Product Description

The PARLEC ER32-0630 is an ER32-series precision collet designed for use in ER32-compatible toolholders and collet chucks. It provides a bore size of 0.6299 inches (16.00 mm) with a minimum collet capacity of 0.5906 inches (15.0 mm), giving it a usable clamping range suited to a variety of round-shank cutting tools. The overall length is 1.574 inches. This collet is installed by machinists and toolroom technicians in milling, drilling, and tapping operations where accurate, repeatable tool runout is required.

The ER32-0630 fits standard ER32 collet chucks and toolholders used on CNC machining centers, manual mills, and drill presses. Its 16.00 mm nominal size makes it appropriate for metric and equivalent imperial-diameter end mills, drills, reamers, and taps. It is a single-piece collet used in both production and job-shop environments where ER32 toolholding is the established standard.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before changing collets, power down and lock out the machine spindle per OSHA lockout/tagout procedures. Seat the collet into the nut before inserting the toolholder, ensure the tool shank is clean and free of burrs, and torque the collet nut to the toolholder manufacturer's specification using an appropriate ER32 collet nut wrench. Never drive the nut without a tool shank engaged, as this can distort the collet body.
