While hammer hitting, button bit transmits energy directly to rock base and accomplish its function of cracking. Its bottom is round and embedded with tungsten carbide inserts which look like buttons. The upper part shapes like cylinder and finished with uneven spool lines for convenient connection to hammer. We can support various design of button bit.

A mechanical hammer, operated by pressed air. The upper part is connected to drill pipe from rotary head of drilling machine, lower part a bit. It is critical item to efficiency of drilling. As the most efficient tool for rock drilling, piston ,which alternately moves up and down at 1200 - 1800 times/min , in cylindrical housing hits a bit connected to drill pipe.
