Abstract
The utility model relates to a twist drill. The twist drill comprises a knife handle and a knife body, wherein the knife body comprises a hole-expanding section and a guide section; the hole-expanding section is coaxially connected with the knife handle; the guide section is capable of shrinking along the inner diameter; and at least one slag outlet which is wound in a spiral manner along the rotary axis is formed on the peripheral surface of the knife body. The twist drill can be used for solving the problems that hole-expanding direction deviation appears and pain is caused to a patient as the twist drill is not only time-wasting and labor-wasting, but also capable of damaging perienchyma, and therefore, the twist drill realizes saving time and labor, and is precise in hole-expanding positioning.
