Hertel H08696163 Threading Insert 16 Tpi Un Carbide

Product Description

The HERTEL H08696163 is a laydown threading insert designed for external UN thread cutting at 16 threads per inch. Built from solid carbide with a TiC/TiN coating, this insert delivers consistent thread form geometry and surface finish on ferrous and non-ferrous materials. The 16ER insert style seats in standard 16ER toolholders for right-hand external threading operations. With a 3/8 inch inscribed circle and 0.146 inch thickness, this insert is sized for medium turning centers and CNC lathes. It is installed and changed by machinists and CNC operators working in production or job shop environments.

This insert is suited for external UN thread turning on CNC lathes and turning centers where consistent 16 TPI thread profiles are required. The right-hand orientation and 16ER insert style make it appropriate for standard external threading passes on shaft diameters and threaded fastener features. The HG630TR grade with TiC/TiN finish supports general-purpose threading across a range of workpiece materials including steel and alloy materials. This insert is typically used in moderate-speed, finish threading applications where edge retention and coating adhesion matter.

Key Features

• Solid carbide construction with TiC/TiN coating for wear resistance and edge retention
• 16 TPI UN thread standard for common inch-series external threads
• 16ER insert style fits standard 16ER compatible toolholders
• Right-hand cutting orientation for conventional external threading
• 3/8 inch inscribed circle with 0 degree relief angle for laydown seating
• 0.146 inch insert thickness for stable, repeatable indexing in the pocket

Compatibility

Designed for use in standard 16ER external threading toolholders that accept laydown-style inserts with a 3/8 inch inscribed circle and 0 degree relief angle.

Installation Notes

Threading inserts are installed and indexed by machinists using a torx or hex key per the toolholder manufacturer specification. Ensure the machine spindle is at a full stop and the toolholder pocket is clean and free of chips before seating the insert. Confirm insert orientation matches the required thread hand before starting a threading cycle. Follow the toolholder manufacturer guidelines for clamping and insert retention.
