Abstract: A drill includes a cutting edge. The cutting edge has a point angle which is continuously decreased from a center-position point angle A (herein, 0°<A<180°) at a center position to a maximum-diameter-position point angle of 0° at a maximum diameter position. The cutting edge has a relief angle which is continuously decreased from the center position to the maximum diameter position. The cutting edge of the drill has a relief angle at the maximum diameter position. Hence, the cutting edge also serves as a cutting edge for reaming. The ridgeline and relief face of the cutting edge have no corner, thereby providing good wear resistance.

Abstract: A tool accessory used to apply different volumes of a cutting fluid to the tap under CNC control by causing the machine to undergo different pump cycles in which the rotational speed of the tool is increased above the tapping rotated and then quickly returned to the tapping rotation. The tool includes a tapping head, a reservoir filled with cutting fluid, a centrifugal force-reactive pump and at least two discharge nozzles. The pump includes a plurality of biased piston springs that are forced outward and store centripetal force when the tool is rotated at speeds above normal tapping speed. When the rotational speed of the tool is reduced, the piston springs overcome the centrifugal forces and force cutting fluid through the discharge nozzles. The volume of cutting fluid discharged is controlled by adjusting the viscosity of the cutting fluid, the tool's maximum speed, by using different size discharge nozzles, and by using different pump cycles.
