Hertel H82331653 Grooving Insert 0.062 in Solid Carbide HG220TR

Product Description

The HERTEL H82331653 is a solid carbide grooving insert designed for external threading and grooving operations on CNC lathes and turning centers. Configured in the 16IR/EL style with a right-hand orientation, it carries a 0.062-inch cutting width and a maximum depth of cut of 0.075 inches. The insert is finished with a TiC and TiN multilayer coating under the HG220TR grade designation, providing wear resistance suited to steel and general-purpose turning materials. Machinists and CNC operators working in production or job-shop environments install this insert as a direct replacement unit in compatible 16IR/EL toolholders.

This insert is intended for external grooving and threading applications on manual and CNC lathes. The right-hand cutting orientation suits the standard front-to-back feed direction common in most turning setups. With a 3/8-inch inscribed circle, it fits toolholders in the 16IR/EL family. The 15-degree rake angle and 10-degree external relief angle support clean chip evacuation in groove profiling work. Typical applications include snap-ring grooves, undercuts, and form-relief grooves on turned components. This is a single-insert package sold in minimum order quantities of 10 units.

Key Features

• Solid carbide substrate for rigidity and long edge life in interrupted and continuous cuts
• TiC and TiN multilayer coating under HG220TR grade for improved wear resistance
• 0.062-inch cutting width with a maximum depth of cut of 0.075 inches
• 15-degree rake angle and 10-degree external relief angle for controlled chip flow
• 0.004-inch corner radius for defined groove shoulder geometry
• Right-hand orientation for standard lathe turning direction

Compatibility

Designed for use in 16IR/EL-style grooving toolholders with a 3/8-inch inscribed circle seat. Confirm toolholder manufacturer specifications before installation to verify insert pocket geometry and clamping compatibility.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Use the correct torque wrench or insert key specified by the toolholder manufacturer when securing the clamping screw — do not over-tighten by hand. Inspect the insert pocket and clamping surfaces for chips or debris before seating the new insert, as contamination affects runout and edge life.
