Before we used your bit for some application, and use KINGDREAM for the tough job. But over the time, we do not really see much difference, so we switch all the roller bit to you. This saves us lots of cost. Aram Attarian



This is a really a tough place for the piling. At some spot like this, we can normally reach 16 meters, now the bit already made 24 meters, it may reach to another 24 meters telling from this bit condition. The boss is happy.
