Ingersoll Cutting Tools 5523571 Turning Insert CNMA432

Product Description

The INGERSOLL CUTTING TOOLS 5523571 is a CNMA432 TT7015 grade solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Featuring a CVD-applied TiCN and Al2O3 multilayer coating, this insert is engineered primarily for machining cast iron workpieces. The 80-degree diamond shape (CNMA insert style) provides a strong cutting geometry with a negative rake angle and a 0-degree relief angle. With a 0.031-inch corner radius and a maximum depth of cut of 0.236 inches, this insert suits moderate to heavy turning operations where edge strength and wear resistance are critical.

This insert is suited for production turning environments in job shops, aerospace component suppliers, and automotive part manufacturers where cast iron is a primary workpiece material. The CNMA432 format fits standard CNMA-style toolholders with clamp-style insert retention. With four cutting edges per insert, tooling cost per edge is kept low in high-volume operations. Licensed machinists and CNC operators working with gray iron, ductile iron, and similar ferrous castings will find this insert well-matched to their application requirements.

Key Features

• CVD-coated TiCN and Al2O3 multilayer finish for extended wear resistance on cast iron
• 80-degree diamond insert shape provides strong nose geometry for heavy interrupted or continuous cuts
• Negative rake angle with 0-degree relief (clearance code N) supports rigid clamping and stable cutting
• Four usable cutting edges per insert reduce per-edge tooling cost
• 0.031-inch corner radius balances surface finish quality with edge strength
• Maximum depth of cut of 0.236 inches suitable for moderate to heavy roughing passes

Compatibility

Designed for use in CNMA-style clamp-type toolholders accepting a 432 insert size. ANSI code CNMA432TT7015; ISO code CNMA120408 TT7015. Optimized for cast iron (ISO material group K) turning applications.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping specifications. Ensure the toolholder pocket and clamp are clean and free of chips before seating the insert. Power down and lock out the machine spindle before performing any insert change. Do not use damaged or chipped inserts, as this can cause unpredictable tool failure during cutting.
