Parlec ER32-0472 ER32 Collet 0.4724 Inch 12mm

Product Description

The PARLEC ER32-0472 is an ER32 series collet designed for CNC machining centers, lathes, and milling machines that use ER32-style toolholding systems. With a collet size of 0.4724 inches (12.00 mm) and an overall length of 1.574 inches, this collet secures cutting tools and workpieces within the ER32 chuck bore. Minimum collet capacity is 0.4331 inches (11.0 mm), giving the collet a standard clamping range consistent with the ER32 specification. Machinists and CNC setup technicians install this collet as part of routine tooling changes or when building out a collet set for a specific bore diameter.

This collet is suited for production and job-shop environments running ER32-compatible toolholders on vertical or horizontal machining centers, lathes with live tooling, or manual milling machines. It is appropriate for applications requiring precise tool runout control and repeatable clamping across multiple setups. The 12.00 mm nominal size covers a commonly used shank diameter in both imperial and metric tooling inventories.

Compatibility

Designed for use with ER32-style collet chucks and toolholders that accept the ER32 collet series.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Ensure the spindle or toolholder is fully de-energized and the machine is in a safe lockout state before changing collets. Clean the collet bore and chuck taper before seating the collet to ensure proper contact and minimize runout. Use the appropriate ER32 collet nut and torque wrench rated for collet nut applications - do not overtighten by hand or with improvised tools.
