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.
Tianyue 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.
When drilling in confined spaces or working with smaller rigs in hard or fractured rock, precision and reliability are critical. That’s why experts across mining, tunneling, and geotechnical industries choose R38 Retrac Button Bits—designed for accuracy, durability, and fast penetration in challenging drilling conditions.
Whether you're developing narrow tunnels, stabilizing slopes, or anchoring foundations, R38 Retrac Button Bits offer the control and cutting power you need—every single time.
R38 Retrac Button Bits are compact, high-strength top hammer drill bits designed with an R38 thread system and a specialized Retrac body structure. This retrac design ensures better reaming ability and optimal hole straightness in fractured or loose rock formations, reducing the risk of hole deviation or bit jamming.
Ideal for 45mm to 76mm hole diameters, R38 Retrac Button Bits are built for small to mid-size drilling rigs operating in tight spaces or underground environments where maneuverability matters.
Exceptional Hole Accuracy
The retrac shoulders guide the bit and help ream through collapsed rock or unstable areas, ensuring straight, consistent holes.
Fast Penetration & High Efficiency
Tungsten carbide buttons—spherical or ballistic—provide excellent impact resistance and cutting performance for faster drilling.
Superior Wear Resistance
Made from heat-treated alloy steel, R38 Retrac Button Bits withstand extreme conditions and deliver long service life, even in abrasive environments.
Secure Thread Fit
The R38 thread connection ensures tight engagement with rods, enabling high torque transfer and minimizing vibration loss.
Ideal for Compact Drilling Systems
Lightweight, short-body design allows excellent control in confined or underground locations without sacrificing performance.
Underground Mining & Tunnel Development
Slope Stabilization and Rock Bolting
Foundation Anchoring in Civil Projects
Bench Drilling in Narrow Sites
Geotechnical Investigations
R38 Retrac Button Bits are the go-to tools when space is tight, rock is fractured, and drilling precision is non-negotiable.
