Accupro 784815 ER16 Collet 0.216 Inch

Product Description

The ACCUPRO 784815 is an ER16 series collet designed for use in CNC machining centers, milling machines, and compatible toolholding systems. With a collet size of 0.216 inches and a minimum collet capacity of 0.188 inches, this collet secures cutting tools and round-shank workholding tooling within the ER16 collet chuck system. The overall length is 1.063 inches (27.0 mm). Weighing 0.05 pounds, it is a compact, precision-ground component installed by machinists and toolroom technicians. The ER16 series is a widely used standard in precision toolholding for light to medium-duty machining operations.

This collet is suited for use in ER16-compatible collet chucks mounted in CNC mills, manual mills, routers, and similar machine spindles. It is appropriate for production shops, toolrooms, and maintenance machining environments where consistent tool runout and clamping force are required. The single-piece package quantity makes it suitable for individual replacement or adding to an existing ER16 collet set.

Installation Notes

Installation is performed by machinists or toolroom technicians using an ER16 collet chuck and the appropriate spanner wrench. Always ensure the machine spindle is fully powered down and locked out before inserting or removing collets. Inspect the collet bore and chuck taper for debris or damage before seating. Do not overtighten the collet nut beyond the chuck manufacturer specifications.
