Hertel H82331562 Grooving Insert 16ER/IL HG220TR Carbide

Product Description

The HERTEL H82331562 is a solid carbide grooving insert designed for external and internal grooving and turning operations on CNC lathes and turning centers. Built to the 16ER/IL0.062 style, this right-hand insert features a 0.062-inch cutting width and a maximum depth of cut of 0.075 inches. The HG220TR grade substrate carries a TiC and TiN multilayer coating for wear resistance and thermal stability during interrupted and continuous grooving cuts. A 15-degree rake angle and 10-degree external relief angle support clean chip evacuation at typical grooving feeds. Machinists and CNC operators install this insert into compatible 16ER/IL toolholders as a direct replacement or standard production consumable.

This insert is suited for grooving, recessing, and undercutting operations on a variety of workpiece materials including steel, stainless, and alloys. The 3/8-inch inscribed circle and 0.004-inch corner radius make it appropriate for precision groove profiles where tight dimensional tolerances are required. It is used in job shops, production machining cells, and maintenance and repair operations where consistent groove geometry is needed across repeat setups.

Key Features

• Solid carbide substrate with TiC and TiN multilayer coating for wear and heat resistance
• 0.062-inch cutting width for narrow grooving and recessing applications
• Maximum depth of cut of 0.075 inches, with a range up to 0.100 inches
• Right-hand 16ER/IL style fits standard 16ER/IL series toolholders
• 15-degree rake angle and 10-degree external relief angle for positive chip flow
• 0.004-inch corner radius maintains precise groove profile geometry

Compatibility

Designed for use in 16ER/IL style grooving toolholders. Confirm holder bore and insert pocket specifications match the 16ER/IL 16 style and 3/8-inch inscribed circle before installation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the insert clamp to the recommended seating torque for the holder series. Inspect the insert pocket and clamp for wear or debris before each insert change to ensure proper seating and runout control.
