Kennametal 1018891 Lock Pin Indexable Turning Tools

Product Description

The KENNAMETAL 1018891 is a lock pin designed to secure indexable inserts in turning tool holders. Lock pins apply clamping force directly to the insert bore, holding the cutting insert firmly in place during turning operations on a lathe. This part is installed by machinists and tool crib technicians as a replacement or spare component. The pin weighs approximately 0.0044 pounds, reflecting its compact form factor. Maintaining a reliable lock pin is essential for insert stability, accurate depth of cut, and safe chip control during metal-removal operations.

This lock pin is suited for use in indexable turning tool assemblies where a pin-style insert clamping system is specified. It is typically found in production turning, finish turning, and general-purpose lathe work across job shops, manufacturing facilities, and maintenance machine shops. Replace lock pins whenever wear, deformation, or loss of clamping tension is observed to prevent insert movement and tool damage.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Before servicing any toolholder, ensure the machine is powered down, the spindle is locked, and all stored energy is released per your facility lockout/tagout procedures. Use the correct driver or installation tool specified for the toolholder system to avoid deforming the pin. Inspect the pin seat and bore in the toolholder for wear or debris before installing a replacement pin.
