Parlec ERS32-0275 ER32 Collet 7mm

Product Description

The PARLEC ERS32-0275 is an ER32 series collet designed for use in CNC machining centers, milling machines, and other rotating spindle equipment that accepts ER32 toolholding systems. With a 7 mm bore size and an overall length of 1.574 inches, this collet provides controlled radial clamping force on cutting tools, drill bits, and round-shank workholding tooling. The collet operates at a clamping pressure rating of 1800, delivering consistent grip across the tool shank. Machinists and toolroom technicians rely on ER-series collets for their wide clamping range, ease of change-out, and compatibility with standard ER nuts and chucks.

This collet is suited for precision metal-cutting applications in both production and job-shop environments. It fits ER32 collet chucks mounted in machining center spindles, lathe turrets, or collet chuck holders used in horizontal and vertical milling setups. The 7 mm bore accommodates metric-shank cutting tools and drill bits commonly used in general machining, die-and-mold work, and light to medium material removal operations. Installation and tool changes are performed by toolroom machinists or CNC setup technicians.

Key Features

• ER32 collet series - compatible with standard ER32 chucks and clamping nuts
• 7 mm bore size for metric-shank cutting tools and drill bits
• Overall length of 1.574 inches for consistent tool projection control
• 1800 clamping pressure rating for secure tool grip during rotation
• Compact form factor supports close-clearance and multi-axis machining setups

Compatibility

Designed as an OEM-style replacement or direct-fit collet for ER32 toolholding systems accepting a 7 mm bore collet.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the spindle drive before inserting or removing collets from any chuck body. Seat the collet fully into the ER32 chuck before threading on the clamping nut, and torque the nut using the appropriate ER collet wrench - do not use impact tools on collet nuts. Inspect the collet bore and seating taper for chips or damage before each use.
