Parlec 5UMER32-0196 ER32 Collet 0.1969 in 5mm

Product Description

The PARLEC 5UMER32-0196 is an ER32 series collet designed for precision tool holding in CNC machining and manual milling applications. It accepts a collet size of 0.1969 inches (5.00 mm) and delivers a total indicator runout (TIR) of 0.0002 inches, making it suitable for close-tolerance work where concentricity matters. The overall length is 1.574 inches. This collet is installed by machinists and toolroom technicians working with ER32-compatible collet chucks on lathes, machining centers, and tooling systems requiring repeatable clamping accuracy.

This collet is used in light to medium-duty machining environments where ER32 toolholding systems are standard. Typical applications include drilling, reaming, tapping, and end-mill holding in both production shops and job shops. The 5.00 mm nominal size suits metric tooling as well as imperial shanks at the 0.1969-inch decimal equivalent. It is a single-piece collet intended for direct installation into an ER32 collet chuck or collet block.

Key Features

• ER32 collet series for broad chuck compatibility
• 0.1969-inch (5.00 mm) collet size for metric and imperial tooling
• 0.0002-inch TIR for high concentricity and precision runout control
• 1.574-inch overall length for standard ER32 chuck seating
• Minimum collet capacity of 0.1575 inches (4.0 mm) for stepped or reduced-shank tooling

Compatibility

Designed for use with ER32-compatible collet chucks and toolholding systems accepting the ER32 collet series.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with ER collet systems. Before installing or removing the collet, ensure the spindle is fully stopped and the machine is powered down. Clean the collet, nut, and chuck bore before assembly to prevent contamination that affects TIR. Do not overtighten the collet nut beyond the chuck manufacturer's specified procedure, as this can distort the collet and reduce clamping accuracy.
