Techniks 04216-01.5 ER16 Collet 1.5 Mm Bore

Product Description

The TECHNIKS 04216-01.5 is an ER16 series collet designed for precision workholding in CNC machining centers, milling machines, and collet chuck toolholding systems. With a 1.5 mm bore size and a total indicator runout (TIR) of 0.005 mm, this collet delivers the clamping accuracy that production and tool room environments demand. Through-coolant capability allows cutting fluid to reach the tool tip directly, supporting higher-speed operations and extended tool life. Licensed machinists and CNC setup technicians are the primary installers of this collet type.

This collet is suited for light-duty CNC milling, drilling, and reaming applications where small-diameter tooling in the 1.5 mm range is required. The ER16 series is a widely adopted standard in both job shop and production machining environments. It is appropriate for residential shop equipment as well as commercial machine tool applications wherever an ER16-compatible collet chuck is in use.

Key Features

• 1.5 mm bore size for precise small-diameter tool clamping
• ER16 collet series - broad compatibility with ER16 collet chucks
• TIR of 0.005 mm for high-accuracy concentricity
• Through-coolant design routes cutting fluid directly to the cutting edge
• Lightweight at 0.08 pounds - suitable for high-speed spindle applications

Compatibility

Designed as an OEM-style replacement collet for use with ER16-series collet chucks and toolholders.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. The machine spindle must be fully stopped and the toolholder removed from the spindle before inserting or removing the collet. Use the correct ER16 collet nut and torque wrench rated for collet nut service - do not overtighten by hand or use non-rated tools. Verify runout at the tool tip with a dial indicator after clamping before resuming cuts.
