Kennametal 2259981 Cap Screw Indexables TP15 Torx Plus

Product Description

The KENNAMETAL 2259981 is a TP15 Torx Plus cap screw designed to secure indexable inserts in milling and turning toolholders. These screws are a critical fastener in indexable tooling assemblies, holding cutting inserts firmly in their pockets during metal removal operations. The TP15 Torx Plus drive provides positive engagement with the tightening key, reducing the risk of cam-out and fastener damage during insert changes. Weighing approximately 0.004 pounds each, these screws are compact precision fasteners intended for use by machinists and toolroom professionals in CNC and manual machining environments.

This cap screw is used in indexable milling and turning toolholders that accept TP15 Torx Plus insert-clamping screws. It is suited for production machining environments where inserts are changed frequently and fastener reliability directly impacts cycle time and toolholder longevity. Typical applications include face mills, turning tools, boring bars, and other indexable tooling platforms that use this screw specification for insert retention.

Compatibility

Designed for use with indexable milling and turning toolholders that require a TP15 Torx Plus cap screw for insert retention. Confirm drive type and thread specification against existing toolholder documentation before ordering.

Installation Notes

Installation of indexable insert screws should be performed by a qualified machinist or toolroom technician. Always ensure the toolholder and machine spindle are fully stopped and the machine is locked out before changing inserts or tightening clamping screws. Use the correct TP15 Torx Plus key to avoid rounding the drive recess. Do not use thread-locking compounds unless explicitly specified by the toolholder manufacturer.
