Techniks 23111 ER11 Hex Collet Locknut

Product Description

The TECHNIKS 23111 is an ER11 hex collet locknut designed to secure ER11 series collets in compatible toolholders during machining operations. The hex profile allows technicians to apply controlled torque with a standard spanner wrench, ensuring repeatable clamping force on cutting tools. This locknut does not support coolant-through configurations. It is a direct-replacement component used in CNC machining centers, milling machines, and high-speed spindle applications where consistent tool runout and retention are critical to cut quality and tool life.

This locknut is suited for use in machine shops and production environments running ER11 collet toolholders. The ER11 collet system is commonly found in compact spindles and smaller-diameter toolholding setups. Machinists and CNC setup technicians install this component during routine toolholder maintenance, collet replacement, or when a worn or damaged locknut needs to be swapped out to restore proper clamping performance.

Key Features

• Hex profile for use with a standard ER spanner wrench for controlled torque application
• Compatible with ER11 collet series toolholders
• No coolant-through passage - suited for dry or flood coolant setups where through-spindle coolant is not required
• Direct replacement component for maintaining ER11 toolholder assemblies

Compatibility

Designed as a direct-fit replacement locknut for ER11 series collet toolholders.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the spindle before removing or installing any toolholder component. Use the correct ER11 spanner wrench to tighten the locknut - do not use pipe wrenches or improvised tools that can damage the hex or collet seating surface. Follow the toolholder manufacturer's recommended torque procedure to avoid over-clamping the collet.
