Kennametal 1712552 Threading Insert Iso 1.50mm Pitch 3/8 Ic

Product Description

The KENNAMETAL 1712552 is a solid carbide laydown threading insert designed for internal ISO thread cutting on CNC lathes and turning centers. Configured in a right-hand orientation with a 1.50mm pitch, it carries the KC5025 manufacturer grade and features a TiAlN coating applied via PVD process. The 3/8 inch (9.53mm) inscribed circle and 3.44mm thickness conform to standard LT16NR toolholder pockets. The CB chipbreaker geometry supports controlled chip flow during internal threading passes. Licensed machinists and CNC operators use this insert in production turning environments where consistent thread form and tool life are priorities.

This insert is suited for internal ISO-standard threading applications in ferrous and non-ferrous materials across light to medium cutting conditions. The TiAlN PVD coating provides thermal resistance and wear protection in interrupted or dry cutting scenarios. It fits 16NR-series toolholders designed for laydown insert geometry. Typical applications include threading bores in components such as hydraulic fittings, fastener bodies, and precision machined housings in manufacturing and job shop environments.

Key Features

• KC5025 carbide grade with TiAlN PVD coating for extended wear resistance
• Right-hand internal ISO thread form at 1.50mm pitch
• CB chipbreaker geometry for controlled chip evacuation during internal threading
• 3/8 inch (9.53mm) inscribed circle fits standard 16NR laydown toolholders
• Solid carbide substrate for dimensional stability and edge consistency
• 3.44mm insert thickness for secure seating in compatible pockets

Compatibility

Designed for use in 16NR-style laydown threading toolholders accepting a 3/8 inch inscribed circle insert with ISO internal thread geometry.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine before seating or replacing inserts. Use the correct torque driver for the clamping screw to avoid over-torquing and micro-fracturing the carbide edge. Confirm toolholder pocket condition and seating surface are clean and free of chips before inserting.
