Kennametal 1867353 L-key TP15 Torx Plus Drive

Product Description

The KENNAMETAL 1867353 is an L-key wrench designed for tightening and loosening indexable insert screws on boring bars and similar toolholders. It uses a TP15 Torx Plus drive, which provides a more secure engagement and reduced cam-out compared to standard hex drives. This tool is a bench-level accessory used by machinists and toolroom technicians during insert changes, setup, and maintenance of indexable cutting tools. At 0.05 pounds, it is a compact, lightweight hand tool that belongs in any CNC or manual lathe setup kit where Kennametal indexable tooling is in use.

This L-key is specifically suited for boring bar applications using compatible Kennametal toolholder styles and screw systems. It is used during routine insert indexing and replacement cycles on the shop floor or at the machine. Compatible hardware includes STC screws and shim screws. Compatible screw part numbers include KMSP315IP, KMSP415IP, and STCM1115IP. Compatible insert geometries include SN..322 and SN..432 series. Toolholder style compatibility is confirmed for the A-DSKN-KC style.

Installation Notes

This tool is installed and used by machinists, toolroom technicians, or CNC setup personnel. Before changing or indexing inserts, ensure the machine is powered down and the spindle is locked or secured per shop safety procedures. Use the L-key only with the correct TP15 Torx Plus screw head to avoid drive damage. Do not use extensions or additional leverage beyond the L-key arm to apply torque, as insert screws have manufacturer-specified torque limits.
