Hertel 16IR10UNHG225TR Threading Insert 10 Tpi 3/8 in Ic

Product Description

The HERTEL 16IR10UNHG225TR is a solid carbide laydown threading insert designed for internal UN thread cutting on CNC lathes and turning centers. Coated with TiAlN via a PVD process, it delivers heat resistance and extended tool life in demanding threading operations. The insert features a 10 TPI thread pitch, a 3/8-inch (0.3750-inch) inscribed circle, and a thickness of 0.146 inches. It is sized for right-hand internal threading and is suited for machinists and toolroom professionals running production or job-shop threading passes on steel and similar materials.

This insert is used in internal threading applications conforming to UN thread standards. It fits toolholders accepting the 16IR insert style and is appropriate for residential machine shops, manufacturing facilities, and production environments where consistent thread form and surface finish are required. The TiAlN coating supports higher cutting speeds and improves wear resistance compared to uncoated carbide, making it a practical choice for moderate to high-volume threading runs.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiAlN coating applied via PVD process for heat resistance and extended insert life
• 10 TPI thread pitch conforming to UN thread standard
• Right-hand cut geometry for standard internal threading direction
• 3/8-inch (0.3750-inch) inscribed circle — 16IR insert style
• Thickness of 0.146 inches for precise laydown seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for toolholders accepting the 16IR laydown threading insert style with UN internal thread geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before seating or replacing the insert. Use the correct torque screwdriver or clamp key specified by the toolholder manufacturer — do not overtighten the clamping screw. Verify insert orientation and seating before resuming cutting operations.
