Hertel H82331620 Grooving Insert HG220TR Solid Carbide

Product Description

The HERTEL H82331620 is a solid carbide grooving insert designed for external threading and grooving operations on CNC lathes and turning centers. It carries the 16IR/EL insert style designation and is finished with a TiC and TiN coating for improved wear resistance and heat dissipation during interrupted cuts and continuous grooving passes. The insert delivers a 0.039 inch cutting width with a maximum depth of cut of 0.055 inches and a corner radius of 0.004 inches. Right-hand orientation positions it for standard lathe setups. Machinists and toolroom technicians working with steel and alloy materials will find this insert suited to precision grooving, undercutting, and parting applications.

This insert is intended for use in external grooving and turning applications on manual and CNC lathes. The 16IR/EL style and 3/8 inch inscribed circle sizing make it compatible with toolholders designed for that insert family. The HG220TR grade targets general-purpose grooving where a TiC/TiN coated solid carbide substrate is appropriate. Typical install scenarios include precision part production in job shops, production turning cells, and maintenance machining environments. The insert is sold individually but carries a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate with TiC and TiN multilayer coating for extended tool life
• 0.039 inch cutting width for narrow groove and undercut profiles
• Maximum depth of cut of 0.055 inches within a range of 0.000 to 0.075 inches
• Right-hand cutting orientation for standard external grooving setups
• 15-degree rake angle and 10-degree external relief angle for positive chip clearance
• 0.004 inch corner radius for defined groove edge geometry

Compatibility

Designed as a direct-fit replacement for 16IR/EL style insert seats with a 3/8 inch inscribed circle; verify toolholder pocket specifications before installation.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to secure the insert without over-torquing the clamping mechanism. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert.
