Parlec ERS32-0708 ER32 Collet 18 Mm Bore

Product Description

The PARLEC ERS32-0708 is an ER32 series collet designed for use in ER32-compatible collet chucks on CNC machining centers, manual mills, and lathes. It accepts a nominal 18 mm bore diameter, providing a secure clamping grip on round shanked cutting tools, drills, reamers, and end mills. The collet measures 1.574 inches overall length with a 1.3 inch overall diameter and weighs 0.33 pounds. PARLEC collets are a standard choice for machinists and tool crib technicians who require consistent runout performance and reliable clamping force across production tooling setups.

This collet is suited for use in machine shops running ER32 toolholding systems on vertical and horizontal machining centers as well as manual milling machines. It is appropriate for both roughing and finishing operations where 18 mm shank tooling is required. The ER32 series is one of the most widely used collet standards in the industry, making this collet a common replacement and spare component for high-volume production and job shop environments alike.

Key Features

• 18 mm nominal bore diameter for secure clamping of 18 mm shank tools

• 1.574 inch overall length for correct seating in ER32 holders
• 1.3 inch overall diameter matches ER32 chuck geometry
• Lightweight at 0.33 pounds, minimizing added mass in the spindle

Compatibility

Designed as an OEM-style replacement collet for use in standard ER32 collet chuck toolholders across CNC and manual machining applications.

Installation Notes

ER32 collets are installed and removed by qualified machinists or tool crib personnel using an ER32 collet nut and the appropriate spanner wrench. Always ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Inspect the collet bore and the chuck taper for chips, wear, or damage before seating the collet. Do not exceed the rated clamping pressure for the collet series, and replace collets that show visible cracking, wear on the slotted fingers, or loss of grip force.
