Product Details

Description

Retrac button bits are mainly used in loose rock mass with relatively broken rock. The retrac skirt design can assist in retrieving the drill tool, reduce the phenomenon of bit stuck and buried, and help improve the straightness of the borehole.
T38 Retrac Button Bits are the most important size for benching and underground long-hole drilling
We will choose to use tungsten carbide of T6/YK05，featuring good wear-resistance and toughness.

Performance

HENGLONG 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.

Application

Used in mining, rock drilling, or tunneling and blasting.
