Hertel H08694168 Threading Insert 32 Tpi 3/8 Inch Ic

Product Description

The HERTEL H08694168 is a laydown-style threading insert designed for external UN thread cutting at 32 threads per inch. Manufactured from solid carbide with a TiC/TiN coating, this insert delivers wear resistance and thermal stability in threading operations on a lathe or CNC turning center. The 3/8-inch inscribed circle and 0.1460-inch thickness conform to the 16ER insert style standard. It is suited for machinists and toolroom operators working with unified national thread forms in production or job-shop environments where consistent thread quality and tool life are priorities.

This insert is intended for right-hand external threading applications using the UN thread standard. The 16ER insert style seats in compatible laydown threading toolholders used on manual engine lathes and CNC turning machines. With 32 TPI, it is appropriate for fine-thread work on smaller-diameter fasteners, fittings, and precision mechanical components. The TiC/TiN finish supports performance across a range of steels and engineering alloys at typical threading surface speeds.

Key Features

• Solid carbide substrate with TiC/TiN coating for extended tool life in threading operations
• 16ER insert style for use in standard laydown threading toolholders
• 32 threads per inch for UN external fine-thread profiles
• Right-hand cutting geometry for conventional external thread turning
• 3/8-inch inscribed circle for precise seating and repeatability in the pocket
• Relief angle of 0 degrees consistent with laydown threading insert geometry

Compatibility

Designed as an OEM-style replacement threading insert for 16ER-style laydown threading toolholders used in external UN thread turning applications.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified toolholder pocket without overtightening. Verify insert seating and thread form with a thread gauge before resuming production cuts.
