Ingersoll Cutting Tools 5515734 Turning Insert CNMG431MP

Product Description

The INGERSOLL CUTTING TOOLS 5515734 is a solid carbide turning insert designated CNMG431MP in the TT8020 grade. It features a Physical Vapor Deposition (PVD) TiCN coating applied over a carbide substrate, delivering wear resistance and edge toughness in demanding turning operations. The insert has a diamond (80-degree) shape, a neutral hand orientation, a 0.5 inch inscribed circle, and a 1/64 inch (0.016 inch) corner radius. With four cutting edges and a negative rake geometry, it is suited for indexable turning toolholders used by machinists and CNC lathe operators in production and job-shop environments.

This insert is designed for turning stainless steel, carbon and alloy steel, superalloys, and titanium - workpiece material codes M, P, and S under ISO classification. The MP chip breaker geometry handles medium-depth passes with a maximum depth of cut of 0.157 inch, making it appropriate for semi-finishing and moderate roughing operations on CNC and manual lathes. It is clamped in place using a top-clamp or lever-lock toolholder system compatible with the CNMG pocket standard.

Key Features

• TT8020 grade with PVD TiCN coating for toughness and wear resistance in stainless steel and superalloy turning
• 80-degree diamond insert shape (CNMG style) provides strong cutting edge geometry with a neutral hand
• MP chip breaker optimized for semi-finishing to moderate roughing cuts
• Four usable cutting edges per insert reduce cost per edge
• Negative rake, zero-degree relief angle (clearance code N, tolerance code M) for rigid, stable cutting action
• ISO-standard geometry (ISO code CNMG120404MP TT8020) for broad toolholder compatibility

Compatibility

Designed for use in CNMG-style indexable turning toolholders with a clamp-style insert holding method. Compatible with ISO CNMG insert pockets. Primary workpiece materials are stainless steel (M), carbon and alloy steel (P), superalloys and titanium (S) per ISO material classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench for the clamp screw to avoid cracking the insert or damaging the pocket seat - refer to the toolholder manufacturer specifications for torque values. Inspect the pocket seat and clamp for wear or debris before seating a new insert.
