Sandvik Coromant 5915050 Turning Insert CNMG432-SM H13A

Product Description

The SANDVIK COROMANT 5915050 is a solid carbide, uncoated turning insert in the CNMG432-SM H13A designation, part of the T-Max P series. It features an 80-degree diamond insert shape (shape code C), a 1/2-inch inscribed circle, a 1/32-inch corner radius, and a neutral hand orientation. The H13A carbide grade and SM chip breaker geometry are engineered for stable, controlled cutting action in demanding material groups. With four usable cutting edges and a clamp-and-pin holding method, this insert delivers consistent performance in precision turning operations on difficult-to-machine materials.

This insert is designed for turning applications in stainless steel (ISO material group M) as the primary workpiece material, with secondary suitability for superalloys and titanium (ISO material group S). The SM chip breaker geometry supports medium-depth finishing and semi-finishing passes where chip control and edge stability are critical. Typical install scenarios include CNC lathe and turning center operations in production shops, tool and die environments, and aerospace or industrial component manufacturing. Installation and indexing should be performed by a qualified machinist or toolroom technician following the machine tool manufacturer's torque and clamping procedures for CNMG-style inserts.

Key Features

• Solid carbide H13A uncoated grade optimized for stainless steel, superalloy, and titanium turning
• SM chip breaker geometry promotes controlled chip formation during semi-finishing and finishing cuts
• 80-degree diamond insert shape provides strong cutting edge geometry with good accessibility
• Four cutting edges per insert maximize tool life and reduce per-edge cost
• Clamp and pin holding method ensures secure seating and repeatable edge positioning
• Neutral hand orientation suits a wide range of toolholder configurations

Compatibility

Designed as an OEM-specification replacement or production insert for CNMG432 toolholders compatible with the T-Max P series platform. Suitable for holders accepting a CNMG insert style with a 1/2-inch inscribed circle, 3/16-inch insert thickness, and clamp-and-pin retention.

Installation Notes

Insert indexing and seating should be performed by a qualified machinist with the machine fully powered down and the spindle locked. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer for CNMG-style inserts — do not overtighten or use improvised tooling. Inspect the insert pocket and seating surfaces for chips or debris before indexing. Follow all applicable shop safety procedures and machine tool OEM guidelines during insert changes.
