FGT SOLID CARBIDE END MILLS
FGT BALL NOSE- AND CORNER RADIUS END MILLS
Innovations – for 3-D-machining of shallow contours and profiles:
new ball- and corner-radius geometry
improved transition curves between
shank and cutting edge
new coating PVTiH
new carbide substrate UMGC
reduced diameter- and radius-tolerances
avoiding vibrations
remarkably increased tool-life
better rigidity
for machining of:
tool steels
die steels
hardened steels up to 58 HRC
