Hertel H08697369 Threading Insert 12 Tpi 3/8 in Ic Un

Product Description

The HERTEL H08697369 is a solid carbide laydown threading insert designed for right-hand internal UN threading operations. Manufactured to the 16IR insert style, it carries the HG630TR grade designation and features a TiC/TiN multilayer coating that improves wear resistance and extends tool life in production threading applications. The insert is sized at a 3/8 inch inscribed circle (0.3750 inches) and measures 0.146 inches thick, with a relief angle of 0 degrees. It cuts at 12 threads per inch and is suited for use in CNC lathes and turning centers where consistent thread form and dimensional accuracy are required. Installation and operation are handled by machinist and toolroom personnel.

This insert is intended for internal UN thread forms at 12 TPI in typical machining environments, including job shops, production facilities, and maintenance toolrooms. The right-hand cutting geometry is suited for standard bore threading in ferrous and non-ferrous materials where a TiC/TiN-coated solid carbide grade provides reliable performance across a range of surface speeds and material hardnesses. The 16IR laydown style provides stable seating in compatible laydown insert toolholders.

Key Features

• Solid carbide substrate for rigidity and dimensional stability in threading passes
• TiC/TiN multilayer coating for improved wear and heat resistance
• 12 TPI cutting geometry for UN internal thread standard
• 3/8 inch inscribed circle (0.3750 inches) laydown insert form factor
• Right-hand cutting direction for standard internal bore threading
• 0 degree relief angle for laydown-style toolholder compatibility

Compatibility

Designed as an OEM-style threading insert for use in laydown-style internal threading toolholders accepting the 16IR insert style. Specific toolholder compatibility should be verified against the toolholder manufacturer's insert specification chart before use.

Installation Notes

Threading inserts of this type are installed and indexed by qualified machinists following machine tool manufacturer guidelines. Ensure the machine spindle is fully stopped and all stored energy is released before changing or indexing inserts. Use the correct torque wrench or insert-clamping key as specified by the toolholder manufacturer to seat the insert properly. Inspect the insert pocket for chips or debris before installation to ensure accurate seating and thread form.
