Hertel H08701773 Threading Insert 16IR 48-16 Tpi Solid Carbide

Product Description

The HERTEL H08701773 is a laydown threading insert designed for internal threading operations on CNC lathes and turning centers. It features a 16IR insert style with a solid carbide substrate and a TiC/TiN finish coating applied to improve wear resistance and tool life during high-speed threading passes. The insert cuts a 60-degree partial profile thread form, covering a range of 48 to 16 threads per inch (TPI), which corresponds to a metric pitch range of 0.50 to 1.50 mm. The inscribed circle measures 3/8 inches (0.3750 inches decimal) and the insert thickness is 0.1460 inches. Right-hand cutting orientation. Installed and changed by machinists and CNC toolroom technicians.

This insert is suited for internal threading applications in production and job-shop environments where a single insert must cover a broad TPI range without a toolholder changeover. The 60-degree partial profile form is appropriate for Unified National (UN), metric, and other 60-degree thread families when a full-profile finish is not required. The TiC/TiN coating provides a balance of hardness and lubricity, making the insert effective in steel and other ferrous workpiece materials. The 16IR geometry fits standard laydown threading toolholders designed for that insert style.

Key Features

• Solid carbide substrate with TiC/TiN coating for wear resistance in ferrous materials
• 60-degree partial profile form covers Unified National and metric 60-degree thread families
• Wide TPI range of 48-16 (0.50 to 1.50 mm pitch) reduces insert changes across jobs
• Right-hand, internal cutting orientation for bore and hole threading operations
• 16IR insert style fits standard laydown threading toolholders
• Insert thickness of 0.1460 inches with zero-degree relief angle for rigid, laydown seating

Compatibility

Designed for use in standard laydown threading toolholders that accept the 16IR insert style. Verify toolholder seat geometry and clamping system compatibility before ordering.

Installation Notes

Insert changes must be performed with the machine powered down and the spindle fully stopped. Use the correct torque wrench and insert-clamping screw specified by the toolholder manufacturer when seating the insert. Inspect the toolholder pocket and locating surfaces for chips or wear before installing a new insert. Confirm thread form, hand, and TPI setting in the CNC control before running the first part.
