Accupro 587316 ER16 Collet 0.314 Inch 8.00mm

Product Description

The ACCUPRO 587316 is an ER16 series collet designed for precision CNC machining and milling applications. It accepts a nominal shank diameter of 0.314 inches (8.00mm) with a minimum collet capacity of 0.275 inches (7.0mm), giving the tool a clamping range suited to small-diameter end mills, drills, and reamers. The collet holds a total indicator runout (TIR) of 0.01mm, making it appropriate for applications where concentricity directly affects surface finish and tool life. Machinists and CNC setup technicians install this collet into compatible ER16 collet chucks as part of standard tooling changeouts.

This collet is used in vertical and horizontal machining centers, CNC mills, and drill-tap machines that accept ER16 collet chucks. It is suited to light-duty to medium-duty cutting operations in job shops, production machining environments, and tool rooms. The 0.01mm TIR rating makes it a reliable choice when running small carbide tooling where runout control is a factor in tool longevity and part accuracy.

Key Features

• ER16 collet series for use in standard ER16 chucks
• Nominal collet size of 0.314 inches (8.00mm)
• Minimum collet capacity of 0.275 inches (7.0mm)
• 0.01mm TIR for consistent concentricity and reduced tool runout
• Single-piece package quantity for individual replacement or tooling builds

Compatibility

Designed for use with ER16 series collet chucks in CNC machining and milling setups that accept the ER16 collet standard.

Installation Notes

Installation is performed by qualified machinists or CNC technicians. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before changing collets. Clean the chuck bore and collet taper seating surfaces before installation to maintain the rated TIR. Use the appropriate ER16 collet nut and torque wrench rated for the chuck manufacturer's specified clamping procedure.
