Learn why DTH drill bits wear too fast, how to diagnose wear patterns, optimize drilling parameters, select carbide grades, and reduce cost per meter.

In rock drilling operations, efficiency and tool longevity are critical factors that directly affect project costs and productivity. One of the essential components in rock drilling systems is the shank adapter, a crucial transmission connection between the rock drill and the drill rod. The primary function of the shank adapter is to withstand the impact energy and torque transmitted by the rock drill, ensuring effective energy transfer for drilling.

A rock drill rod is a fundamental component of a rock drilling system, connecting the drill bit and the shank adapter. It serves as the medium for transmitting the driving force from the rock drill to the drill bit, facilitating the drilling process through a threaded connection. Rock drill rods and drill bits come in various types, depending on the application and drilling conditions. However, in terms of service life, drill rods generally last longer than drill bits.
