Product Overview
Shops that burn through small end mills fast will get more mileage out of the 440-1406-ALTiN. This 9/64" diameter 4-flute square end mill is built with a double end, so once one side wears down, the tool still has a second cutting edge ready to go rather than heading straight to the scrap bin.
Because it carries an ALTiN coating, this one holds up better under heat than an uncoated version would, which matters more than people expect on longer production runs. The 30° helix keeps the geometry familiar and predictable, and the short cutting length is well suited to small slots, shallow pockets, and light side wall passes where the tool doesn't need to reach deep.
