Parlec 5UMER11-0156 ER11 Collet 0.1563 Inch

Product Description

The PARLEC 5UMER11-0156 is an ER11 collet designed for precision tool holding in CNC machining and milling applications. It accepts a 0.1563-inch bore diameter and delivers a total indicator runout (TIR) of 0.0002 inches, making it suitable for close-tolerance work where concentricity matters. The collet measures 0.708 inches in overall length with an overall diameter of 0.452 inches. Machinists and toolroom technicians install this collet into compatible ER11 collet chucks to secure small-diameter cutting tools, drills, and end mills during machining operations.

This ER11 collet is used in light-duty CNC machining centers, milling machines, and high-speed spindle applications where a small collet size is required. It is particularly suited for holding small-shank tooling in production or toolroom environments. The compact ER11 series is common in bench-top CNC routers, engraving machines, and precision drilling stations where space is limited and tool-holding accuracy is critical.

Key Features

• ER11 series collet with 0.1563-inch bore for small-shank tooling
• 0.0002-inch TIR for high concentricity and precision runout control
• 0.708-inch overall length fits standard ER11 collet chuck pockets
• 0.452-inch overall diameter consistent with ER11 series geometry
• Lightweight at 0.06 pounds for use in high-speed spindle assemblies

Compatibility

Designed as an OEM-style replacement or standard collet for use with ER11 series collet chucks and compatible toolholder systems.

Installation Notes

ER11 collets are installed and removed by machinists or toolroom technicians using a collet chuck, collet nut, and appropriate spanner wrench. Power down and de-energize the spindle completely before changing tooling. Inspect the collet bore and chuck taper for chips or debris before seating the collet, as contamination will affect runout. Do not exceed the collet's rated clamping range when selecting tool shank diameters.
