Parlec 5UMER11-0093 ER11 Collet 0.0938 Inch Bore

Product Description

The PARLEC 5UMER11-0093 is an ER11 collet designed for precision tool holding in CNC machining and milling applications. With a 0.0938-inch bore capacity and a total indicator runout (TIR) of 0.0002 inches, this collet delivers the tight concentricity required for high-accuracy cutting operations. The overall assembly length (OAL) is 0.708 inches, and the overall diameter is 0.452 inches. Machinists and tooling technicians rely on ER11 collets for securing small-diameter end mills, drills, and reamers in ER-style collet chucks.

This collet is suited for use in light-duty CNC machining centers, CNC routers, and manual milling machines equipped with ER11 collet chuck systems. The compact ER11 size class is commonly selected for small-diameter tooling where space constraints in the spindle or workpiece area are a factor. It is installed by tooling technicians and CNC machinists in both production shop and job-shop environments handling precision metal, composite, or plastic workpieces.

Key Features

• 0.0938-inch bore capacity for small-diameter cutting tool shanks
• 0.0002-inch TIR for tight concentricity and accurate tool runout control
• ER11 collet standard for broad compatibility with ER11 chuck bodies
• 0.708-inch OAL supports compact tooling setups
• 0.452-inch overall diameter fits standard ER11 collet nut and chuck configurations

Compatibility

Designed as an OEM-style replacement or direct fitment collet for ER11-standard collet chucks used in CNC machining and milling tool-holding systems.

Installation Notes

ER collets are installed by qualified machinists or tooling technicians. Always power down and lock out the spindle before seating or removing a collet. Insert the collet into the collet nut before threading the nut onto the chuck body, and use a calibrated torque wrench with the appropriate ER11 spanner to seat the collet correctly. Do not exceed the recommended clamping torque for the ER11 collet size, and inspect the collet bore and taper surfaces for wear or damage before each use.
