difficult-to-machine material turning insert
Sumitomo Hardmetal Division
for difficult-to-machine materials
Catering for the increasing demands of manufacturers machining components in a growing range of lightweight wear resistant and often difficult to machine materials like nickel ferrite cobalt base heat resistant and titanium alloys - including Inconel 718 - we developed new grades AC510U a general purpose grade with a strong but sharp cutting edge suitable for roughing and finishing applications and AC520U a tough grade suitable for heavy interrupted cutting and the removal of scale. Both grades utilise our ultra hard Super ZX coat and promise substantial increases in tool life and productivity.
