Kennametal 1113044 Grooving Insert NG2125 KC730 Carbide

Product Description

The KENNAMETAL 1113044 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured to the NG2125 insert style in the Top Notch series, it carries a PVD-applied TiN coating and a KC730 grade designation, placing it in the C2, C3, and C4 material grades. The insert is configured for left-hand cutting with a neutral rake geometry, a 3.18 mm cutting width, and a maximum depth of cut of 2.79 mm. Machinists and CNC lathe operators working in production and job-shop environments rely on this insert for consistent, repeatable groove profiles.

This insert is suited for grooving applications in general metalworking environments where carbide tooling is specified for steel, stainless, and cast-iron workpiece materials. The Top Notch series tooling system is a common platform in both manual and CNC turning applications. The 55-degree included angle and a 0.19 mm corner radius support clean entry and controlled chip formation in shallow-to-medium depth grooving scenarios within the 2.00 mm to 3.00 mm depth-of-cut range. It is intended for use in compatible Top Notch series toolholders designed to accept NG-style inserts.

Compatibility

Designed for use with Top Notch series toolholders that accept NG-style grooving inserts. Consult toolholder specifications to confirm shank size and insert pocket compatibility before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician following the toolholder manufacturer's clamping torque guidelines. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Do not exceed the recommended depth-of-cut range for this insert style.
