rock drill rods

Produce Hexagonal and round cross sections, Hexagon rods are more rigid, heavier and transfer energy more efficiently, while increasing flushing. Round rods are generally lighter than hexagonal rods and are normally used in extension drilling applications.

Cemented carbide tapered button bits are made from high quality cemented carbide, produced with advanced technology and equipment, having different types bits, such as tapered chisel bit, tapered cross bit and tapered button bit which connected with tapered drill rod well for drilling hole, inserting depth is 25-30mm, obtaining maximum drilling speed, keeping stable and lowering rock drill working parameters so that prevent single button under overload then cause the button broken or lost

Operation process: 1.Connect the power supply and let the equipment run empty for 1-2 minutes. 2.Move the handle to the chuck close to the support plate A. 3.Marking the end of the distance brazing rod at the end of 330mm. 4.Put the rod into the chuck.The identification of the step 6.3 brazing rod is aligned with the outer edge of the support plate A, and the work piece is tightened. 5.Slowly moving the handle, the speed of about 1-1.2mm/seconds, Repair of brazing rod at uniform speed.
