Kennametal 1020289 Tg/pg 75 Collet Locknut

Product Description

The KENNAMETAL 1020289 is a collet locknut designed for use with TG/PG 75 collet tooling systems. The locknut secures the collet within the toolholder body, maintaining precise axial position and clamping force during cutting operations. At 1 pound, it is a solid, purpose-built component intended for machine shop environments where toolholder integrity directly affects surface finish, tool life, and dimensional accuracy. Installation and replacement are performed by machinists and CNC setup technicians as part of routine toolholder maintenance.

This locknut is specified for TG/PG 75 series collet toolholders, which are commonly found in vertical and horizontal machining centers, drill presses, and CNC milling applications. The TG/PG 75 collet series is a widely adopted standard in production machining environments, and the locknut is a direct wear and maintenance item that requires periodic replacement to maintain consistent clamping performance.

Key Features

• Designed specifically for TG/PG 75 collet series toolholders
• Maintains collet clamping force and axial positioning during high-speed cutting
• Direct replacement component for standard TG/PG 75 toolholder maintenance
• Compact form factor suited for production machining environments

Compatibility

Compatible with TG/PG 75 series collet toolholders. Verify collet series designation on the toolholder body before ordering to confirm fitment.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before removing or installing any toolholder component. Use the appropriate spanner wrench sized for the TG/PG 75 locknut to avoid damage to the nut or collet body. Do not over-tighten; follow the toolholder manufacturer's recommended assembly procedure.
