Hertel H82331661 Grooving Insert 0.067 in Solid Carbide

Product Description

The HERTEL H82331661 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to insert style 16IR/EL, this right-hand insert delivers a cutting width of 0.067 inches and a maximum depth of cut of 0.079 inches. The TiC and TiN multilayer coating over the solid carbide substrate improves wear resistance and extends tool life across ferrous and non-ferrous materials. Machinists and CNC operators working in production and job-shop environments rely on this insert for consistent groove geometry and edge integrity on tight-tolerance workpieces.

This insert is suited for external and internal grooving applications where controlled width and depth are critical. Its HG220TR grade and 15-degree rake angle are appropriate for medium to light-cut finishing operations in production turning. The 0.004-inch corner radius produces a near-sharp edge profile suitable for close-tolerance grooves. It fits toolholders accepting the 16IR/EL insert style with a 3/8-inch inscribed circle seating geometry, making it compatible with a range of standard indexable grooving toolholders used in the machining trade.

Key Features

• Solid carbide substrate with TiC and TiN multilayer coating for extended wear resistance
• 0.067 inch cutting width for precise groove sizing
• Maximum depth of cut of 0.079 inches, with a rated range of 0.075 to 0.100 inches
• Right-hand orientation with a 15-degree rake angle and 10-degree external relief angle
• 0.004 inch corner radius for near-sharp edge profile
• 3/8-inch inscribed circle for compatibility with standard 16IR/EL toolholders

Compatibility

Designed for use with indexable grooving toolholders that accept the 16IR/EL insert style with a 3/8-inch inscribed circle seating geometry. Consult toolholder manufacturer documentation to confirm insert pocket fit before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before seating the insert. Use a calibrated torque wrench and the clamping screw specified by the toolholder manufacturer to avoid over-torquing the insert pocket. Inspect the insert seat and clamp for debris or damage before each insert change. Confirm cutting direction and toolholder orientation match the right-hand designation before starting a cut.
