Kennametal’s KOR 5 solid carbide end mill is designed for high-speed aluminum roughing in aerospace applications. The five-flute tool is said to allow for increased feed rates of 66% compared to three-flute tools. 

A tapered core, variable pitch design and 35-degree helix serve to eliminate chatter and tool deflection, the company says. Through-tool coolant flushes chips away while reducing heat. The tool’s chip splitter pattern is designed to break up long chips to avoid recutting while also contributing to better surface quality. 

The KOR 5 enables machining with low radial engagement but high depth of cut, resulting in higher metal removal rates than traditional methods, according to Kennametal. Use with the company’s Safe-Lock shanks increases the tool’s predictability and avoids pull-out at higher feed rates.
