Ingersoll Cutting Tools 5700296 Ceramic Turning Insert CNGA432

Product Description

The INGERSOLL CUTTING TOOLS 5700296 is an uncoated ceramic turning insert in the CNGA style, designed for precision metal removal on CNC and manual turning equipment. Carrying the manufacturer grade AB30 and conforming to ANSI code CNGA432AB30 (ISO CNGA120408 AB30), this insert features an 80-degree diamond shape with a negative rake angle and a neutral hand orientation. It offers four usable cutting edges per insert, providing reliable tool life in high-demand production environments. The 1/2-inch inscribed circle and 3/16-inch thickness deliver the structural rigidity required when machining abrasive or difficult workpiece materials at elevated surface speeds.

This insert is engineered for turning operations on cast iron and hardened steel, workpiece material codes K and H respectively. The uncoated ceramic substrate performs well at higher cutting speeds where coated carbide may fall short, making it a practical choice for finish and semi-finish turning passes in production shops, job shops, and toolroom settings. It is held in place by a clamp-style toolholder and is compatible with standard CNGA-seat toolholders accepting a 1/2-inch inscribed circle insert.

Key Features

• Uncoated ceramic insert grade AB30 for high-speed cutting of cast iron and hardened steel
• 80-degree diamond insert shape (shape code C) with negative rake for increased edge strength
• Four cutting edges per insert for extended service value in production turning
• 1/32-inch corner radius for controlled surface finish on finish and semi-finish passes
• Clamp-style holding method compatible with standard CNGA-seat toolholders
• Neutral hand orientation for flexible left- or right-hand toolholder setups

Compatibility

Designed for use in standard CNGA-style clamp-type turning toolholders that accept a 1/2-inch inscribed circle insert with a clearance code N and tolerance code G seat. Primary workpiece materials are cast iron (material code K) and hardened steel (material code H).

Installation Notes

Turning insert replacement should be performed by a qualified machinist or tooling technician with the machine powered off and all axes at rest. Ensure the toolholder pocket and clamp are free of chips and wear before seating the insert. Clamp screws should be tightened to the toolholder manufacturer's specification. Verify insert orientation and edge selection before resuming cutting operations.
