Description

Technical Field

[0001] The utility model relates to the technical field of drill bit drilling processing, in particular to a taper cross drill bit drilling machine. Background Art

[0002] The cross drill bit is a drill bit for mining. It has strong resistance to radial abrasion. It is made of high-quality carbide and steel, and is used with various rock drills and machine drills. Different alloy grades are selected according to rock conditions.
