Techniks 04216-10 ER16 Collet 10mm Through Coolant

Product Description

The TECHNIKS 04216-10 is an ER16 series collet designed for precision workholding in CNC machining and milling applications. This collet accepts a 10mm clamping diameter and features through-coolant capability, allowing coolant to be delivered directly to the cutting zone for improved chip evacuation and tool life. With a total indicator runout (TIR) of 0.005mm, it delivers the concentricity required for finish milling, drilling, and reaming operations. Machinists and CNC setup technicians install this collet into compatible ER16 collet chucks as part of standard tooling configurations on machining centers and lathes.

This collet is suited for use in production and job-shop environments where repeatable, accurate tool holding is required. The ER16 series is one of the most common collet standards in the industry, making this collet a direct-fit replacement or addition to existing ER16 tooling setups. Through-coolant support makes it well suited for deep-hole drilling and high-speed operations where heat management is critical.

Key Features

• ER16 collet series for use with standard ER16 collet chucks
• 10mm clamping diameter for metric tooling
• Through-coolant design directs fluid to the cutting zone
• TIR of 0.005mm for high concentricity and precision
• Compact and lightweight at 0.075 pounds

Compatibility

Designed as an OEM-style replacement or standard addition for use with ER16 collet chucks in CNC machining center and lathe tooling systems.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the spindle and collet chuck are clean and free of debris before seating the collet. Torque the collet nut using a proper ER collet wrench to achieve consistent clamping force and runout performance. Do not use impact tools when tightening the collet nut.
