Kennametal 1114490 Grooving Insert NGD3094K K313 Carbide

Product Description

The KENNAMETAL 1114490 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Manufactured to the NGD3094K insert style in Kennametal grade K313, this uncoated bright-finish insert features a 2.39 mm cutting width and a maximum depth of cut of 6.35 mm. The positive 10-degree rake angle and left-hand orientation make it suited for specific tool holders within the Top Notch series. The solid carbide substrate without coating delivers consistent edge integrity on harder workpiece materials where an uncoated grade performs best.

This insert is intended for grooving and parting applications in metalworking environments, typically on CNC turning equipment operated by machining professionals. It fits within the Top Notch grooving system and is appropriate for applications where a left-hand insert geometry is required. The K313 grade, rated for C3 and C4 material grades, is well suited for cutting harder non-ferrous and cast materials. The 0.19 mm corner radius and 55-degree included angle support controlled chip formation in tight-tolerance groove profiles.

Key Features

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Use the appropriate Torx or hex key for the Top Notch toolholder clamping screw and confirm the insert seats fully and securely before resuming cuts. Do not exceed the rated maximum depth of cut for this insert style.
