When compared to similar rock drilling tools, LEANOMS's Threaded Button Bits have superior wear resistance, impact toughness, and drilling speed. The passivation time of the tools in the Threaded Button Bits series is longer—roughly 5–6 times longer than that of other drill bits. This helps to cut down on manual labor, speed up construction, and save auxiliary working hours.
In all forms of mining, drilling, quarrying, engineering, construction, drilling water wells, oil exploration, etc., our rock drilling bits are extensively used.
