Parlec ER16-0196 ER16 Collet 0.1969in 5.00mm

Product Description

The PARLEC ER16-0196 is an ER16 series precision collet sized at 0.1969 inches (5.00mm) for use in ER16-compatible collet chucks on CNC machining centers, manual mills, and high-speed spindle toolholding systems. With an overall length of 1.082 inches and an overall diameter of 0.669 inches, this collet provides secure, concentric clamping of round shank cutting tools, drill bits, and end mills. The minimum collet capacity is 0.1575 inches (4.0mm), giving the collet a working clamping range suited to light-to-medium tooling. Installation is performed by qualified machinists and CNC setup technicians during tool changes or workholding configuration.

This collet is used in machine shop environments where ER16 toolholding is standard, including production machining, prototype work, and general-purpose milling and drilling operations. The ER16 standard is widely adopted across benchtop and full-size machining centers, making this collet a common consumable for shops running small-diameter tooling. It is appropriate for both light-duty and precision applications where accurate tool runout is required.

Installation Notes

Installation is performed by machinists or CNC setup technicians using the appropriate ER16 collet nut and spanner wrench. Power down and lock out the spindle drive before seating or removing any collet. Insert the collet into the chuck body before threading the collet nut to avoid damaging the collet retaining groove. Inspect the collet bore and chuck taper for chips or debris before each use to maintain tool runout within acceptable limits.
