Parlec ER32-0551 ER32 Collet 0.5512 Inch

Product Description

The PARLEC ER32-0551 is an ER32 series precision collet designed for use in ER32-compatible toolholding systems on CNC machining centers, milling machines, and lathes. It accepts workpieces and cutting tools up to 0.5512 inches (14.00 mm) in diameter, with a minimum collet capacity of 0.5118 inches (13.0 mm). The overall length is 1.574 inches. Machinists and toolroom technicians install this collet into an ER32 chuck or collet block to achieve accurate, repeatable tool clamping across a wide range of milling, drilling, reaming, and tapping operations.

This collet is suited for production and job-shop environments where ER32 toolholding is the standard. It fits any ER32-compatible chuck regardless of machine brand, making it a practical replacement or additional collet for shops running CNC mills, manual mills, or turning centers equipped with ER32 chucks. The 14.00 mm nominal collet size covers common imperial and metric cutting tool shanks in its clamping range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing the collet, ensure the machine spindle is fully stopped and the control is in an e-stop or locked-out state per OSHA lockout/tagout procedures. Seat the collet fully into the ER32 chuck before threading on the clamping nut to prevent collet damage. Do not overtighten the clamping nut beyond the chuck manufacturer's specified torque range; use a proper ER spanner wrench rather than improvised tools to avoid damaging the nut or collet.
