Parlec ERS16-0157 ER16 Collet 4 Mm Bore

Product Description

The PARLEC ERS16-0157 is an ER16 series collet designed for use in ER16-compatible collet chucks on CNC machining centers, milling machines, and similar precision machine tools. This collet accepts a 4 mm bore diameter and has an overall length of 1.082 inches with an overall diameter of 0.669 inches. The clamping pressure rating of 1800 ensures consistent, repeatable tool holding suited to production environments. Toolroom technicians and CNC setup personnel install this collet as part of standard tooling assemblies.

This collet is appropriate for light to medium-duty milling, drilling, reaming, and tapping operations where a 4 mm tool shank must be secured in an ER16 chuck. It fits standard ER16 collet chucks used across a wide range of vertical and horizontal machining centers in both job shop and production settings. The compact ER16 form factor makes it well suited to applications requiring close tool-to-fixture clearance.

Key Features

• 1.082 inch overall length for compact tooling assemblies
• 0.669 inch overall diameter consistent with ER16 chuck specifications
• 1800 clamping pressure rating for secure, repeatable grip
• Compatible with standard ER16 collet chucks used on common machining platforms

Compatibility

Designed as a standard ER16 series collet for use with ER16-compatible collet chucks on CNC and manual machine tool platforms.

Installation Notes

Installation is performed by qualified toolroom or CNC setup personnel. The collet must be seated fully into the ER16 collet chuck nut before threading onto the chuck body. Torque the collet nut with the appropriate ER16 spanner wrench to achieve proper clamping force - do not use pipe wrenches or improvised tools. Inspect the collet bore and chuck taper for chips or contamination before assembly to ensure runout is within acceptable limits.
