Kennametal 2226032 VNMG331MS K313 Carbide Turning Insert

Product Description

The KENNAMETAL 2226032 is a solid carbide, uncoated turning insert in the VNMG331MS geometry, part of the KENLOC series. It features a 35-degree diamond (rhombic) insert shape with a neutral hand orientation and a negative rake and side clearance configuration. The inscribed circle measures 3/8 inch (0.3750 inch decimal), the insert length is 16.61 mm (0.6537 inches), and the corner radius is 1/64 inch (0.0156 inch). Grade K313 is engineered for high wear-resistance with moderate toughness across stainless steel, cast iron, and non-ferrous and aluminum workpiece materials. The MS chip breaker targets roughing and medium machining operations. Licensed machinists, CNC operators, and tool-and-die professionals are the primary users of this insert.

This insert is suited for turning, facing, boring, back turning, and back boring operations on non-ferrous metals, superalloys, titanium, stainless steel, and cast iron. The VNMG geometry with a negative rake is commonly used on rigid setups where cutting forces and tool life are primary concerns. The 35-degree diamond shape provides access in tight-clearance profiles and contour work. With four available cutting edges, the 2226032 delivers consistent performance across production and job-shop environments running ISO and ANSI-standard toolholders. This insert is sold individually and requires a minimum order of 5 pieces.

Key Features

• Grade K313 uncoated solid carbide with high wear-resistance for stainless steel, cast iron, and non-ferrous materials
• MS chip breaker geometry optimized for roughing and medium machining operations
• 35-degree diamond (rhombic) insert shape for contour turning and profiling in tight-clearance applications
• Four cutting edges per insert for extended tooling economy
• Negative rake and negative side clearance for use in rigid, high-stability setups
• Compatible with clamp and pin insert holding methods
• Conforms to both ANSI (VNMG331) and ISO (VNMG160404) standards

Compatibility

Designed as an OEM-style replacement or direct-fit insert for ANSI VNMG331 and ISO VNMG160404 compatible toolholders accepting clamp or pin retention, per the KENLOC series specification. Specific toolholder compatibility should be confirmed against KENNAMETAL KENLOC toolholder documentation for VNMG-style inserts.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. The machine spindle must be powered down and all motion stopped before indexing or replacing inserts. Seating surfaces on the toolholder pocket should be cleaned of chips and debris before installing a new insert to ensure proper seating and edge engagement. Do not exceed the maximum depth of cut specification for this insert geometry, and verify toolholder clamping torque against the toolholder manufacturer's documentation rather than generic values.
