Sandvik RNMG Model Turning Insert

Sandvik RNMG Model Turning Insert

The Sandvik RNMG turning insert is a double-sided round insert, typically featuring a nominal diameter of 12.7 mm and a thickness of 4.76 mm. With a zero-degree rake angle and a radial cutting edge form, this insert is suitable for roughing to semi-finishing operations. It supports high-performance grades such as 4325 and 4425, specifically designed for machining hardened steels up to HRC 50.

The insert is usually coated with multilayer TiAlN or CVD, providing wear resistance at temperatures up to 1050°C. The tungsten carbide substrate offers a hardness ranging from 1700 to 2000 Vickers. The nose radius varies from 0.4 to 1.2 mm, directly influencing surface finish and cutting force. Its symmetrical geometry allows the insert to be reused by rotating it, increasing tool life and cost-efficiency.
