CARBIDE + Graph'X = hardness 1800 HV & 8000 HV (diamond) to machine laminated materials, graphite, reinforced polymer with glass or carbon fibres, all ceramics, glass.

The long neck form (radius + back taper) allows, according to the workpiece angle

to increase perceptibly the using depth of the tools

.
Combined with the new cut design, it reduces breakages and vibrations. So the high speed machining is efficient.
