Value Collection ICP17770M TNMG332 Carbide Turning Insert

Product Description

The VALUE COLLECTION ICP17770M is a solid carbide turning insert designed for precision metal cutting on CNC lathes and manual turning centers. Manufactured to ANSI Insert Code TNMG332 and ISO Insert Code TNMG160408, this insert features an Al2O3 (aluminum oxide) ceramic coating that improves wear resistance and thermal stability during continuous and interrupted cuts. The triangular shape provides three usable cutting edges, reducing tooling cost per edge. With a 3/8-inch inscribed circle and a 1/32-inch corner radius, it is suited for medium-depth finishing and semi-finishing passes. Licensed machinists and CNC operators are the primary users of this consumable tooling item.

This insert is designed for turning applications on cast iron (ISO material group K) and non-ferrous materials (ISO material group N), consistent with the K and N primary workpiece material codes. It fits TNMG-style toolholders with clamp-and-pin holding methods and a negative side clearance geometry. Typical applications include OD turning, facing, and profiling operations in production and job-shop environments where consistent surface finish and dimensional accuracy are required.

Key Features

• ANSI Insert Code TNMG332 / ISO Insert Code TNMG160408 for broad toolholder compatibility
• Al2O3 ceramic coating provides elevated hardness and oxidation resistance at high cutting temperatures
• Triangular shape (60-degree included angle) delivers three cutting edges per insert
• 1/32-inch corner radius suitable for semi-finishing and finishing cuts
• Negative side clearance geometry with clamp-and-pin holding for secure seating
• Material grade C2 carbide substrate for balanced toughness and hardness

Compatibility

Designed as a replacement-grade insert for TNMG-style negative-rake turning toolholders that accept a TNMG332 (ISO TNMG160408) insert with a 0.1500-inch hole diameter and clamp-and-pin retention.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before indexing or replacing inserts, de-energize the machine, engage the spindle lock, and follow lockout/tagout procedures. Use the appropriate torx or hex key to release the clamp and seat the new insert fully against the toolholder pocket before re-torquing the clamp. Inspect the toolholder pocket and shim for wear or debris before seating each new insert.
