Accupro 588316 ER16 Collet 7 Mm

Product Description

The ACCUPRO 588316 is an ER16 series collet sized at 7 mm, designed for use in CNC machining centers, milling machines, lathes, and high-speed spindle applications. It provides a precision clamping interface between the spindle toolholder and the cutting tool shank, transmitting torque while maintaining concentricity under load. The collet operates within the ER16 standard, which dictates the outer taper geometry and clamping range. With a clamping pressure rating of 1000, it delivers consistent grip force suitable for light to moderate metal removal operations. Machinists and toolroom technicians install this collet as part of routine tooling changeovers or when setting up new operations on ER16-compatible toolholders.

This collet fits ER16 collet chucks and toolholders used in benchtop and production CNC equipment. The 7 mm bore accommodates tool shanks at that diameter, making it a direct fit for a wide range of end mills, drills, and reamers with 7 mm shanks. It is suited for both production shop environments and toolroom use where repeatable runout and secure clamping are required across multiple setups.

Key Features

• ER16 collet series — matches ER16 standard taper geometry for direct chuck compatibility
• 7 mm bore size for precise clamping of 7 mm shank cutting tools
• 1000 pressure rating supports consistent grip force during machining operations
• Compact form factor suitable for high-speed spindle and CNC milling applications
• Packaged as a single unit for individual tooling replacement or setup

Compatibility

Designed as an OEM-style replacement collet for ER16-standard collet chucks and toolholders used in CNC milling, drilling, and turning applications.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always power down and lock out the spindle before removing or installing collets. Seat the collet fully into the nut before threading onto the chuck body, and use the appropriate ER16 torque wrench or spanner to secure the nut — do not use makeshift tools that could damage the collet seat. Inspect the collet bore and taper for chips or debris before each use to ensure concentricity and safe clamping.
