Accupro 777854 DA200 Collet Nut

Product Description

The ACCUPRO 777854 is a DA200 series collet nut used to secure collets in DA-style toolholders on CNC machining centers, lathes, and manual milling machines. The collet nut threads onto the nose of the toolholder and clamps the collet in place, maintaining accurate tool concentricity and axial position under cutting loads. Weighing 2.1 pounds, it is a direct replacement component for worn or damaged DA200 collet nuts. Installation and replacement are handled by machinists and toolroom technicians as part of routine toolholder maintenance.

The DA200 collet nut is suited for use in production and job-shop environments where DA200-series collets are in service. It is compatible with standard DA200 toolholder bodies used in both manual and CNC spindle applications. Machinists replacing worn collet nuts during tool setup or scheduled maintenance will find this a straightforward drop-in component for the DA200 platform.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Ensure the spindle is fully powered down and the machine is locked out before removing or installing any toolholder components. Use the appropriate spanner wrench for the DA200 collet nut to achieve proper seating — do not use impact tools or improvised wrenches, as this can damage the nut threads or toolholder body. Inspect collet and toolholder bore for wear or contamination before assembly.
