Kennametal 1113266 Grooving Insert NG3062 K313 Carbide

Product Description

The KENNAMETAL 1113266 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the Top Notch series standard with an NG insert style, this insert delivers a 1.58 mm (0.0622 inch) cutting width and a maximum depth of cut of 2.39 mm (0.0941 inch). The K313 grade is an uncoated, bright-finish carbide formulation suitable for C3 and C4 material grades. Configured for left-hand cutting with a neutral rake and a 55-degree included angle, it suits applications where consistent groove geometry and dimensional accuracy are required. Machinists and CNC turning specialists are the primary installers.

This insert is intended for use in turning and grooving operations across a range of workpiece materials aligned with C3 and C4 carbide grade classifications, which typically cover cast iron and non-ferrous materials. The Top Notch series platform is a widely used system in production turning environments, making this insert appropriate for both job-shop and high-volume manufacturing settings. The left-hand orientation suits toolholders and turrets configured for that cutting direction. A corner radius of 0.19 mm (0.0075 inch) supports clean groove floor geometry while the 3-degree lead angle aids chip control at the cutting edge.

Key Features

• Solid carbide construction, uncoated bright finish — no coating delamination risk in abrasive or interrupted cuts
• 1.58 mm cutting width with a maximum depth of cut range of 2.00 to 3.00 mm for precise groove sizing
• Left-hand cut orientation for compatibility with LH-configured Top Notch toolholders
• 0.19 mm corner radius for accurate groove floor geometry
• Neutral rake geometry promotes stable cutting forces across compatible workpiece materials
• NG insert style in size 3062 for direct drop-in fitment in Top Notch series holders

Compatibility

Designed for use with Top Notch series grooving toolholders that accept the NG3062 insert style in a left-hand configuration.

Installation Notes

Installation is performed by CNC machinists or turning center operators. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torx or clamping key specified for the Top Notch holder to secure the insert without overtightening the clamping screw. Inspect the insert pocket and clamping components for chips or wear before seating a new insert to ensure proper seating and accurate cutting geometry.
