Kennametal 2244947 Turning Insert VNMG3305MS KC5025 Carbide

Product Description

The KENNAMETAL 2244947 is a VNMG3305MS turning insert in the KC5025 grade, designed for external and internal turning operations in CNC and manual lathe applications. Manufactured from solid carbide with a PVD-applied TiAlN coating, this insert provides moderate wear resistance and toughness across a range of workpiece materials. The insert features a 35-degree diamond (rhombic) shape, a neutral hand orientation, and a honed cutting edge. The 0.0079-inch corner radius and negative rake angle make it well suited for medium machining and roughing passes. It is held using either a clamp or pin method and offers four usable cutting edges per insert, maximizing value per unit in production environments.

This insert is intended for turning, facing, boring, back turning, and back boring operations. The MS chip breaker geometry targets stainless steel and superalloys as primary workpiece materials, with additional suitability for steel, cast iron, aluminum, and non-ferrous materials. The KC5025 grade is engineered for moderate wear resistance and toughness, making it a practical choice for interrupted cuts and variable feed conditions common in job-shop and production machining. Licensed machinists and CNC programmers specifying inserts for stainless steel and titanium alloy components will find this insert aligned to those application demands. The KENLOC series toolholding system provides secure, repeatable clamping with minimal setup time.

Key Features

• VNMG3305MS geometry with 35-degree diamond insert shape and negative rake angle
• KC5025 carbide grade with PVD TiAlN coating for moderate wear resistance and toughness
• Four cutting edges per insert for extended tool life across production runs
• MS chip breaker supports roughing and medium machining operations
• Compatible with clamp and pin holding methods in KENLOC-style toolholders
• Meets ANSI and ISO insert standards (ANSI: VNMG3305, ISO: VNMG160402)

Compatibility

Designed for use in KENLOC series toolholders that accept VNMG-style inserts with a 0.15-inch hole diameter and clamp or pin holding. Suitable for multi-use applications including turning, facing, boring, back turning, and back boring across steel, stainless steel, cast iron, aluminum and non-ferrous materials, and superalloys and titanium.

Installation Notes

Insert replacement should be performed with the machine at a full stop and the spindle locked. Use the appropriate torque wrench and seating tool recommended for the KENLOC clamping system to avoid insert cracking or improper seating. Inspect the insert pocket and clamping pin for wear or debris before seating a new insert. Verify cutting edge orientation and chip breaker position before resuming cutting operations.
