The VALUE COLLECTION 204-1604 is an ER16 series collet designed to hold workpieces or cutting tools with a nominal shank diameter of 0.0622 inches (1/16 inch). It delivers a total indicator runout (TIR) of 0.0005 inches, providing the concentricity required for precision CNC milling, drilling, and boring operations. The collet seats into a standard ER16 collet chuck and is tightened with a matching nut to grip tooling securely. Machinists, toolroom technicians, and CNC operators install these collets as standard consumable toolholding components on milling machines, machining centers, and router spindles.
This collet is suited for light-duty precision work involving small-diameter end mills, drills, reamers, and router bits with a 1/16-inch shank. It is appropriate for both production and job-shop environments where tight runout control is needed at small diameters. The ER16 series is a widely adopted collet standard across vertical machining centers and compact CNC routers in both industrial and prototyping settings.
Designed as a standard ER16-series collet for use with any ER16-compatible collet chuck and clamping nut across CNC milling machines, machining centers, and router spindles accepting the ER16 collet standard.
Installation requires an ER16 collet chuck and the corresponding collet nut. Power down and lock out the spindle before inserting or removing the collet. Seat the collet fully into the chuck before threading the nut, and use a calibrated collet wrench and chuck wrench to achieve proper clamping — never overtighten by impact. Inspect the collet bore and chuck taper for chips or contamination before each use, as debris will degrade runout performance.
