Parlec ERS40-0750 ER40 Collet 0.75 Inch

Product Description

The PARLEC ERS40-0750 is an ER40 series collet designed to hold round workpieces and cutting tools with a 0.75-inch shank diameter. It fits into ER40-standard collet chucks and tool holders, providing consistent clamping force for milling, drilling, tapping, and turning operations. With an overall length of 1.811 inches and a clamping pressure rating of 1800, this collet delivers reliable tool retention for production and job-shop environments. Machinists and toolroom technicians install this collet as part of a precision workholding setup on CNC and manual machine tools.

This collet is suited for use in machining centers, lathes, milling machines, and multi-axis CNC equipment that accept ER40 collet chucks. It accommodates a 3/4-inch (0.7500-inch) tool or workpiece shank and is a standard fitment in shops requiring repeatable runout performance across a range of cutting tool diameters. Typical applications include end mill holding, drill chucking, tap holding, and reamer retention in both production and prototype machining.

Key Features

• 1800 clamping pressure rating for secure tool retention
• Suitable for milling, drilling, tapping, and reaming operations

Compatibility

Designed as an OEM-style replacement and standard fitment for ER40 collet chucks and tool holder systems that accept the ER40 collet series.

Installation Notes

Installation is performed by machinists or toolroom technicians using an ER40 collet nut and the appropriate collet chuck wrench. Always clean the collet taper and chuck bore before seating the collet to ensure accurate runout. Do not exceed the rated clamping torque for the collet nut, and inspect the collet for wear or damage before each use. Worn or damaged collets should be replaced before returning the tool holder to service.
