Value Collection ICC18260L TNMG666 Turning Insert Carbide

Product Description

The VALUE COLLECTION ICC18260L is a solid carbide, uncoated turning insert in TNMG666 style, designed for external and internal turning operations on CNC lathes and manual turning centers. Manufactured to ANSI insert code TNMG666 and ISO insert code TNMG330924, this insert features a 3/4-inch inscribed circle, a 3/32-inch corner radius, and a 60-degree triangular geometry with a negative side clearance. Grade I55 solid carbide construction provides rigidity and wear resistance in demanding metal-cutting applications. The chip breaker code G promotes controlled chip formation during turning passes. This insert is installed by machinists and toolroom technicians working in production or maintenance machining environments.

This insert is suited for turning operations on ferrous workpiece materials, consistent with primary workpiece material code P, which covers steel and cast iron. Material grades C5 and C6 indicate applicability for general-purpose turning and finishing passes on steel alloys. The TNMG style with negative rake and a clamp-and-pin holding method makes it appropriate for moderate to heavy interrupted and continuous cuts. Typical applications include shaft turning, facing, and contour work on standard CNC turning centers using TNMG-compatible toolholders.

Key Features

• Solid carbide, bright/uncoated finish for sharp cutting edge retention
• ANSI insert code TNMG666, ISO code TNMG330924 for broad toolholder compatibility
• 60-degree triangular insert shape with negative side clearance for rigidity
• 3/32-inch corner radius (0.0938 inches) for controlled surface finish
• Grade I55 carbide with G chip breaker geometry for controlled chip evacuation
• Clamp and pin holding method for secure seating in TNMG toolholders

Compatibility

Designed as an OEM-style replacement or direct-fit insert for TNMG-style toolholders accepting a 666 size code insert with a 0.315-inch hole diameter and clamp-and-pin retention.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer to secure the insert. Inspect the insert pocket and seating surface for chips or damage before seating a new insert.
