Structural characteristics of thread button bit R32
A drilling button bit is a specialized type of drill bit characterized by its incorporation of numerous tiny, round, and highly durable tungsten carbide “buttons” or inserts embedded into its drilling face. These buttons function as the primary contact points, effectively crushing, chipping, and fracturing rock as the bit is rotated and pressed into the earth. This particular drill bit is ideal for applications in mining, construction, and various other drilling tasks. The R32 designation pertains to the thread size, specifically indicating a nominal diameter of 32 mm, ensuring compatibility with drill rods and shanks that adhere to this threading standard.

Structure Features of the R32 Drilling Button Bit
Button Design:
The defining characteristic of a button drill bit is the presence of buttons embedded in its head. These buttons are typically made of cemented carbide, such as tungsten carbide. The shape of the buttons allows for greater pressure to be applied over a smaller contact area when in contact with hard materials like rocks. In open-pit mining, for instance, the buttons act as mini “hammers,” facilitating the cracking and breaking of rocks.
Drill Body:
The body of the button drill bit is generally constructed from high-quality steel, serving as a sturdy support for the buttons. The design of the bit body ensures it possesses sufficient strength and toughness to endure the impact and torque encountered during drilling operations. The buttons are connected to the bit body through a specialized method, making it straightforward to replace worn-out buttons.
