Parlec ER32-0787 ER32 Collet 0.7874 Inches

Product Description

The PARLEC ER32-0787 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other spindle-driven equipment that accept the ER32 collet system. With a collet size of 0.7874 inches (20.00 mm) and a minimum collet capacity of 0.748 inches (19.0 mm), it securely clamps round shanked cutting tools and workholding stock within its clamping range. The overall length is 1.574 inches. Machinists and tool room technicians install this collet when setting up high-precision toolholding assemblies that demand consistent runout control and repeatable grip force.

This collet is suited for production machining environments where the ER32 standard is already in use. Typical applications include end mill holding, drill chuck replacement setups, reamer holding, and tap holding in both vertical and horizontal machining centers. The ER32 system is widely adopted in job shops and manufacturing facilities running both light and medium-duty cutting operations. Installation requires a compatible ER32 collet chuck body and the appropriate ER32 clamping nut.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Before changing collets, power down the spindle and confirm the machine is in a safe, locked-out state per applicable lockout/tagout procedures. Insert the collet into the ER32 chuck body before threading on the clamping nut, and tighten the nut with the appropriate ER32 collet spanner wrench to the chuck manufacturer's specification. Inspect the collet for wear, cracks, or debris before each use to maintain runout accuracy and tool retention force.
