Kennametal 1113064 Grooving Insert NG3088 KC730 Carbide

Product Description

The KENNAMETAL 1113064 is a solid carbide grooving insert in the Top Notch series, designed for precision external grooving and parting operations on CNC lathes and turning centers. It carries a TiN coating applied via PVD process, which improves surface hardness and wear resistance without significantly altering edge geometry. The insert features a 2.24 mm cutting width and a maximum depth of cut of 2.39 mm, with a right-hand orientation and neutral rake angle. It suits machinists and toolroom operators working to tight dimensional tolerances on turned components.

This insert is suited for grooving operations on materials falling within C1, C2, C6, and C7 material grades, covering a range of carbon steels, alloy steels, cast irons, and nonferrous materials. It fits production turning environments where consistent groove width and controlled chip evacuation are required. The Top Notch series is a standard toolholding platform used widely in job shops and high-volume turning cells. The 0.19 mm corner radius and 55-degree included angle contribute to stable cutting action in shallow to mid-depth grooves.

Key Features

• Solid carbide substrate with KC730 manufacturer grade for wear resistance in interrupted and continuous cuts
• TiN coating via PVD process for improved surface hardness and edge retention
• 2.24 mm cutting width with a maximum depth of cut of 2.39 mm
• Right-hand insert orientation with neutral rake for balanced cutting forces
• 0.19 mm corner radius reduces stress concentration at groove walls
• Top Notch series platform for broad toolholder compatibility

Compatibility

Designed for use with Top Notch series toolholders accepting NG-style inserts, insert size 3088. MSC and manufacturer cross-reference number is NG3088R/L. Compatible with C1, C2, C6, and C7 material grade workpieces.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before inserting. Follow the toolholder manufacturer torque guidelines for the clamping screw to avoid cracking the carbide substrate.
