Kennametal 1162233 Turning Insert VBMT330.5LF K313 Carbide

Product Description

The KENNAMETAL 1162233 is a solid carbide, uncoated turning insert carrying the ANSI designation VBMT3305LF and ISO designation VBMT160402. It is a 35-degree diamond (rhombic) shape insert in the K313 grade, designed for finishing and light machining operations on CNC lathes and turning centers. The insert measures 16.61 mm in length with a 0.375 inch inscribed circle, a 0.1875 inch thickness, and a 0.0079 inch corner radius. It mounts via screw-on holding method with a positive rake and positive side clearance. Licensed machinists and CNC turning specialists install this insert in screw-on toolholders for precision finish passes.

This insert is suited for turning, facing, boring, back turning, and back boring operations. Its K313 grade targets stainless steel (M-class), cast iron (K-class), aluminum and non-ferrous metals (N-class), as well as superalloys and titanium (S-class), delivering high to moderate wear resistance with balanced toughness. The LF chip breaker geometry is optimized for finishing and light machining, making this insert appropriate for tight-tolerance finish passes in both job shop and production turning environments. It conforms to ANSI and ISO insert standards.

• Conforms to ANSI (VBMT3305) and ISO (VBMT160402) standards

Compatibility

Designed as an OEM-style replacement or direct application insert for screw-on VBMT-style toolholders accepting a 3/8 inch inscribed circle, 35-degree diamond insert per ANSI VBMT3305 and ISO VBMT160402 specifications.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before changing inserts, ensure the machine spindle is fully stopped and locked out per shop lockout/tagout procedures. Use the appropriate Torx or hex key as specified by the toolholder manufacturer to secure the clamp screw to the correct seating torque. Inspect the toolholder pocket and seating surfaces for chips or debris before installing the new insert to ensure proper seating and edge geometry.
