Hertel H82331547 Grooving Insert 0.047 in Solid Carbide

Product Description

The HERTEL H82331547 is a solid carbide grooving insert designed for external and internal grooving operations on CNC lathes and turning centers. Manufactured to the 16ER/IL style, this right-hand insert features a 0.047-inch cutting width and a maximum depth of cut of 0.063 inches. The manufacturer grade is HG220TR, finished with a TiC and TiN multilayer coating that improves wear resistance and extends tool life in ferrous and non-ferrous turning applications. Installation and toolholder selection require matching this insert to a compatible 16ER/IL-style holder with the correct bore and clamping system.

This insert is suited for grooving, undercutting, and recessing operations in precision machining environments. It is commonly used in job shops, production machining facilities, and toolrooms where tight dimensional tolerances are required. The 0.063-inch maximum depth of cut makes it appropriate for shallow groove profiles in bar stock, turned components, and shaft work. The right-hand orientation is standard for most conventional turning setups where the spindle rotates counterclockwise when viewed from the tailstock.

Key Features

• 16ER/IL insert style for compatibility with standard grooving toolholders
• 0.047-inch cutting width for precise groove dimensioning
• 0.063-inch maximum depth of cut for shallow grooving and undercutting
• Solid carbide substrate with TiC and TiN coating for improved wear resistance
• HG220TR manufacturer grade suited for grooving operations in turning applications
• 15-degree rake angle and 10-degree external relief angle for controlled chip formation

Compatibility

Designed for use with 16ER/IL-style grooving toolholders accepting a 3/8-inch inscribed circle insert. Verify holder clamping style and insert pocket geometry before installation.

Installation Notes

This insert is installed by a machinist or toolroom technician following standard carbide insert replacement procedures. Power down and lock out the machine before changing inserts. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the clamping screw to the recommended seating torque for the holder model in use. Inspect the insert pocket and contact surfaces for wear or debris before seating the new insert.
