Kennametal 1013471 DA200 Collet Locknut

Product Description

The KENNAMETAL 1013471 is a collet locknut designed for use with the DA200 collet series. It secures the collet assembly within the toolholder body, maintaining precise axial positioning and clamping force during cutting operations. Weighing 0.0758 pounds, this locknut is a direct replacement component intended for CNC machining centers and milling applications where DA200-style toolholding is in use. Machinists and tool crib technicians responsible for toolholder maintenance and assembly are the primary installers of this part.

This locknut is used in shops running DA200 collet toolholders on CNC machining centers, vertical mills, and similar machine tool platforms. It is a replacement component suited for facilities that perform in-house toolholder service rather than sending assemblies out for repair. Coolant-through capability is not supported by this locknut.

Installation Notes

Installation is performed by a machinist or tool crib technician during toolholder servicing or collet replacement. The machine spindle should be powered down and locked out before disassembling any toolholder assembly. Use the appropriate DA200 spanner wrench to achieve proper locknut engagement — do not use pipe wrenches or improvised tools that may damage the locknut face or collet taper. Inspect the collet taper and bore for wear or damage before reassembly.
