Abstract
PURPOSE: To prolong the life of a miniature drill by a method wherein the surfaces of marginal and flute parts of the captioned drill are coated with a hard coating layer, thereby the marginal part being protected and the deposition of chips to the flute part is prevented.
CONSTITUTION: The surfaces of the margin part 6 and the flute part 2 of the main body of a drill are coated, by an ordinary surface-coating method, with a hard coating layer 0.5W20μm thick composed of a single layer of one kind or a multiple layer of two or more kinds of groups selected from those which consist of the carbide, nitride, nitride carbide, carbonate and nitride-carbonate of the metal belonging to the 4aW6a groups of the periodic table, of aluminum oxide and further of the solid solution of these two kinds or more.
