Kennametal 1162234 Turning Insert VBMT331LF K313 Carbide

Product Description

The KENNAMETAL 1162234 is a solid carbide, uncoated turning insert in the VBMT style, designed for precision metal removal on CNC lathes and turning centers. Manufactured to grade K313 with a bright, uncoated finish, this insert carries a 35-degree diamond (V) shape with a positive rake angle of 5 degrees and a relief angle of 5 degrees. The inscribed circle measures 3/8 inches, insert length is approximately 16.61 mm (0.651 inches), and the corner radius is 1/64 inch (0.0156 inches). The LF chip breaker geometry is optimized for light finishing cuts. Installed via screw-on holding method, this insert is suited for machinists and CNC operators working in production turning environments.

This insert is intended for use on non-ferrous metals, superalloys, and titanium workpieces, corresponding to ISO work material codes N and S. Typical applications include turning, facing, boring, back turning, and back boring operations. The honed cutting edge style delivers a consistent finish on these demanding materials. It is commonly used in horizontal and vertical turning centers where repeatable insert indexing and secure screw-on clamping are required. The VBMT format is a widely adopted industry-standard insert geometry, making this insert a practical choice for shops running mixed-material production schedules.

Compatibility

Designed as an OEM-style screw-on replacement insert compatible with VBMT-style toolholders conforming to ANSI and ISO standards for 3/8-inch inscribed circle, screw-on inserts with a 0.1732-inch (4.40 mm) hole diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Shut down and lock out the machine before changing inserts. Use the correct Torx or hex key specified by the toolholder manufacturer to seat the clamping screw; do not overtighten. Inspect the insert pocket and seating surface for chips or damage before indexing to a fresh cutting edge.
