China Factory 12 Degree Tapered Drill Rod Mining Drill Rod For Mining Tunneling
For drilling medium-hard to hard and abrasive rock formations,Taper angles of 11 and 12 degrees are used by a hand held drill machine like YT28B, YT29A, Y24, YT24, Mobile rock drill pneumatic and hydraulic in underground mining and for small hole drilling, equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc.
Drill rod is also called drill pipe, it is made by 55 SiMnMo steel. Tapered drill rods are used in granite and marble quarry, gold mine, railway, tunnel, etc. for drilling.Tapered drill equipment also provides a hexagonal chuck section to provide leverage for the rotation chuck bushing, which usually also has a forged collar to maintain the proper shank striking face position in the rock drill, and match a tapered bit at the socket end. Holes are typically drilled in 0.6 m increments to accommodate the air-leg feed length.
Taper Drill Steel is mainly used in small-hole drilling, such as stone quarrying, foundation drilling, tunneling, underground mining, road cutting, and trenching and so on, It can reduces the expense of impact energy, improves the drilling speed and efficiency, which can be used for drilling bore hole diameter from 23mm to 45mm usually.
