Techniks 04216-01 ER16 Collet 1 Mm Through Coolant

Product Description

The TECHNIKS 04216-01 is an ER16 series collet designed for precision workholding in CNC machining and toolholding applications. It accepts a 1 mm clamping diameter and features through-coolant capability, allowing coolant to pass directly through the collet to the cutting tool. The collet holds a total indicator runout (TIR) of 0.005 mm, making it suitable for high-precision drilling, milling, and reaming operations. This collet is installed by machinists and CNC technicians working with ER16-compatible collet chucks on machining centers, lathes, and manual mills.

The 04216-01 is intended for use in light-duty to medium-duty machining environments where small-diameter tooling requires secure, accurate clamping. The 1 mm capacity suits micro-tooling applications such as fine drilling, engraving, and precision milling. Through-coolant support makes it appropriate for deep-hole drilling and high-speed operations where direct coolant delivery to the cutting edge reduces heat and extends tool life.

Key Features

• ER16 collet series for use with standard ER16 collet chucks
• 1 mm clamping diameter for micro and small-diameter tooling
• Through-coolant design directs coolant flow to the cutting tool
• 0.005 mm TIR for high-precision runout control
• Compact form factor suited for high-speed spindle applications

Compatibility

Designed as a standard ER16-series collet compatible with ER16 collet chucks used on CNC machining centers, milling machines, lathes, and similar toolholding equipment.

Installation Notes

ER collets are installed by machinists or CNC technicians into ER16-compatible collet chucks using the appropriate collet nut and spanner wrench. Ensure the chuck and spindle are fully stopped and the machine is powered down before inserting or removing collets. Inspect the collet bore and chuck taper for debris or damage before installation, as contamination directly affects runout and clamping force. Do not exceed the collet clamping range for the selected tool diameter.
