Introducing the KOR™ 5: The King of Roughing

Secure, strong, and extremely fast, the KOR 5 from Kennametal takes aluminum roughing for
aerospace to an entirely new level

Kennametal today announced its latest innovation in high-velocity aluminum roughing, the KOR 5
solid carbide end mill. 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° 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 utilizing 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.
