Hertel H08702599 Laydown Threading Insert 16ERG60 HG330TR

Product Description

The HERTEL H08702599 is a solid carbide laydown threading insert designed for right-hand external thread cutting operations. Carrying the 16ER insert style and grade HG330TR, it features a TiC/TiN coating that improves wear resistance and surface finish during threading. This insert produces a partial profile 60-degree thread form and covers a thread range of 14 to 8 TPI, with a corresponding metric pitch range of 1.75 to 3.00 mm. With a 3/8-inch inscribed circle and a thickness of 0.146 inches, it seats into standard 16ER laydown toolholders. Machinists and CNC operators install this insert on lathes and turning centers for external thread generation on ferrous and non-ferrous workpieces.

This insert is suited for external threading on turning centers, manual lathes, and CNC lathes in production and job-shop environments. The 60-degree partial profile geometry makes it applicable across a wide range of unified and metric thread standards within its TPI range. The solid carbide substrate with TiC/TiN finish performs well in general-purpose threading of steel and similar materials. It is typically used by machinists and tooling specialists performing thread-turning operations where consistent thread geometry and tool life are priorities.

Key Features

• Solid carbide substrate with TiC/TiN coating for improved wear resistance
• 16ER laydown insert style compatible with standard 16ER toolholders
• Right-hand external partial profile 60-degree thread form
• Thread range of 14 to 8 TPI (1.75 to 3.00 mm pitch)
• 3/8-inch inscribed circle with 0.146-inch thickness for precise seating
• Zero-degree relief angle for laydown insert geometry

Compatibility

Designed for use in standard 16ER laydown threading toolholders. Verify that the toolholder accepts a 3/8-inch inscribed circle insert with a 0.146-inch thickness before installation.

Installation Notes

This insert is installed and replaced by machinists or tooling technicians on CNC or manual turning equipment. Power down and de-energize the machine before changing inserts. Use the appropriate torx or hex key per the toolholder manufacturer's specification to secure the insert clamp. Inspect the insert pocket for debris or damage before seating the new insert to ensure proper contact and alignment.
