HAWK-BEAK-TYPE NANO-DIAMOND-COATED HARD ALLOY DRILL BIT

摘要

Disclosed is a hawk-beak-type nano-diamond-coated hard alloy drill bit, the hawk-beak-type nano-diamond-coated hard alloy drill bit comprising a tool handle (1) and a tool bit (2). An outer surface of the tool bit (2) is provided with a spiral groove (3); one end of the tool bit (2) that is away from the tool handle (1) is provided with a drill point angle (4); the drill bit is provided with two hawk-beak-type notches (5) symmetrically by 180 degrees at the tip of a first rear tool face; the drill bit has a thinned chisel edge design (6) at the center of the drill bit; one end of the tool handle (1) that is away from the tool bit (2) is provided with a chamfer (7); and the outer surface of the drill bit tool bit (2) is provided with a nano-diamond coating. The hawk-beak-type nano-diamond-coated hard alloy drill bit mainly solves the problem of hole machining of PCB super-hard plates in network communication applications of 5G and later.
