Ingersoll Cutting Tools 5519351 Turning Insert CNGG430.5ML

Product Description

The INGERSOLL CUTTING TOOLS 5519351 is a solid carbide uncoated turning insert in the CNGG series, designed for precision metal turning operations on CNC and manual lathes. This neutral-hand insert features an 80-degree diamond shape with a 0.5 inch inscribed circle and a 0.008 inch corner radius, providing four usable cutting edges per insert. The K10 uncoated solid carbide grade delivers consistent performance in applications requiring sharp, clean cutting action. The ML chip breaker geometry is optimized for controlled chip flow and surface finish. Licensed machinists and CNC tooling technicians are the primary installers of this insert type.

This insert is suited for turning cast iron, non-ferrous metals, and super-alloys including titanium. Its negative rake geometry and CNGG-style clamp-held mounting make it appropriate for medium to light finishing cuts. The maximum depth of cut is 0.047 inches, making it best suited for finishing and semi-finishing passes rather than heavy roughing. It is commonly used in production turning cells and job shop environments where consistent dimensional accuracy is required across those workpiece material families.

Key Features

• 80-degree diamond insert shape with 0.5 inch inscribed circle for stable, rigid cutting geometry
• Solid carbide K10 grade, uncoated - suited for cast iron, non-ferrous metals, super-alloys, and titanium
• ML chip breaker geometry for controlled chip formation in light to medium finishing cuts
• Four cutting edges per insert for extended tool life and cost efficiency per edge
• Neutral hand orientation for flexible toolholder compatibility
• Clamp-held insert style with negative rake for secure seating under cutting loads

Compatibility

Designed for use in CNGG-series toolholders with a clamp-style insert holding method. ANSI code CNGG430.5MLK10 and ISO code CNGG120402ML K10 identify compatible toolholder pocket dimensions per ISO standards.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine fully powered down and the spindle locked. Use the appropriate torquing tool for the clamping screw as specified by the toolholder manufacturer. Inspect the insert pocket and shim seat for debris or damage before seating the insert. Never attempt to index or replace an insert while the machine is running or in cycle.
