Value Collection SC09287756 ER16 Collet Chuck

Product Description

The VALUE COLLECTION SC09287756 is an ER16 collet chuck designed for use in CNC machining centers, milling machines, and drill presses where precise tool holding is required. The chuck accepts ER16-series collets with a clamping capacity range of 0.019 to 0.394 inches, covering a wide variety of end mills, drills, and reamers. A 1-inch straight shank provides direct spindle compatibility with standard tool holders. Total indicator runout (TIR) is rated at 0.0004 inches, delivering the concentricity required for finish milling and precision boring operations. Actuation is performed with a wrench via the standard ER lock nut. This chuck is installed by machinists and CNC setup technicians in production and job-shop environments.

This collet chuck is suited for light to medium-duty cutting applications in both manual and CNC machining setups. The ER16 collet system is widely used in high-speed spindle applications where compact tool projection and secure clamping are priorities. The 7.2-inch shank length provides reach for setups requiring extended tool access. No through-coolant capability is present on this chuck, so flood or mist coolant must be directed externally at the cutting zone.

Compatibility

Designed as an OEM-style replacement or new-installation collet chuck compatible with ER16-series collets. Fits machine spindles and tool holders accepting a 1-inch straight shank.

Installation Notes

Installation and tool changes should be performed by a qualified machinist or CNC setup technician with the spindle fully powered down and locked out per facility lockout/tagout procedures. Use the appropriate ER wrench and spanner to torque the lock nut to the collet manufacturer's specification. Inspect the collet bore and chuck taper for chips or damage before seating the collet. Do not exceed the rated collet capacity range, as oversized tooling will damage the collet and chuck body.
