Kennametal 1161360 Turning Insert VNGP432 KC850 Carbide

Product Description

The KENNAMETAL 1161360 is a solid carbide turning insert in the VNGP432 geometry, designed for precision metal cutting operations in CNC lathes and turning centers. It features a multilayer CVD coating of TiC, TiCN, and TiN under the KC850 manufacturer grade, which balances moderate wear resistance with toughness across a wide range of workpiece materials. The insert carries a 35-degree diamond (rhombic) shape, a 0.5-inch inscribed circle, and a 1/32-inch corner radius. It is suited for steel and stainless steel as primary workpiece materials, with cast iron and special or super alloys as secondary applications. Licensed machinists and CNC turning specialists are the primary installers of this insert.

This insert belongs to the KENNAMETAL KENLOC series and is rated for medium machining chip breaker operation. The VNGP style with neutral hand makes it adaptable across multiple cutting directions. Typical applications include turning, facing, boring, back turning, and back boring. The negative rake and negative side clearance geometry are standard for heavy-duty cutting conditions where edge stability under load is a priority. The KC850 grade is specifically characterized for steel (P), stainless steel (M), cast iron (K), and special and super alloys (S), covering the most common material codes encountered in production machining environments.

Key Features

• VNGP432 geometry with 35-degree diamond insert shape for controlled cutting engagement
• KC850 grade with multilayer CVD coating: TiC, TiCN, and TiN for wear resistance and toughness
• Neutral hand insert supports turning, facing, boring, back turning, and back boring
• 4 cutting edges per insert maximize tool life and reduce per-edge cost
• Honed cutting edge style provides consistent edge preparation for stable cuts
• Compatible with clamp and pin insert holding methods for flexible toolholder pairing
• Meets ANSI and ISO standards; ANSI code VNGP432, ISO code VNGP220408

Compatibility

Designed for use in KENNAMETAL KENLOC series toolholders that accept VNGP-style inserts with clamp or pin holding. Verified compatible insert holding methods are clamp and pin. Confirm toolholder pocket geometry and clamping system match VNGP432 specifications before installation.

Installation Notes

Insert replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped, spindle locked, and all energy sources isolated per applicable lockout/tagout procedures. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer; do not overtighten the clamp screw. Inspect the toolholder pocket for wear or debris before seating the new insert. Index to an unused cutting edge before replacing the insert entirely to maximize the value of all 4 available edges.
