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.
Tapered cross bits are suitable for mining of black metal mines(such as iron mine, manganese etc), nonferrous metal mine(such as gold, silver, copper etc), marble and granite etc.
1) Tapered connection: 7,11,12
2) Chisel bit diameter: 28-60mm
3) Technology:hot-pressing or welding
4) Bit Body: Short skirt and Long skirt
5) Tapered drill rod: H22/H25*108mm
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.
