Hertel H82331521 Grooving Insert 0.031 in Solid Carbide

Product Description

The HERTEL H82331521 is a solid carbide grooving insert designed for precision external and internal grooving and threading operations on CNC lathes and turning centers. Built to the 16ER/IL style standard, this insert features a 0.031-inch cutting width and a maximum depth of cut of 0.055 inches. A dual-layer TiC and TiN coating improves wear resistance and surface finish consistency across a range of workpiece materials. The right-hand orientation suits conventional turning setups, and a 15-degree rake angle contributes to controlled chip formation. Machining professionals and toolroom technicians are the primary installers of this insert type.

This insert is suited for grooving, profiling, and threading operations on small-diameter workpieces where tight tolerances on groove width and depth are required. The 0.004-inch corner radius and a 3/8-inch inscribed circle make it appropriate for fine-pitch groove work. It is applicable to both external and internal operations based on the 16ER/IL insert style designation. Typical use environments include production machining cells, job shops, and tool and die operations working in steel, stainless steel, and similar machinable metals.

Key Features

Compatibility

Designed for use with toolholders accepting the 16ER/IL insert style with a 3/8-inch inscribed circle. Confirm toolholder pocket specifications before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and the turret is de-energized before changing inserts. Verify that the toolholder pocket and clamping surfaces are clean and free of chips or debris prior to seating the insert. Follow the toolholder manufacturer's clamping torque and procedure specifications.
