Parlec ERS16-0375 ER16 Collet 0.375 Inch

Product Description

The PARLEC ERS16-0375 is an ER16 series collet designed for use in ER16-compatible collet chucks and toolholding systems. It holds workpieces or cutting tools at a clamping diameter of 0.375 inches (3/8 inch) and has an overall length of 1.082 inches with an overall diameter of 0.669 inches. The collet operates at a rated clamping pressure of 1800, making it suitable for precision machining applications. Machinists and CNC operators working with milling machines, machining centers, and similar equipment install this collet for secure, concentric tool holding in production and job-shop environments.

The PARLEC ERS16-0375 is used in machine shops and manufacturing facilities where ER16 collet chucks are specified. It is appropriate for both light-duty and moderate-duty cutting applications involving end mills, drills, reamers, and other round-shank tooling up to 0.375 inches in diameter. The compact ER16 format is common in smaller spindles and high-speed machining setups where minimizing overhang and maintaining rigidity are priorities.

Key Features

• ER16 collet series for use with standard ER16-compatible chucks
• 0.375 inch (3/8 inch) clamping diameter for common round-shank tooling
• 1.082 inch overall length for low-profile tool holding
• 0.669 inch overall diameter consistent with ER16 envelope
• Rated clamping pressure of 1800 for secure tool retention

Compatibility

Designed as a direct-fit replacement for ER16 collet positions in standard ER16-compatible collet chucks and toolholding systems accepting 0.375 inch shank tooling.

Installation Notes

Installation is performed by qualified machinists or CNC setup personnel. The collet should be seated fully into the ER16 collet chuck nut before threading onto the chuck body. Ensure the spindle is powered down and locked out before changing collets. Do not exceed the rated clamping torque specified by the chuck manufacturer, and inspect the collet bore and seating surface for debris or damage before each use.
