Kennametal 1113085 Grooving Insert NG4213 KC730 Carbide Tin

Product Description

The KENNAMETAL 1113085 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. It carries a KC730 grade designation with a PVD-applied TiN coating, which improves wear resistance and edge life on a range of workpiece materials. The insert has a right-hand orientation, a cutting width of 5.41 mm (0.213 inches), and a maximum depth of cut of 6.35 mm (0.250 inches). The neutral rake geometry and 0.19 mm corner radius support consistent chip control in light to moderate grooving passes. Machinists and CNC operators install this insert in compatible Top Notch toolholders.

This insert is suited for production grooving on materials falling within the C2, C3, and C4 material grade classifications, covering a range of cast irons, non-ferrous metals, and harder workpiece materials. The Top Notch series is a common platform in job shops and production environments running medium-duty grooving cycles. The NG4213R seat configuration fits standard Top Notch insert pockets at seat size 4. It is appropriate for both manual and automated CNC turning operations where consistent groove geometry is required.

Key Features

• Solid carbide substrate with PVD TiN coating for extended edge wear resistance
• Cutting width of 5.41 mm (0.213 inches) for precise groove sizing
• Maximum depth of cut of 6.35 mm (0.250 inches), with an effective range of 5.00 mm to 10.00 mm
• Right-hand orientation with neutral rake for controlled chip formation
• Corner radius of 0.19 mm (0.0075 inches) supports clean groove floor geometry
• Top Notch series platform for broad toolholder compatibility

Compatibility

Designed for use in Top Notch series toolholders accepting a size 4 insert seat. The insert seat designation is NG4213R. Verify toolholder pocket specifications before installation to confirm proper seating and clamping.

Installation Notes

Grooving inserts of this type are installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamp screw specified for the toolholder to avoid cracking the carbide substrate — do not over-tighten by hand estimation. Inspect the insert seat and clamping mechanism for chips or debris before seating the new insert.
