Hertel 16IR14UNHG225TR Threading Insert 14 Tpi Solid Carbide

Product Description

The HERTEL 16IR14UNHG225TR is a laydown-style threading insert designed for internal UN thread cutting at 14 threads per inch. Manufactured from solid carbide with a PVD-applied TiAlN coating, it delivers consistent thread form and wear resistance in demanding turning applications. The insert has a 3/8 inch (0.3750 inch decimal) inscribed circle and a thickness of 0.1460 inches. It is suited for use in CNC lathes and manual turning centers where precise internal threading is required. Installation is performed by qualified machinists following standard insert toolholder procedures.

This insert is configured for right-hand internal threading to the UN thread standard at 14 TPI. It fits laydown-style insert toolholders accepting the 16IR insert style. Typical applications include threading bores in ferrous and non-ferrous workpieces in production machining environments. The TiAlN coating extends tool life in higher-temperature cutting conditions. Sold individually, with a minimum order quantity of 10 units per order.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• PVD TiAlN coating for elevated thermal and oxidation resistance
• 14 TPI UN internal thread form, right-hand orientation
• 3/8 inch inscribed circle (0.3750 inches decimal) laydown geometry
• Insert style 16IR for use in compatible laydown-style toolholders
• Manufacturer grade HG225TR for consistent performance across batch production

Compatibility

Designed for use in laydown-style insert toolholders that accept the 16IR insert style. Confirm toolholder seat geometry and clamping compatibility before installation.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before seating or replacing the insert. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not over-torque the clamping screw. Verify thread pitch and insert orientation against the workpiece drawing before commencing the threading cycle.
