Kennametal 1114648 NG3062K K68 Grooving Insert Top Notch

Product Description

The KENNAMETAL 1114648 is a solid carbide, uncoated grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the NG3062K geometry with a Kennametal K68 grade, this insert delivers a 1.58 mm cutting width and a maximum depth of cut of 2.39 mm. The positive rake angle of 10 degrees and the K chip breaker geometry promote controlled chip formation and reduced cutting forces. It is intended for right-hand cutting orientation. Machinists and CNC operators install this insert into compatible Top Notch toolholders for high-repeatability grooving applications.

This insert is suited for grooving, recessing, and light parting operations on a variety of workpiece materials. The K68 carbide grade and bright uncoated finish make it particularly well matched to non-ferrous and cast iron machining applications where coating is not required or desired. The 55-degree included angle and 0.19 mm corner radius support fine-detail groove profiles. It is used in both production shop and job shop environments on manual and CNC turning equipment.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before seating or replacing inserts. Use the correct torx or clamp-style wrench specified for the Top Notch toolholder to secure the insert without over-torquing the clamp screw. Verify insert seating and runout before resuming cutting operations.
