Value Collection SC71000533 ER32 Collet Locknut

Product Description

The VALUE COLLECTION SC71000533 is an ER32 collet locknut designed to secure ER32 series collets in CNC machining and manual milling applications. The locknut threads onto the collet chuck nose to clamp the collet firmly in place, maintaining accurate tool runout and preventing collet movement during cutting operations. At 0.94 inches in height and 2.05 inches in diameter, this locknut fits the standard ER32 collet chuck thread specification. Machinists and toolroom technicians rely on properly torqued locknuts to hold cutting tools safely at operating speeds.

This locknut is suited for use on ER32 collet chucks found in CNC machining centers, manual knee mills, lathes with live tooling, and router spindles that accept the ER32 collet series. It is a common replacement or spare component for shops running high production cycles where locknuts see frequent removal and reinstallation. The part ships individually and is appropriate for both production environments and toolroom maintenance stock.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with collet chuck systems. Power down and de-energize the machine spindle completely before changing collet locknuts. Use the correct ER32 spanner wrench to torque the locknut evenly; never use substitute tools that can damage the locknut bearing face or collet groove. Inspect the locknut bearing surface and collet groove for wear or burrs before reuse.
