Kennametal 1126021 Hex Driver Indexables 1.5mm Ksem

Product Description

The KENNAMETAL 1126021 is a 1.5 mm hex driver designed for indexable tooling systems used in metalworking and machining applications. This driver is built specifically for tightening and removing lock screws on modular drill assemblies, providing the correct drive geometry to prevent fastener damage during insert changes. Sized at 1.5 mm hex, it fits the KSEM modular drill series and is compatible with the corresponding lock screw hardware. Licensed machinists, toolroom technicians, and CNC setup personnel typically keep this driver on hand as a dedicated tool for insert indexing and drill head maintenance.

This driver is intended for use with KSEM series modular drill holders in production and job-shop environments. It is specifically matched to the lock screw hardware used in KSEM drill assemblies, making it a required accessory for proper insert installation and removal. Compatible insert types include KSEM 0625, KSEM 0719, and TPGX 1102ZPR. The driver supports efficient toolchange routines at the machine or bench and eliminates the use of incorrect or improvised hex tools that can strip fastener heads.

Installation Notes

This driver is used by machinists and toolroom technicians during indexable insert changes on modular drill assemblies. Always ensure the spindle is stopped and the machine is locked out before accessing the toolholder for insert service. Use the correct 1.5 mm hex driver to avoid rounding the lock screw head, which can make removal difficult and require screw replacement. Do not use power tools with this driver unless the toolholder manufacturer explicitly permits it.
