Hertel H08697765 Threading Insert 10 Tpi 3/8 in Ic Un

Product Description

The HERTEL H08697765 is a laydown threading insert designed for right-hand internal UN threading operations on CNC lathes and manual threading equipment. Built from solid carbide with a TiC/TiN coating, this insert delivers consistent thread form geometry at 10 threads per inch (TPI) with a 3/8 inch inscribed circle (IC) and a 0.146 inch thickness. The HG630TR grade is suited for threading ferrous and non-ferrous materials where tool life and surface finish consistency are priorities. Machinists and tool room technicians working in production or job shop environments rely on inserts like this for repeatable internal UN thread profiles on bores and fittings.

This insert is sized for laydown-style threading toolholders that accept the 16IR insert style. It is appropriate for internal threading applications in general machining, fluid system component manufacturing, and precision part production where UN thread standards are required. The right-hand cutting geometry suits standard bore threading passes. At 10 TPI, this insert covers common UN thread pitches used in industrial fastener and connector applications. This is a per-piece item sold within a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate with TiC/TiN coating for wear resistance on threading passes
• 10 TPI cutting geometry for UN internal thread standard
• Right-hand cutting orientation for standard bore threading
• 3/8 inch inscribed circle fits 16IR laydown toolholder pockets
• 0.146 inch insert thickness for positive seating in compatible holders
• Relief angle of 0 degrees for laydown-style clamping systems

Compatibility

Designed for use in 16IR-style laydown threading toolholders that accept a 3/8 inch IC insert with a 0.146 inch thickness and a zero-degree relief angle.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key per the toolholder manufacturer's clamping screw specification, and ensure the insert seats fully and evenly in the pocket before securing. Inspect the insert and holder pocket for chips or debris before each use to prevent premature insert breakage or thread form error.
