Kennametal 1018971 Lock Pin Indexable Turning Tools

Product Description

The KENNAMETAL 1018971 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 position during turning operations on CNC lathes and manual turning centers. This pin is a small but critical component — insert movement during a cut leads to dimensional error, surface finish problems, and potential insert fracture. The 1018971 weighs 0.0132 pounds, reflecting the compact, precision form factor typical of indexable tooling hardware. Installation and replacement are performed by machinists and toolroom technicians as part of routine insert change procedures.

Lock pins of this type are used in metal-cutting turning operations across production machining, job shop, and maintenance repair environments. They are installed in indexable turning tool holders where the insert is retained through a center-bore pin-lock clamping system rather than a top clamp or lever. This configuration is common on ISO and ANSI-style turning holders used for external turning, facing, and profiling operations on ferrous and non-ferrous workpieces.

Key Features

• Pin-lock design secures indexable insert in the tool holder bore during turning operations
• Compact, precision form factor compatible with indexable turning tool holder systems
• Lightweight at 0.0132 pounds — does not add mass or clearance concerns to the holder assembly
• Sold individually per package — allows single-unit replacement without purchasing a full hardware kit
• Manufactured by KENNAMETAL, a recognized supplier of metalcutting tooling components

Compatibility

Designed for use with KENNAMETAL indexable turning tool holders that use a pin-lock insert retention system. Confirm holder model and pin specification against KENNAMETAL tooling documentation before ordering to ensure correct fit.

Installation Notes

Lock pin replacement is performed by qualified machinists or toolroom personnel. Before servicing any turning tool holder, ensure the machine spindle is fully stopped, the program is halted, and the machine is placed in a safe state per your facility lockout/tagout procedure. Use the correct Torx or hex key driver as specified by the tool holder manufacturer — do not over-torque the pin, as this can damage the insert bore or the pin threads. Inspect the pin seat and bore for chips or debris before seating the new pin.
