Where More Flutes Make Sense

A tool with many flutes can be effective for achieving a productive metal removal rate in titanium, where speed and chip load are constrained.

MAG’s cryogenic machining is an extreme response to the danger of heat in machining titanium, but the company says heat has always been the enemy. The company offers 20-flute end mills for titanium because the large number of flutes offers a way to cut at low surface speed and light depth of cut, but still maintain a high metal removal rate through a high inch-per-minute feed rate.
