Different top hammer rock drill bit sizes are used for various drilling applications, depending on the type of rock formation being drilled and the drilling method used. Here are some examples of how different top hammer rock drill bit sizes can be used in different applications.
Small diameter top hammer button bits (less than 2 inches): These are commonly used for drilling shallow blast holes, anchor holes, and exploration drilling in soft to medium-hard rock formations.
Medium-diameter top hammer button bits (2 to 4 inches): These are used for drilling medium blast holes in medium-hard to hard rock formations. They are also used for tunneling and drifting applications.
Large-diameter top hammer button bits (greater than 4 inches): These are used for drilling large blast holes in hard rock formations. They are also used in construction and mining applications, such as drilling shafts and tunnels.
Selecting the right top hammer rock drill bit size for the specific application is critical to ensure efficient drilling and maximum productivity. The rock drill bit sizes should be selected based on the hardness, density, depth of rock formation, and the drilling method being used. Additionally, other factors such as the type of rock drills and the power of the drilling machine may also influence the choice of button bit size.
