Parlec 5UMER16-0236 ER16 Collet 0.2362 in 6.00mm

Product Description

The PARLEC 5UMER16-0236 is an ER16 series collet designed for precision workholding in CNC machining centers, milling machines, and high-speed spindle applications. It holds a collet size of 0.2362 inches (6.00 mm) with a total indicated runout (TIR) of 0.0002 inches, making it suitable for close-tolerance toolholding where concentricity directly affects surface finish and tool life. The overall length is 1.082 inches and the overall diameter is 0.669 inches. Machinists and tooling specialists install this collet as part of an ER16 collet chuck assembly in production and job-shop environments.

This collet is used in light-duty to medium-duty cutting applications including drilling, reaming, milling, and tapping where ER16 toolholding systems are specified. The 0.2362-inch bore accommodates round-shank cutting tools and workpieces at that diameter. Typical installation environments include CNC machining centers, manual mills, and bench-top spindle units equipped with ER16 collet chucks. It suits both production-floor and maintenance-shop use where repeatable toolholding accuracy is required.

Key Features

• ER16 collet series for compatibility with standard ER16 collet chucks
• 0.2362 inch (6.00 mm) collet bore for precise round-shank tool retention
• 0.0002 inch TIR for high concentricity and minimal runout during cutting
• Minimum collet capacity of 0.1969 inches (5.0 mm) for range clamping
• Compact 1.082 inch overall length suited to tight-clearance spindle setups

Compatibility

Designed as a direct-fit replacement or standard component for ER16 collet chuck systems requiring a 0.2362 inch bore collet.

Installation Notes

Installation is performed by tooling specialists or qualified machinists. Power down and lock out the spindle drive before inserting or removing collets. Seat the collet fully into the ER16 collet nut before threading onto the chuck body to prevent collet damage. Inspect the collet bore and chuck taper for chips or contamination prior to assembly to maintain rated TIR.
