Kennametal 1114703 NG208 K68 Grooving Insert Solid Carbide

Product Description

The KENNAMETAL 1114703 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. Built to the NG insert style in size 208, it features a 0.89 mm cutting width and a maximum depth of cut of 1.27 mm. The uncoated K68 carbide grade delivers a bright finish suited for non-ferrous materials and applications where a sharp, uncoated edge is preferred. The neutral rake geometry and right-hand orientation suit standard radial grooving setups. Machinists and toolroom technicians install this insert as a direct component in Top Notch-compatible toolholders.

This insert is intended for grooving applications on turned components in both production and job-shop environments. Its 0.09 mm corner radius and 1.27 mm maximum depth of cut make it well suited for narrow groove profiles on small-diameter workpieces. The K68 grade is rated as a C3 material grade, making it a practical choice for cutting non-ferrous metals, plastics, and similar materials where carbide wear resistance and edge sharpness are critical. It is sold individually but subject to a minimum order quantity of 5 units.
