Litian Retrac Button Bit Features
Litian retrac button bits are made of high-quality steel and cemented carbide as raw materials, so they have a long service life. And the use of retrac bits minimize the loss of impact energy during transmission. In addition, the advanced button fixing technology makes the fixing force uniform and not easy to loose buttons. Meanwhile, the use of retract drill bits also ensures the perpendicularity of the borehole, so that the impact energy is concentrated on the rock and the drilling efficiency is improved.
Retrac Button Bit Application
No matter it is mining, rock drilling, or tunneling and blasting, Litian retract bits are suitable for all these situations.
