Kennametal 1018989 Lock Pin Indexable Turning Tools

Product Description

The KENNAMETAL 1018989 is a lock pin designed to secure inserts in indexable turning tool holders. Lock pins maintain positive insert seating during cutting operations, preventing insert movement under the lateral and axial forces generated in turning applications. This component is a small but critical part of the tooling assembly — a loose or worn lock pin leads to insert chatter, dimensional inaccuracy, and premature insert failure. Machinists and toolroom technicians working with indexable turning setups install and replace lock pins as part of routine tooling maintenance. The 1018989 ships as a single pin per package.

This lock pin is intended for use in indexable turning tool holders where insert retention is achieved through a pin-and-clamp or pin-style locking mechanism. It is suited for CNC turning centers and manual lathe applications in production and job-shop environments. Indexable turning tools are used across a wide range of materials and cut types, and maintaining a supply of replacement lock pins is standard practice in any shop running high-utilization turning programs.

Compatibility

Designed as an OEM-style replacement lock pin for KENNAMETAL indexable turning tool holders that use a pin-style insert retention system. Consult the specific tool holder documentation to confirm pin geometry and fit before ordering.

Installation Notes

Lock pin replacement is typically performed by a machinist or toolroom technician as part of indexable tooling maintenance. Before servicing the tool holder, ensure the machine is powered down, the spindle is locked, and the tool is secured in a bench vise or appropriate fixture. Use the correct pin driver or punch to remove and install lock pins without damaging the holder bore. Do not force an incorrectly sized pin into the holder, as this can damage the locking seat and compromise insert retention.
