Kennametal 1692103 Threading Insert Iso External Rh

Product Description

The KENNAMETAL 1692103 is a solid carbide laydown threading insert designed for cutting external ISO threads on CNC lathes and turning centers. Carrying the KC5010 grade with a PVD-applied TiAlN coating, it delivers wear resistance and thermal stability during high-speed threading operations. The insert is configured for right-hand external threading at a 2.00 mm pitch and features a 3/8-inch (9.53 mm) inscribed circle with a thickness of 0.1430 inches (3.44 mm). Machinists and CNC operators install this insert in compatible LT16 series toolholders for precision thread-form production on steel and alloy workpieces.

This insert is suited for external ISO-standard threading applications in production machining environments, including job shops and manufacturing cells running ferrous and hardened materials. The CB chipbreaker geometry promotes chip control during threading passes. The PVD TiAlN coating makes it appropriate for dry or minimal-coolant cutting strategies where heat resistance is critical. Minimum order quantity for this insert is 10 pieces, supplied in individual unit packaging.

Key Features

• KC5010 carbide grade with PVD TiAlN coating for wear and heat resistance
• Right-hand external ISO thread configuration at 2.00 mm pitch
• 3/8-inch (9.53 mm) inscribed circle for LT16 series toolholder compatibility
• CB chipbreaker geometry for controlled chip evacuation during threading
• Solid carbide substrate for dimensional stability and edge integrity
• Insert thickness of 0.1430 inches (3.44 mm) with 0.1551-inch hole diameter for secure seating

Compatibility

Designed for use in LT16 series laydown threading toolholders accepting a 3/8-inch inscribed circle insert with a right-hand external ISO thread geometry. Consult the toolholder manufacturer specifications to confirm seat and clamping compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key to seat and torque the clamping screw per the toolholder manufacturer guidelines - do not overtighten, as carbide inserts are brittle and susceptible to fracture under excessive clamping force. Inspect the insert pocket and seating surface for chips or debris before placing the insert.
