Kennametal has released the KOR 5 solid carbide end mill—its latest innovation in high-velocity aluminum roughing. Designed for maximum productivity in aerospace machining, with this five-flute end mill table feed rates increase up to 66 percent compared to commonly used three-flute tools—redefining productivity for aircraft manufacturers and their suppliers.
KOR 5 is aimed at removing large amounts of metal and getting it away from the work zone as quickly as possible:
-Tapered core, variable pitch design, and 35 deg helix – eliminates chatter and tool deflection
-Coolant through the tool – flushes chips away while reducing heat.
-Unique chip splitter pattern – designed to break up long chips, eliminating re-cutting, but still contributes to high surface qualities.
The tool has the potential to become the new standard for machines utilising CAD/CAM tool paths.
KOR 5 has more active contact points versus a 2-fluted or 3-fluted end mill because it is a 5-fluted end mill, which creates improved stability and eliminates chatter on even the heaviest cuts.
Applying the tool with low radial engagement, but high depth of cut results in much higher metal removal rates than traditional methods.
And to assure predictable, no pull-out performance at maximum feed rates, the KOR 5 is available with Safe-Lock shanks.
“Slotting, deep pocketing, dynamic milling—whatever your aluminum application, KOR 5 can do it faster”, said Thilo Mueller, Manager for Solid Carbide End Milling.
