Kennametal 1712614 Threading Insert 11 Tpi 3/8 in Ic KC5025

Product Description

The KENNAMETAL 1712614 is a solid carbide laydown threading insert designed for right-hand external Whitworth thread cutting on CNC and manual lathes. Manufactured to insert style 16ER, this insert carries the KC5025 grade designation and features a PVD-applied TiAlN coating that supports elevated cutting speeds and extends tool life in steel and stainless applications. The chipbreaker designation CB promotes controlled chip formation during threading passes. With an inscribed circle of 3/8 inch (9.53 mm) and a thickness of 0.1430 inch (3.44 mm), the insert seats into standard 16ER toolholders. Machining professionals and CNC operators specify this insert for precision threaded-component production.

This insert is applied to external Whitworth thread forms at 11 threads per inch, a pitch specification common in BSW and BSP fastener and fitting manufacturing. Typical use cases include threading mild steel, alloy steel, and similar ferrous materials on production or job-shop lathes. The PVD TiAlN coating keeps cutting-edge temperatures in check during continuous threading cycles, making this insert appropriate for both light-production and high-volume threading operations where consistent thread form accuracy is required.

Key Features

• Solid carbide substrate with PVD TiAlN coating for wear resistance and thermal stability
• KC5025 grade optimized for threading steel and ferrous alloys
• Right-hand external Whitworth thread form at 11 TPI
• CB chipbreaker geometry for controlled chip evacuation during threading passes
• 3/8 inch inscribed circle seats into standard 16ER toolholders
• Insert style 16ER for broad toolholder compatibility

Compatibility

Designed as an OEM-style threading insert for use in standard 16ER-style laydown threading toolholders compatible with external Whitworth thread applications.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the insert. Torque the insert clamping screw per the toolholder manufacturer specifications using the appropriate torx or hex key. Verify thread form and pitch accuracy with a thread gauge after the first pass before committing to a production run.
