Iscar 5700427 Ceramic Turning Insert IN23 Isoturn

Product Description

The ISCAR 5700427 is a DNGA-style ceramic turning insert engineered for precision metal removal in demanding turning applications. It features an IN23 manufacturer grade with an Al2O3 and TiCN finish applied over a ceramic substrate. The insert has a 55-degree diamond shape, a 0.5-inch inscribed circle, a 0.0157-inch corner radius, and an overall length of 0.6102 inches (15.5 mm). Holding is accomplished via clamp or pin methods. This insert is installed by machinists and CNC turning specialists working with high-wear materials where ceramic cutting performance is required.

This insert is designed for turning applications involving cast iron and hard materials, corresponding to ISO workpiece material codes H and K. It is part of the Isoturn series, which is suited for external and internal turning operations where consistent chip control and insert geometry are critical. The chip breaker code T and DNGA geometry make it appropriate for roughing and semi-finishing passes at controlled depths of cut up to 0.1181 inches (3.00 mm). Typical use is in production turning environments on CNC lathes and turning centers.

Key Features

• 55-degree diamond (DNGA) insert shape with 0 degrees relief angle for rigid clamping setups
• 0.5-inch inscribed circle and 0.6102-inch insert length for consistent engagement geometry
• Maximum depth of cut of 0.1181 inches (3.00 mm) suitable for roughing and semi-finishing
• Compatible with clamp and pin holding methods for secure insert retention
• Conforms to ISO 13399 standards for interchangeable cutting tool data representation

Compatibility

Designed as an OEM-style replacement insert for toolholders accepting DNGA 431 geometry with clamp or pin holding, consistent with Isoturn series toolholder specifications.

Installation Notes

Insert installation and replacement should be performed by qualified machinists or tooling technicians with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and clamping hardware specified for the DNGA-style toolholder to seat the insert properly. Inspect the insert pocket and clamping surfaces for debris or wear before seating a new insert. Follow the toolholder manufacturer guidelines for insert indexing and secure retention before resuming cutting operations.
