Parlec ER32-0750 ER32 Collet 3/4 Inch

Product Description

The PARLEC ER32-0750 is an ER32 series collet designed to hold round shank tooling at a nominal 0.75 inch (3/4 inch) capacity. It seats into any ER32-compatible collet chuck and provides the clamping force needed for milling, drilling, and reaming operations on CNC machining centers and manual mills. The collet has an overall length of 1.574 inches and a minimum collet capacity of 0.711 inches, giving it a usable clamping range across that span. Machinists and tool-room technicians install this collet as a standard workholding component when running 3/4 inch shank tooling.

This collet is suited for use in production machining environments where repeatable tool runout and secure clamping are required. It fits ER32 collet chucks used on a wide range of machining centers, lathes with live tooling, and dedicated collet chuck holders. The ER32 series is one of the most widely adopted collet standards in the industry, making this collet a practical choice for shops that already run ER32 chuck bodies and need a 3/4 inch capacity position in their tooling inventory.

Key Features

• ER32 series collet standard for broad chuck compatibility
• 0.75 inch nominal capacity with a minimum clamping diameter of 0.711 inches
• Overall length of 1.574 inches for consistent projection and seating depth
• Compact overall diameter of 1.3 inches suited to standard ER32 chuck bores
• Single-piece construction typical of precision ground collets used in CNC toolholding

Compatibility

Designed as an OEM-style replacement or standard tooling addition for any ER32-compatible collet chuck system accepting 0.75 inch shank tooling.

Installation Notes

Installation is performed by a machinist or tool-room technician. Before installing or removing the collet, ensure the machine spindle is fully stopped and the chuck body is secure. Seat the collet into the ER32 chuck nut before threading the nut onto the chuck body - never install a collet directly into the chuck without first engaging it in the nut. Torque the nut using the appropriate ER collet wrench to ensure proper clamping force and runout performance.
