Description

Pneumatic rock drill bits can be divided into flat bit, cross bit and button bit. These drill bits are mainly used for hand-held rock drills. Pneumatic rock drill bits are suitable for mining of black metal mines(such as iron mine/ manganese ore), nonferrous metal mine(such as gold/silver/copper ore), marble and granite etc. Its drilling depth usually is 15m-18m in case of hardness grade F8-14. The pneumatic rock drill bits are suitable for hard rock drilling, it is widely used in drilling holes with a depth size less than 5 meters and diameter scope in 26-36 mm by light-duty hand held drills, major use in natural dimensional stone quarry for small hole drilling, block 's trimming and twice splitting for small blocks. All Pneumatic rock drill bits are made with high quality of raw material through special heat treatment. High quality designs, offer industry leading advantage and for more productivity,excellent straightness and hole clean quality.
