Kennametal 1113404 NG3062 K420 Grooving Insert Carbide

Product Description

The KENNAMETAL 1113404 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. Manufactured in grade K420 with a bright uncoated finish, this insert delivers a 1.58 mm cutting width and a maximum depth of cut of 2.39 mm. The neutral rake geometry and 55-degree included angle provide stable, controlled chip flow during grooving passes. Right-hand orientation, insert size 3062, and an NG style make this a direct-fit replacement for compatible Top Notch toolholders. Machinists and CNC turning specialists install and index these inserts during routine tooling changeovers.

This insert is suited for precision grooving applications in metalworking environments, including job shops and production turning operations. The K420 carbide grade is formulated for use on cast iron and nonferrous materials where a sharp, uncoated edge is preferred. The 0.19 mm corner radius (0.0075 inches) and neutral rake angle support consistent groove geometry on parts requiring tight tolerances. It is compatible with Top Notch series NG-style grooving toolholders used on manual and CNC lathes. Minimum order quantity is 5 inserts; each package contains 1 insert.

Installation Notes

Indexable grooving inserts should be installed and indexed by a qualified machinist or CNC tooling technician. Always 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 seating the insert. Do not exceed the rated maximum depth of cut for the insert size in use.
