Parlec ER16-0406 ER16 Collet 0.406 Inch

Product Description

The PARLEC ER16-0406 is an ER16 series collet designed for precision workholding in CNC machining centers, milling machines, and other rotating spindle applications. It accepts tool shanks up to 0.406 inches in diameter and has a minimum collet capacity of 0.3666 inches, providing a usable clamping range suited to a variety of cutting tool shank sizes. Overall length is 1.082 inches. The overall outside diameter measures 0.669 inches. Machinists and tool crib technicians install this collet into compatible ER16 collet chucks to achieve accurate, concentric tool holding during light to medium cutting operations.

This collet is used in machine shop environments wherever ER16-style collet chucks are in service. Typical applications include vertical machining centers, knee mills, and drill/tap machines running end mills, drills, reamers, or taps with shank diameters in the ER16 clamping range. It is well suited to both production and toolroom settings where repeatable tool runout and secure clamping are required.

Installation Notes

Installation of ER16 collets is performed by qualified machinists or tool crib personnel. Before inserting or removing a collet, ensure the machine spindle is fully stopped and the control is in an e-stop or lockout/tagout state per applicable safety procedures. Seat the collet into the collet chuck nut before threading onto the holder body, then tighten with the appropriate ER spanner wrenches to the chuck manufacturer's specified procedure. Do not use pipe wrenches or makeshift tools, as these can damage the collet or chuck threads and compromise runout accuracy.
