Kennametal 3593911 Cap Screw Indexables TP7 Torx Plus

Product Description

The KENNAMETAL 3593911 is a cap screw designed for indexable tooling systems, specifically engineered to secure cutting inserts in end mill applications. This screw uses a Torx Plus drive interface at size TP7, requiring a DT7IP key or compatible driver for installation and removal. At 0.01 pounds, it is a precision fastener built for the clamping forces and vibration environments common in CNC and manual milling operations. Machinists and tooling technicians who maintain indexable end mill toolholders rely on this type of hardware to achieve consistent insert seating and clamping integrity during cutting cycles.

This cap screw is used in indexable end mill toolholders where insert retention hardware must meet tight dimensional and drive-interface standards. It is suited for shop environments running production milling, die and mold work, or general-purpose metal removal where indexable insert tooling is standard. Replacement of worn or damaged clamping screws with the correct OEM-specified part is critical to maintaining insert position and surface finish consistency. The TP7 Torx Plus drive reduces cam-out risk compared to standard hex drives, making it a preferred interface in high-cycle tooling maintenance.

Key Features

• TP7 Torx Plus drive interface reduces cam-out during insert changes
• Compatible with DT7IP key or driver for precise torque application
• Designed for indexable end mill insert retention applications
• Lightweight at 0.01 pounds, precision-formed for consistent clamping geometry
• UNSPSC Code 31161500 for procurement and catalog classification

Compatibility

Designed as a replacement cap screw for indexable end mill toolholders requiring a TP7 Torx Plus drive screw with DT7IP key compatibility. Consult your toolholder documentation to confirm screw size and thread specification before ordering.

Installation Notes

Installation and replacement of indexable insert clamping screws should be performed by a qualified machinist or tooling technician. Always remove the toolholder from the spindle and ensure the machine is in a safe, de-energized state before servicing insert hardware. Use only the specified DT7IP Torx Plus driver to avoid drive recess damage and apply torque per the toolholder manufacturer specifications. Inspect the screw threads and seating surface for wear or contamination before reinstalling.
