Taper cross bits can be used under any rock drilling condition because of it's 
comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because carbide tips on cross bits doubled, which means carbides shape are cross type on drill bits. Taper cross bit is mainly used for hard or very hard rock formation. 

The drilling depth is usually 15m-18m of hardness grade F8-14.

It is widely used in drilling holes with a depth size less than 5 meters and diameter scope in 20-45 mm by light-duty hand hold drills, like Y6, Y10, Y24, major use in natural dimensional stone quarry for small hole drilling, block's trimming and 2nd splitting for small blocks. To match Hexagonal 22 mm and Hexagonal 12 mm’s tapered drill steel with 4/6/7/11/12 degree.
