Summary:The invention discloses a durable drilling head for a well cellar type puncher. The durable drilling head comprises a connecting rod (1) with a conical end part, wherein two arc-shaped blades (2) buckled in a staggered manner are connected to the connecting rod (1), a rotating shaft connecting hole (3) is formed in the upper end of the connecting rod (1), and each arc-shaped blade (2) is formed by cutting off a slope angle in the 1/2-2/3 position of the long side of 1/4-1/3 of the cylindrical surface; the connecting rod (1) is connected with the arc-shaped blades (2) in a welding manner. Compared with existing hollow drilling heads, the durable drilling head has the characteristics that the drilling head is more durable, the service life of the drilling head can be prolonged, the size can be adjusted according to the diameter of a well cellar type transplantation hole, the production cost can be reduced, and the drilling head is safer and more reliable. 本发明公开种井窖式开孔器的耐用钻孔头，它包括端部为锥形的连接杆（1），在连接杆（1）上连接有错位对扣的两片弧形刀
