Accupro 588318 ER16 Collet 8 Mm

Product Description

The ACCUPRO 588318 is an ER16 series collet sized at 8 mm, designed to hold cutting tools securely in ER16-compatible collet chucks. Collets in this series work by compressing radially when tightened into a matched chuck nut, gripping the tool shank with consistent clamping force. The 588318 is machined to close tolerances, making it suitable for milling, drilling, and light boring operations on CNC machining centers and manual mills. Machinists and toolroom technicians are the primary installers of this type of workholding component.

This collet is intended for use in ER16 collet chucks across a range of machine tool applications, including CNC vertical machining centers, benchtop mills, and drill-tap machines. The 8 mm bore accepts standard 8 mm shank cutting tools. It is well suited for production and job-shop environments where repeatable tool runout and consistent grip are required for accurate part making.

Key Features

• 8 mm bore diameter for direct fit on 8 mm tool shanks
• Radial compression design provides even clamping force around the tool shank
• Suitable for milling, drilling, and light boring applications
• Single-piece package quantity — order one collet per unit

Compatibility

Designed for use with ER16-standard collet chucks and matching ER16 collet chuck nuts. Accepts 8 mm shank tooling. Confirm chuck series and nut compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing a collet, ensure the machine spindle is powered down and at a complete stop. Seat the collet into the chuck nut before threading the nut onto the chuck body — never tighten an empty collet. Use the correct ER16 torque wrench or spanner to achieve proper clamping without overloading the collet slots.
