Parlec ER16-0137 ER16 Collet 0.1378 in Capacity

Product Description

The PARLEC ER16-0137 is an ER16-series collet designed to hold cutting tools and workpieces with a nominal bore capacity of 0.1378 inches (3.50 mm). It is used in ER16-compatible collet chucks mounted in CNC machining centers, milling machines, lathes, and drilling units. The collet clamps the toolshank securely by collapsing uniformly under chuck-nut torque, providing concentric grip across the clamping range. With an overall length of 1.082 inches and a minimum collet capacity of 0.098 inches (2.49 mm), the ER16-0137 suits light to medium toolholding applications where precise runout control matters. Machinists and toolroom technicians are the primary installers.

This collet fits standard ER16 collet chucks used in high-speed spindle applications across job shops, production machining facilities, and toolroom environments. The ER16 series is a widely adopted international standard, making this collet compatible with ER16 chucks from a broad range of machine tool manufacturers. It is suited to residential and commercial shop environments wherever ER16 toolholding is specified.

Compatibility

Designed as a direct-fit replacement or addition for ER16-standard collet chucks used in CNC and manual machine tool spindle applications.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before installing or removing the collet, confirm the spindle is fully stopped and the machine is locked out per shop lockout/tagout procedures. Insert the collet into the ER16 chuck body until it seats in the retention groove, then thread on the collet nut and torque to the chuck manufacturer's specification using an ER collet wrench. Inspect the collet for nicks, cracks, or out-of-round wear before each use, as a damaged collet will compromise grip and runout performance.
