.2 pounds for easy handling and quick changeovers

Compatibility

Designed as an OEM-style replacement and standard fitment collet for ER11 collet chuck systems used in CNC milling, drilling, and routing applications.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before installing or removing the collet, ensure the machine spindle is fully stopped and the control is in a safe state. The collet should be seated properly into the collet nut before threading onto the chuck body. Use a calibrated torque wrench and the appropriate ER11 collet nut spanner to achieve proper clamping force without over-tightening.
