Ingersoll Cutting Tools 5518014 Turning Insert DNGG432ML K10

Product Description

The INGERSOLL CUTTING TOOLS 5518014 is a solid carbide turning insert in the DNGG series, designed for precision single-point turning operations on CNC and manual lathes. It carries the K10 uncoated carbide grade, making it well-suited for dry or minimally lubricated cutting where coating buildup is a concern. The insert features a 55-degree diamond shape, a 0.5 inch inscribed circle, a 0.031 inch corner radius, and an overall length of 0.61 inches. The ML chip breaker geometry supports light to medium finishing passes. Licensed machinists and CNC operators install this insert in standard DNGG-style toolholders using a clamp-style holding method.

This insert is intended for turning cast iron, non-ferrous metals, and super-alloys including titanium. It is commonly used in production turning environments where consistent surface finish and dimensional accuracy are required across these material groups. The negative rake geometry and four available cutting edges support efficient tool utilization, reducing per-edge cost in high-cycle operations. The insert conforms to ISO standards and carries the ISO designation DNGG150408ML K10, which aids cross-referencing with toolholder and insert selection charts.

Key Features

• Solid carbide K10 uncoated grade suited for cast iron, non-ferrous, and super-alloy turning
• 55-degree diamond insert shape with four cutting edges for extended tool life
• ML chip breaker geometry optimized for light to medium finishing depths of cut
• 0.031 inch corner radius balances surface finish quality with edge strength
• Maximum depth of cut of 0.138 inches supports controlled finishing passes

Compatibility

Designed for use in DNGG-series clamp-style turning toolholders. ANSI code DNGG432MLK10 and ISO code DNGG150408ML K10 can be used to confirm toolholder and insert pocket compatibility using standard selection references.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine before seating or indexing the insert. Use the appropriate torque wrench and manufacturer-specified clamp hardware to secure the insert; do not over-tighten the clamp screw. Inspect the insert pocket and clamp for wear or debris before installation to ensure proper seating and edge repeatability.
