Parlec ERS32-0787 ER32 Collet 20 Mm

Product Description

The PARLEC ERS32-0787 is an ER32 series collet designed for use in CNC machining centers, milling machines, and toolholding systems that accept the ER32 collet standard. With a collet size of 20 mm and an overall length of 1.574 inches, this collet clamps workpieces and cutting tools securely within an ER32 collet chuck. It delivers consistent gripping force and concentricity for precision material removal operations. Rated at 1800 psi clamping pressure, it is suited for demanding production environments. Machinists and CNC operators install these collets as part of standard toolholding setups across a wide range of machining applications.

This collet is used in machine shops running CNC mills, manual mills, and drilling operations that require ER32 toolholding. The 20 mm bore size accommodates cutting tools and round-shank tooling at that diameter. It is appropriate for both production and job-shop settings where repeatable, accurate tool clamping is required. Licensed machinists and CNC technicians perform installation and changeover as part of routine tooling setup.

Key Features

• ER32 collet series for broad compatibility with ER32 chucks and toolholders
• 20 mm collet bore size for secure clamping of 20 mm shank tooling
• 1.574 inch overall length for standard ER32 chuck seating
• 1800 psi clamping pressure rating for stable grip under cutting loads
• Compact design at 0.33 pounds for easy handling during tooling changes

Compatibility

Designed as an OEM-style replacement or standard tooling component for use with ER32 collet chucks and ER32-compatible toolholding systems.

Installation Notes

Installation is performed by qualified machinists or CNC operators. The machine spindle must be powered down and brought to a full stop before any collet or tooling change. Use a properly sized ER32 collet wrench and chuck spanner to seat and torque the collet nut - do not use makeshift tools that may damage the collet taper or chuck threads. Inspect the collet bore and chuck taper for chips or debris before seating to maintain concentricity and clamping performance.
