Thanks to consistent and stable quality and stand in customers' shoes for over 20 years, Leanoms' Drill Thread Bits have been sold throughout the world. Leanoms as the leading manufacturer and servicer, provides a wide variety of Drill Thread Bits at reasonable and competitive thread button bit prices compared with international brands such as Sandvik, Epiroc.
Retrac button bits:
Retrac Button Bits are typically used in loose rock masses with relatively broken rocks, the retrac skirt design can help with drill tool retrieval, lessen the occurrence of bits getting trapped and buried, and enhance borehole straightness. Leanoms Retrac Button Bits are made of imported steel and cemented carbide as raw materials, so our Drill Thread Bits are longer-lasting. Retrac bits are used to reduce impact energy loss during transmission. Furthermore, thanks to modern button-fixing technology, the fixing force is homogeneous and difficult to lose buttons. Additionally, the use of retract drill bits also ensures the perpendicularity of the borehole, which concentrates impact energy on the rock and increases drilling efficiency.
Our Mission:
Concentrating on drilling customers requirements and challenges, and work with clients to supply the most cost-effective hard-rock drilling solutions for their needs.
