Parlec 5UMER16-0093 ER16 Collet 0.0938 Inch

Product Description

The PARLEC 5UMER16-0093 is an ER16 series collet designed for precision toolholding in CNC machining and milling applications. It accepts a collet size of 0.0938 inches (3/32 inch) with a minimum collet capacity of 0.0735 inches, making it suitable for small-diameter cutting tools and drills. The collet delivers a total indicator runout (TIR) of 0.0002 inches, supporting tight-tolerance work where concentricity directly affects part quality and tool life. Overall length is 1.082 inches. This collet is installed by machinists and CNC setup technicians in production and job-shop environments.

ER16 collets are widely used in high-speed spindles, collet chucks, and toolholding systems across vertical machining centers, CNC lathes with live tooling, and manual milling machines. The 0.0938-inch bore size is a common selection for small end mills, reamers, drills, and taps. This collet is suited for both light finishing passes and standard production runs where a secure, concentric tool grip is required at smaller diameters.

Key Features

• ER16 collet series for compatibility with standard ER16 collet chucks and toolholders
• 0.0938 inch (3/32 inch) collet size for small-diameter tooling
• 0.0002 inch TIR for precision concentricity in close-tolerance applications
• 1.082 inch overall length fits within standard ER16 chuck depth requirements
• Minimum collet capacity of 0.0735 inches accommodates a range of shank diameters below nominal size

Compatibility

Designed as an OEM-style replacement and standard fitment collet for ER16 collet chucks and toolholding systems accepting the ER16 series specification.

Installation Notes

ER16 collets are installed by machinists or CNC technicians. Always power down and lock out the machine spindle before changing collets. Inspect the collet and chuck bore for chips, burrs, or damage before seating the collet, as contamination will increase runout beyond the rated TIR. Use the appropriate ER16 collet nut and tighten with a spanner wrench to the chuck manufacturer's specified procedure - do not overtighten by impact methods.
