How to Choose Tapered Drill Rod?
Specification Confirmation:
Firstly, ascertain the taper. The taper plays a crucial role in ensuring the stability of the connection and the efficiency of torque transmission between the drill rod and the drill bit. Common tapers utilized are 7 degrees, 11 degrees, and 12 degrees. Secondly, determine the appropriate diameter. For softer rocks, diameters ranging from Φ19 to Φ22 mm are suitable. Medium-hard rocks require diameters between Φ25 and Φ28 mm, while hard rocks necessitate diameters of Φ32 mm or larger. Lastly, establish the necessary length of the drill rod, which should align with the drilling depth and construction specifications. Our offerings include short drill rods (400-800 mm), medium-long drill rods (1000-1600 mm), and long drill rods (2000 mm and above).
Matching Rock Drill Specifications:
Ensure that the connection end specifications of the drill rod are compatible with the interface of the rock drill machine. Common connection end specifications include 22 x 108 mm and 25 x 108 mm.
Importance of Tapered Rock Drill Rods:
Tapered rock drill rods are indispensable tools in rock drilling operations. They boast high strength, wear resistance, reliable connections, and efficient operation. These rods are extensively utilized in a variety of drilling and rock crushing applications.
