TAPER CROSS BIT

Tapered cross bits connect tapered drill steel of rock drill for drilling holes.The 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.

Taper cross bit is 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. Its drilling depth usually is 15m-18m in case 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.

All tapered cross bits are made with high quality of raw material through special heat treatment, The deliver capacity are very strong and can completely meet customer’s requirements on delivery design.
