| description | The invention discloses a drill bit for a printing and punching device. The drill bit comprises a drill bit body; a hollow cavity is formed in the drill bit body; a water control device is arranged atthe bottom of the hollow cavity; and the water control device comprises a water passing port formed in one side of the bottom of the hollow cavity, a plug for blocking the water passing port, and a spring connected with the plug and fixed on the other side of the bottom of the hollow cavity. The drill bit further comprises a drill bit tip end; multiple holes are formed in the drill bit tip end; and the holes communicate with the water passing port through a water passing channel. Water is introduced into the hollow cavity; when the drill bit works, due to the effect of centrifugal force, thewater flows out from the water passing port, passes through the water channel, and flows out to the drill bit tip end from the holes; when the drill bit tip end works, the drill bit tip end is easy todamage by heating; the wat |
