KOR™ 5 High-Velocity Aluminum Roughing

Hey, I'm Nick here again at the technology lab at Kennametal in Latrobe, PA. Today I'm here with my buddy Jake again, and he's going to be demonstrating some cutting in aluminum with the MaxiMet™ 3-Flute End Mill and the new King of Roughing 5-Flute End Mill, also known as the KOR 5. Let's get to it! 

Milling Aluminum with KOR 5

So let's do some side milling starting without coolant. The KOR 5, unlike most end mills designed for aluminum cutting, has five cutting edges as opposed to the typical two or three.

Now let's turn the coolant on. The KOR 5 has a unique patented flute form for better chip formation and allows for improved coolant flow through the flute. It's also equipped with internal coolant technology which helps flush chips away from the cutting zone, improve lubrication, and reduce heat. Without internal coolant, flood coolant does not always provide its full benefits to the end of the cutter.

Now we're going to be helical ramping to start a pocket, and then continue to open up the pocket using dynamic milling. The KOR 5 is equipped with chip breakers for better chip management, a unique feature for aluminum tools. This helps avoid recutting chips and pockets and other small areas as well as eliminates issues with long chips tangling in the chip conveyer. Thanks so much for checking out the new KOR 5!
