Especially suited to machining hardened and high-strength steels. High rigidity allows for high feed rates and long service life, high angle of twist produces an excellent surface finish on the workpiece. The cutter is used for circumferential milling (finishing). At shallow depths, front cutting is also possible by reducing the feed rate by 50%.

T= dry		a_e = 0.02xd1
v_c = cutting speed [m/min]
f_z = feed per tooth [mm/z]		a_p = 1.5xd1
a_e = cutting thickness (radial)
a_p = cutting thickness (axial)
The cutting speeds listed refer to all tool types according to DIN 6527K or DIN6527L. For XL Series end mills, it is recommended to reduce the cutting speed by 30%.
