Kennametal 3597589 Cap Screw Indexables TP9 Torx Plus M3x0.5

Product Description

The KENNAMETAL 3597589 is a cap screw designed for indexable tooling systems, specifically engineered for use with end mill bodies that require secure insert retention. This flat-head fastener uses a TP9 Torx Plus drive and features an M3x0.5 thread, providing the precise torque transfer and clamping force needed to keep cutting inserts firmly seated during machining operations. The screw is part of the KenFeed 2X Series and is compatible with the DT9IP key driver. Proper insert clamping screws are critical to dimensional accuracy, insert longevity, and safe chip control in milling applications.

This cap screw is used in indexable end mill bodies that accept M3x0.5 clamping screws with a Torx Plus drive interface. It is a maintenance and replacement consumable, typically purchased in quantity by machinists, toolroom technicians, and CNC operators managing insert tooling in production or job-shop environments. Because clamping screws are subject to wear and occasional galling, keeping replacement stock on hand minimizes downtime during insert changes.

Key Features

• TP9 Torx Plus drive for precise torque application and reduced cam-out during tightening
• M3x0.5 thread size for compatibility with standard indexable end mill bodies in the KenFeed 2X Series
• Flat head design seats flush within the insert pocket for unobstructed chip flow
• Compatible with DT9IP Torx Plus key driver
• Sold individually with a minimum order quantity of 10 units per order

Compatibility

Designed for use with KenFeed 2X Series indexable end mill bodies requiring an M3x0.5 cap screw with a TP9 Torx Plus drive. Requires the DT9IP key driver for installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Always ensure the spindle is stopped and the machine is in a safe, locked-out state before changing inserts or clamping screws. Use only the specified DT9IP Torx Plus driver to avoid stripping the drive recess. Inspect the threaded bore in the tool body for debris or damage before installing a replacement screw.
