Abstract:
This invention provides a drill bit specifically designed for basalt, including a first and a second drill bit, with the first drill bit mounted on the second. The second drill bit features radially protruding blades or wings on its side, equipped with cutting units for slicing and breaking rock. At least two blades are provided, with reinforcing ribs on one side of each blade. This design effectively enhances heat dissipation and facilitates the disassembly and replacement of the drill bit, thus improving its service life. The reinforcing ribs on the blades increase structural strength and aid in the removal of debris, reducing the risk of jamming and obstruction during drilling, and effectively improving drilling effectiveness and efficiency.
