Ingersoll Cutting Tools 5518013 Turning Insert DNGG431ML K10

Product Description

The INGERSOLL CUTTING TOOLS 5518013 is a solid carbide, uncoated turning insert in the DNGG series, designed for precision single-point turning operations on CNC and manual lathes. It features a 55-degree diamond insert shape with a neutral hand orientation and a K10 carbide grade, making it well-suited for finishing and semi-finishing passes where edge sharpness and wear resistance are critical. The insert measures 0.61 inches in length with a 0.5 inch inscribed circle and a 0.0156 inch corner radius. Holding is achieved via clamp-style toolholders. This insert is specified to ISO standards and carries the ANSI code DNGG431MLK10 and ISO code DNGG150404ML K10.

This insert is intended for turning cast iron, non-ferrous metals, and super-alloys including titanium. The ML chip breaker geometry is optimized for light to medium depth cuts, with a maximum depth of cut of 0.138 inches. It is typically installed by machinists and toolroom professionals in production turning, job-shop, and maintenance machining environments where consistent surface finish and dimensional accuracy are required.
