Latrobe, Pennsylvania – Kennametal’s latest innovation in high-velocity aluminum roughing, the KOR 5 solid carbide end mill, is designed for maximum productivity in aerospace machining. With this 5-flute end mill, table feed rates increase up to 66% compared to 3-flute tools.

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

Because it is a 5-fluted end mill, KOR 5 has more active contact points versus a 2-fluted or 3-fluted end mill, improving stability and eliminating chatter on 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.

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.
