Kennametal 1126072 Hex Drive Driver Ksem Modular Drill

Product Description

The KENNAMETAL 1126072 is a 2.5 mm hex drive driver designed for indexable tooling systems used in modular drilling applications. This driver provides the mechanical interface needed to seat, torque, and release indexable inserts and lock screws on KSEM-series modular drill toolholders. At 0.05 pounds, it is a compact, precision-fit hand tool kept in the toolcrib or on the machine for routine insert changes. The hex drive size of 2.5 mm is specific to the KSEM system hardware, and using the correct driver prevents cam-out damage to lock screw heads and ensures proper seating torque during insert replacement.

This driver is used in metalcutting environments where KSEM-series modular drills are in service on CNC machining centers, lathes with live tooling, or manual drill presses running indexable drill bodies. It is the specified driver for lock screw compatibility within the KSEM platform and is a standard consumable accessory for shops running modular drill programs. The blade length measures 11.61 decimal inches, giving the technician clearance to reach lock screws recessed in drill body pockets. Compatible screw reference is 364.012.

Compatibility

Designed for use with KENNAMETAL KSEM-series modular drill toolholders. Compatible with KSEM lock screws, including screw reference 364.012. Not intended for use outside the KSEM platform.

Installation Notes

Insert changes on indexable modular drills should be performed by a qualified machinist or toolroom technician with the machine powered down and spindle locked. Use only the designated 2.5 mm hex driver to engage lock screws — substituting an incorrect hex size risks rounding the screw socket and requiring extraction. Follow the toolholder manufacturer torque recommendations for the specific lock screw in use. Keep the driver clean and inspect the hex tip for wear periodically, as a worn driver tip can damage screw heads.
