Parlec ER11-0059 ER11 Collet 0.059 in Capacity

Product Description

The PARLEC ER11-0059 is an ER11-series collet designed for precision tool holding in CNC machining and milling applications. It accepts a maximum tool shank diameter of 0.059 inches (1.50 mm) and has an overall length of 0.708 inches. The overall diameter measures 0.452 inches. ER collets are used to secure cutting tools, drills, reamers, and other round-shank tooling in compatible ER collet chucks. This collet is sized for small-diameter tooling and is well suited for fine machining work requiring accurate tool runout control.

This collet is intended for use in ER11 collet chucks found on CNC machining centers, milling machines, lathes with live tooling, and high-speed spindles. The ER11 series is a standard collet type used across a wide range of light-duty and precision machining setups. It is typically installed by machinists, toolroom technicians, and CNC operators working with small-diameter cutting tools in production or job-shop environments.

Installation Notes

ER collets are installed and removed using the appropriate collet chuck nut and spanner wrench for the ER11 series. Always power down and lock out the spindle before changing tooling. Do not exceed the rated collet capacity, as oversizing a collet can result in poor grip and tool pullout. Inspect the collet bore and chuck taper for chips or damage before seating.
