Techniks 53116 ER16 Collet Nut

Product Description

The TECHNIKS 53116 is an ER16 collet nut designed to secure ER16 collets within compatible toolholders on CNC machining centers, lathes, and milling machines. The nut threads onto the toolholder nose and clamps the collet firmly in place, maintaining accurate tool runout during cutting operations. Weighing 0.1 pounds, it is a lightweight but precision-critical component in any ER16 toolholding setup. This part does not support coolant-through configurations. It is installed and replaced by machinists and CNC setup technicians as part of routine toolholding maintenance.

The 53116 collet nut is suited for shops running ER16 collet chucks in standard dry or flood-coolant environments where coolant-through delivery is not required. It is a direct-fit replacement for worn or damaged ER16 collet nuts and is sold individually, making it practical to replace single components without purchasing a full collet set.

Key Features

• ER16 collet series compatibility for precise collet clamping
• Secures collets in ER16 toolholders for accurate, repeatable tool holding
• Non-coolant-through design suits standard flood or dry machining setups
• Lightweight at 0.1 pounds for easy handling during tool changes
• Sold individually for targeted replacement without excess inventory

Compatibility

Designed as a replacement collet nut for ER16 series collet chucks and toolholders using the standard ER16 collet interface.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle drive before changing or tightening collet nuts. Use the appropriate ER16 collet nut wrench and toolholder spanner to achieve proper clamping torque without over-tightening. Inspect the nut threads and collet seating surface for wear or damage before each installation.
