A rotating tool includes a tool body including a first end and a second end. A plurality of first helical flutes extend from the first end of the tool body, each first helical flute of the plurality of helical flutes defining a respective first cutting edge. A plurality of second helical flutes intersect with the first helical flutes at non-zero distances from the first and the second ends of the tool body, each second helical flute of the plurality of second helical flutes defining a respective second cutting edge. The first helical flutes and the second helical flutes are of opposite hands. The first helical flutes have a first pitch and the second helical flutes have a second pitch. A plurality of chip divider recesses are formed along each first cutting edge.
