Techniks 23108 ER8 Collet Nut

Product Description

The TECHNIKS 23108 is an ER8 collet nut designed to secure ER8 series collets in compatible tool holders. The collet nut threads onto the nose of the holder and applies clamping force to the collet, locking cutting tools in place during machining operations. Proper collet nut engagement is critical for runout performance and tool retention. This nut is a direct replacement or spare component for shops running ER8 tooling systems and is installed by machinists and toolroom personnel.

The ER8 collet nut is suited for use in small-diameter ER8 collet chucks found in CNC machining centers, manual mills, lathes, and high-speed spindles where ER8 tooling is specified. Its compact size makes it appropriate for light-duty precision work involving small shank cutting tools. It is commonly stocked as a replacement part in production environments where collet nuts are subject to regular wear from frequent tool changes.

Installation Notes

Installation and removal should be performed by a qualified machinist using the appropriate ER collet nut spanner wrench. Ensure the spindle or tool holder is fully de-energized and at rest before servicing any collet components. Inspect collet and holder threads for damage or contamination before installing the nut. Do not use impact tools or substitute spanners, as this can damage the nut and holder threads.
