Techniks 04211-7/64 ER11 Collet 0.708 in Oal

Product Description

The TECHNIKS 04211-7/64 is an ER11 series collet designed for use in CNC machining centers, milling machines, and high-speed spindle applications. With an overall length of 0.7080 inches and a total indicated runout (TIR) of 0.000200 inches, this collet delivers the dimensional accuracy required for precision cutting tool holding. It is sized to the ER11 standard, making it compatible with ER11 collet chucks and toolholders. Machinists and CNC operators install this collet to securely grip cutting tools, drill bits, and end mills in light-duty to medium-duty machining operations.

This collet is suited for use in precision machining environments where tight runout tolerances are critical to surface finish and tool life. ER11 collets are commonly used in high-speed routing, engraving, drilling, and milling applications found in both production shops and maintenance machining settings. The compact ER11 form factor makes this collet a standard choice for smaller spindle assemblies and toolholding systems requiring consistent, repeatable clamping.

Key Features

• ER11 collet series for use with standard ER11 chucks and toolholders
• 0.000200 inch TIR for high-precision tool holding and reduced runout
• Overall length of 0.7080 inches fits compact spindle assemblies
• Designed for consistent, repeatable clamping in CNC and manual machining operations

Compatibility

Designed as an OEM-style replacement and standard fitment collet for ER11 series collet chucks and compatible toolholding systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before installing or removing the collet, power down the spindle and confirm all motion has stopped. Use the appropriate ER11 collet nut and spanner wrench to seat and torque the collet chuck assembly per the toolholder manufacturer guidance. Inspect the collet bore and chuck taper for debris or wear before each use to maintain runout performance.
