Hertel H82331687 Grooving Insert 0.089 in Solid Carbide

Product Description

The HERTEL H82331687 is a solid carbide grooving insert designed for precision external grooving and threading operations on CNC lathes and turning centers. Configured in the 16IR/EL style for right-hand cutting, it features a 0.089-inch cutting width and a maximum depth of cut of 0.089 inches. The insert is finished with a TiC and TiN multilayer coating to improve wear resistance and extend tool life. A 15-degree rake angle and 10-degree external relief angle support clean chip evacuation and reduced cutting forces. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.

This grooving insert is suited for external grooving applications on ferrous and non-ferrous workpiece materials in both production and precision turning operations. The 16IR/EL insert style fits compatible right-hand grooving toolholders designed for that insert seat geometry. The manufacturer grade HG220TR is targeted at applications within the maximum depth of cut range of 0.075 to 0.100 inches, making it appropriate for shallow-groove and snap-ring groove work on small-diameter parts. The 3/8-inch inscribed circle and 0.004-inch corner radius provide stable seating and a controlled edge profile.

Key Features

• Solid carbide substrate for rigidity and dimensional stability at elevated cutting temperatures
• TiC and TiN multilayer coating for improved wear resistance and surface finish
• 0.089-inch cutting width and 0.089-inch maximum depth of cut for precise shallow-groove work
• 15-degree rake angle with 10-degree external and 15-degree internal relief angles for efficient chip flow
• 0.004-inch corner radius for controlled edge geometry in tight-tolerance grooves
• Right-hand cut orientation; fits 16IR/EL-style toolholder seats

Compatibility

Designed for use in right-hand grooving toolholders with a 16IR/EL insert seat geometry. Verify toolholder seat dimensions and clamping style before installation to confirm proper fit.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine in a locked-out, powered-down state per applicable safety procedures. Use the correct torque wrench or insert key specified by the toolholder manufacturer when seating the insert clamp screw. Inspect the insert pocket for chips or debris before seating a new insert. Never exceed the rated maximum depth of cut, as doing so may cause insert fracture or toolholder damage.
