Accupro 588372 ER32 Collet 14 Mm

Product Description

The ACCUPRO 588372 is an ER32 series collet designed to hold 14 mm diameter tooling in ER32-compatible collet chucks. Collets in this series function by compressing radially when drawn into a tapered chuck body, creating a secure, concentric grip on cutting tools, drills, reamers, and other round-shank tooling. The ER32 standard is one of the most widely used collet systems in CNC machining, manual milling, and grinding operations. This collet is sized for 14 mm shanks and is used wherever precise tool holding and repeatable runout are required on production and job-shop machine tools.

The 588372 collet is suited for use in machining centers, CNC mills, manual knee mills, and toolroom lathes equipped with ER32 collet chucks. It handles turning, milling, drilling, tapping, and reaming operations where a 14 mm shank tool must be secured with consistent clamping force. Machinists and toolroom technicians working in manufacturing, maintenance, and repair environments are the primary installers of this component.

Key Features

• ER32 collet series for use with standard ER32 collet chucks
• 14 mm bore diameter for precise shank fit
• Radial compression design provides concentric, vibration-resistant tool clamping
• Lightweight at 0.8 pounds, minimizing added rotating mass
• Compatible with the widely standardized ER32 toolholding system used across multiple machine tool brands

Compatibility

Designed as a direct-fit replacement or addition for any machine tool equipped with a standard ER32 collet chuck body.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before changing collets, confirm the spindle is fully stopped and the machine is in a safe, locked-out state per shop lockout/tagout procedures. Seat the collet into the ER32 collet nut before inserting into the chuck body, then thread and torque the nut with the appropriate ER spanner wrench. Do not use a hammer or impact tool to seat or remove the collet.
