Parlec ER16-0039 ER16 Collet 0.0394 Inch

Product Description

The PARLEC ER16-0039 is an ER16 series collet designed for precision workholding in CNC machining centers, milling machines, and high-speed spindle applications. It accepts a nominal collet size of 0.0394 inches (1.00 mm) with a minimum collet capacity of 0.0197 inches (0.5 mm), allowing it to grip small-diameter tooling securely. The overall length measures 1.082 inches and the overall diameter is 0.669 inches. Machinists and tool-room technicians install this collet wherever repeatable, accurate tool clamping is required on ER16-compatible toolholders and chucks.

This collet is suited for light-duty precision machining work involving small-shank cutting tools such as drills, end mills, and reamers in the 0.5 mm to 1.0 mm diameter range. It is appropriate for use in production and job-shop environments running ER16-standard spindle noses or toolholding chucks. Applications include engraving, micro-drilling, and fine-feature milling operations where small tool diameters and tight runout tolerances are required.

Key Features

• ER16 collet series for compatibility with standard ER16 chucks and toolholders
• Nominal size of 0.0394 inches (1.00 mm) for small-diameter tooling
• Minimum collet capacity of 0.0197 inches (0.5 mm) for micro-tool clamping
• Overall length of 1.082 inches fits standard ER16 chuck depth
• Overall diameter of 0.669 inches matches ER16 taper geometry

Compatibility

Designed as an OEM-style replacement or standard component for use with ER16-series collet chucks and toolholding systems accepting the ER16 taper standard.

Installation Notes

Installation is performed by qualified machinists or tool-room technicians. Before changing collets, ensure the machine spindle is fully stopped and the toolholder is removed from the spindle or the machine is in a safe, locked-out state per applicable shop safety procedures. Use the correct ER16 spanner wrench and collet nut to seat and torque the collet properly. Avoid forcing an undersized or oversized tool shank into the collet, as this can damage the collet bore and reduce clamping accuracy.
