Sumitomo 192RAJX CNMA434 AC415K Carbide Turning Insert

Product Description

The SUMITOMO 192RAJX is a solid carbide turning insert in the CNMA style, designed for precision metal cutting on CNC lathes and manual turning centers. It carries the AC415K manufacturer grade with a CVD-applied proprietary FF coating finish that improves wear resistance and surface finish consistency. The insert features an 80-degree diamond shape with a negative rake angle and a 0.0625-inch corner radius. With a 0.5-inch inscribed circle and a thickness of 0.1875 inches, this insert is sized for medium to heavy-duty turning passes. It is installed using a clamp and pin holding method and conforms to ANSI and ISO 13399 standards. Machinists and tooling technicians specify this insert for production turning operations requiring consistent tool life.

The 192RAJX is suited for turning applications in general machining environments, including operations on cast iron workpieces, which aligns with its K-grade secondary workpiece material designation. The CNMA434 ANSI code and CNMA120416 ISO code make cross-referencing to tool holder systems straightforward. It fits standard CNMA-style tool holders that accept a 0.5-inch inscribed circle insert. This insert is appropriate for both roughing and finishing passes where a negative-rake geometry is preferred, and it is commonly used in job shops and production machining facilities.

Key Features

• Solid carbide construction with CVD-applied AC415K grade coating for extended wear life
• 80-degree diamond insert shape with negative rake angle for strong cutting edge geometry
• 0.0625-inch corner radius provides a balance between edge strength and surface finish
• Clamp and pin holding method ensures secure seating in compatible CNMA tool holders
• Conforms to ANSI and ISO 13399 standards for interchangeability and traceability
• K-grade designation confirms suitability for cast iron secondary workpiece materials

Compatibility

Designed as an OEM-style replacement insert for CNMA-style tool holders accepting a 0.5-inch inscribed circle, conforming to ANSI code CNMA434 and ISO code CNMA120416.

Installation Notes

This insert is installed by qualified machinists or tooling technicians. Power down and lock out the machine before changing inserts. Seat the insert fully against the tool holder pocket and confirm the clamp and pin are properly engaged before resuming operation. Inspect the pocket and clamp components for wear or damage each time an insert is indexed or replaced.
