Kennametal 7093270 Vngg Carbide Turning Insert VNGG3302

Product Description

The KENNAMETAL 7093270 is a VNGG-style indexable carbide turning insert designed for finishing operations on CNC and manual turning centers. It carries grade KCU10B with an AlTiN coating, delivering high wear resistance across steel, stainless steel, cast iron, aluminum, and non-ferrous workpiece materials. The insert follows ANSI code VNGG3302 and ISO code VNGG160401. The V-diamond (rhombic) 35-degree included angle geometry provides a tight nose radius of 0.0040 inches, making it well suited for light finishing passes where surface finish and dimensional accuracy are the priority. The neutral hand orientation allows use in both left- and right-hand toolholders. Licensed machinists and CNC operators install this insert on production and job-shop turning equipment.

This insert is used in finishing applications on steel (P), stainless steel (M), cast iron (K), aluminum, and non-ferrous (N) workpiece materials, as well as heat-resistant superalloys (S). The 35-degree point angle and 0.0040-inch corner radius make it appropriate for profiling, contouring, and fine-pass turning where minimal radial cutting force and a clean surface finish are required. The four available cutting edges on the neutral-hand, negative-clearance geometry help reduce per-edge tooling cost in high-volume turning operations.

Key Features

• ANSI insert code VNGG3302, ISO insert code VNGG160401 for direct toolholder cross-reference
• Grade KCU10B with AlTiN coating for high wear resistance on steel, stainless, and cast iron
• 35-degree V-diamond (rhombic) insert shape with 0.0040-inch corner radius optimized for finishing cuts
• Four cutting edges per insert with neutral hand and negative side clearance (clearance code N)
• FS chip breaker geometry tuned for finishing operations
• Carbide substrate with 0.375-inch inscribed circle and 0.1875-inch thickness

Compatibility

Designed as an OEM-style replacement or direct-fit insert for VNGG-style turning toolholders accepting ANSI size code 3302 inserts with negative clearance geometry.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer — do not overtighten, as carbide inserts are brittle and can fracture under excessive clamp force. Inspect the toolholder pocket and clamping hardware for wear or debris before seating a new insert.
