HC Drilling Tools

HC drilling tools are made of high performance alloy steel, featuring in superior drilling quality, high stability and long service life. The top-hammer tools are designed and produced to transmit high-frequency impact energy into the rock and minimize energy loss to improve the rock breaking rate, penetration rate, and productivity.

HC provides standard and heavy-duty series top-hammer drilling tools, suitable for drilling in soft rock, medium-hard rock, hard rock, and various complex mixed rock working conditions. The drill bit, drill rod, coupling sleeve, and shank adapter are connected by their threads to form a rock drill assembly. The commonly used thread forms include rope thread and trapezoidal thread.
