High-Performance Grooving Insert for Aluminum Machining
The MGMN ...-AL RT100 grooving insert is rigorously designed to meet the demands of machining soft and sticky materials. By combining uncoated K10-K15 carbide, a specialized AL geometry, and a ground, exceptionally sharp cutting edge, this tool creates excellent conditions for a clean and stable cutting process. The insert reliably prevents typical issues such as built-up edge and ensures low-friction chip evacuation during professional grooving and parting-off operations.

Applications
Thanks to its specialized design for long-chipping and soft materials, the MGMN-AL RT100 is an excellent choice for grooving and parting off aluminum, copper, brass, and various plastics. It is successfully utilized on CNC machines to produce precise grooves or to part off components with excellent, burr-free surface finishes.
Special features
The uncoated surface of the cutting insert drastically reduces material adhesion, which often leads to tool failure through built-up edge when machining aluminum. In addition, the pronounced positive rake angle ensures reduced cutting forces and enables a very smooth cut, which is highly beneficial when working with thin-walled or unstable workpieces.
