The invention discloses a high-speed drilling bit, comprising a drill bit rigid body and drill teeth installed above the rigid body. The exterior surface of the drill bit rigid body is sleeved with an annular cylinder, which has grooves and water channels on its outer surface. Groove teeth are located in the grooves, and the inner surface of the annular cylinder has connection slots that match with connection axles on the exterior surface of the drill bit rigid body. The top surface of the drill teeth is equipped with raised excavation wings, and the groove teeth are triangular prism-shaped, evenly distributed in a stepped fashion within the grooves. The sides of the drill teeth are equipped with drilling edges, and the top side of the drill bit rigid body is curved. The top of the drill bit rigid body has several water permeation holes extending to the side of the bit, and the raised excavation wings have a rough texture. The configuration of an annular cylinder on the outer surface of the drill bit rigid body, with grooves and water channels, and groove teeth within the grooves, allows effective clearance of blockages caused by mud and sand, ensuring continuous operation of the drill bit.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
