Kennametal 1113093 Grooving Insert KC730 Carbide Tin Rh

Product Description

The KENNAMETAL 1113093 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries a KC730 grade designation with a PVD-applied TiN coating, delivering wear resistance and edge integrity on a range of workpiece materials including carbon steels, alloy steels, and cast iron per material grades C2, C3, and C4. The insert features a right-hand orientation, a cutting width of 0.125 inches (3.18 mm), and a maximum depth of cut of 0.150 inches (3.81 mm). The neutral rake geometry and 0.0075-inch corner radius support controlled chip formation in moderate to finish grooving passes.

This insert is suited for use in production turning environments where repeatable groove width and depth tolerances are required. It fits the Top Notch toolholder system, a common platform in shops running high-volume OD grooving, face grooving, and parting operations on steel and cast iron components. The 55-degree included angle and 3-degree lead angle make it appropriate for standard groove profiles. It is installed and indexed by machinists and CNC lathe operators working in job shop and production environments.

Key Features

• Cutting width of 0.125 inches (3.18 mm) for consistent, repeatable groove dimensions
• Maximum depth of cut of 0.150 inches (3.81 mm); depth range up to 0.200 inches (4.00 mm) depending on application
• Neutral rake geometry with 0.0075-inch (0.19 mm) corner radius for controlled chip flow
• Right-hand insert orientation for standard OD grooving setups
• Top Notch series compatibility for use with existing Top Notch toolholders

Compatibility

Designed for use with Top Notch series toolholders accepting NF-style inserts (manufacturer reference NF3125R/L). Compatible with material grades C2, C3, and C4 workpiece materials.

Installation Notes

Installation and indexing should be performed by a qualified machinist or CNC lathe operator. Ensure the machine spindle is fully stopped and the turret is locked before seating or replacing the insert. Use the appropriate Top Notch clamping hardware and torque the clamp screw to the toolholder manufacturer specification. Inspect the insert seat and clamping surfaces for chips or debris before each index to maintain positional accuracy.
