Top hammer drilling tools are a crucial part of modern drilling operations. From drifter rods to button bits, each component plays a specific role in the drilling process. In this article, we’ll take a closer look at the different types of top hammer drilling tools and their functions.
Drifter Rods
Drifter rods, also known as drifting rods, are used to drill straight holes into rock or other hard surfaces. They consist of a hollow steel tube, a shank, and a thread on both ends. A drifter rod connects the drill rig with the drilling tool (such as the bit or reaming shell) and transmits the rotational and percussive energy required to break down the rock.
Speed Rods
Speed rods are similar to drifter rods, but they are shorter and more rigid. Their primary purpose is to connect the drifter rod to the shank adapter or coupling sleeve and transfer energy to the drilling tool. Speed rods help to reduce energy loss and provide a stable connection between the drilling rig and the drilling tool.
Extension Rods
Extension rods are used to extend the reach of the drifter rod and drilling tool. They consist of a hollow steel tube with a thread on both ends. Extension rods can be used to reach deeper or harder-to-reach areas and are often used in underground mining operations or geological exploration.
Shank Adapters
Shank adapters are used to connect the drifter rod to the drilling tool. They also serve to transfer torque and impact energy to the tool. Shank adapters are available in different lengths and thread sizes to accommodate various drilling machines and tools.
Button Bits
Button bits are the most common type of drilling tool and are used for drilling holes into hard materials like rock, concrete, or asphalt. They feature tungsten carbide inserts, or “buttons,” on the bit face, which directly impact and break apart the material being drilled. Button bits are available in various designs, including spherical, ballistic, and conical.
Tapered Drilling Tools
Tapered drilling tools, also known as tapered equipment, are used for drilling small to medium-sized holes in hard materials. They feature a tapered shape that helps to reduce the energy required for drilling and increase drilling speed. Tapered drilling tools are available in a range of sizes and designs, including tapered bits, tapered rods, and tapered shank adapters.
In conclusion, top hammer drilling tools are critical components of modern drilling operations. With the right combination of drifter rods, speed rods, extension rods, shank adapters, button bits, and tapered drilling tools, drilling teams can improve their drilling efficiency and achieve better results.
