Ingersoll Cutting Tools 5523642 Cnma Turning Insert TT7015

Product Description

The INGERSOLL CUTTING TOOLS 5523642 is a CNMA-style solid carbide turning insert designed for high-productivity single-point turning operations on cast iron workpieces. It carries the manufacturer grade TT7015 and a three-layer CVD coating stack of TiN, TiCN, and Al2O3, which provides wear resistance and thermal barrier protection across a range of cutting speeds. The diamond insert shape with an 80-degree included angle and a 0.016 inch corner radius delivers a balance of strength and moderate point geometry. Four usable cutting edges reduce per-edge tooling cost in production environments. Licensed machinists and CNC lathe operators working in job shop or production turning applications are the primary users of this insert.

This insert is engineered for turning cast iron, aligning with primary workpiece material code K. The CNMA geometry uses a negative rake angle and a neutral hand orientation, making it adaptable to standard clamp-style toolholders. With a maximum depth of cut of 0.197 inch and an inscribed circle of 0.500 inch, it suits medium to semi-roughing passes on gray iron, ductile iron, and similar ferrous materials. The A chip breaker style supports controlled chip formation at moderate feed rates. ANSI code CNMA431TT7015 and ISO code CNMA120404 TT7015 allow direct cross-referencing with toolholder catalogs and insert selection charts.

Key Features

• Solid carbide substrate with CVD-applied TiN/TiCN/Al2O3 multilayer coating for elevated wear and crater resistance
• CNMA diamond insert shape with 80-degree included angle for strong cutting edge geometry
• Four cutting edges per insert for extended tool life economy in volume turning
• 0.016 inch corner radius balances surface finish capability with edge strength
• Negative rake, neutral hand design compatible with standard CNMA clamp-style toolholders
• Primary application optimized for cast iron (ISO material group K)

Compatibility

Designed for use in CNMA-style clamp toolholders accepting a 0.500 inch inscribed circle insert with insert size code 431. Cross-references by ANSI code CNMA431TT7015 and ISO code CNMA120404 TT7015 for direct toolholder catalog matching.

Installation Notes

Installation is performed by qualified machinists or CNC tooling setup technicians. The machine spindle must be stopped and the turret or toolpost fully de-energized before seating or removing the insert. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer to secure the clamp; do not overtighten by feel alone. Inspect the insert pocket for chips or debris before seating a new insert to ensure full, flat contact and prevent premature edge failure.
