Accupro 588847 ER16 Collet 0.31 Inches

Product Description

The ACCUPRO 588847 is an ER16 series collet designed for use in CNC machining centers, milling machines, and router spindles that accept ER16 collet chucks. This collet holds workpieces and cutting tools with a nominal capacity of 0.31 inches (decimal: 0.3100 inches) and a minimum collet capacity of 0.281 inches, providing a reliable clamping range suitable for end mills, drills, and similar round-shank tooling. Machinists and tool room technicians install ER16 collets as part of standard tooling setups. The part ships individually and is intended as a direct replacement or supplemental collet for existing ER16 chuck systems.

The ACCUPRO 588847 is suited for light to medium-duty machining applications where ER16 toolholding is specified. Typical use cases include precision milling, drilling, and engraving operations on CNC machining centers and manual mills equipped with ER16-compatible spindles or collet chucks. The 0.31-inch capacity makes it a common choice for holding standard fractional and metric shank cutting tools within that size range. This collet is packaged individually and is appropriate for both production environments and job shop tooling inventories.

Installation Notes

ER16 collets are installed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before installing or removing collets. Ensure the collet, chuck bore, and nut are clean and free of chips or debris before seating. Follow the machine and chuck manufacturer torque specifications for the collet nut to avoid over-tightening or under-tightening.
