Abstract
A cutting tool for machining metal workpieces using polycrystalline diamond cutting surfaces with interspersed guide surfaces and chip evacuation surfaces. When machining holes in cast aluminum alloy workpieces it is found that aluminum machining chips adhere to guide surfaces and chip evacuation surfaces and mar the machined surface. It is found that when the guide and chip evacuation surfaces are coated with a diamond-like carbon material, aluminum chips do not mar the machined surfaces.
