64mm T38 Retractable Button Bit With Retractable Skirt Design For Fractured Rock Drilling
For fractured and unstable rock formations, ordinary threaded drill bits often experience jamming during extraction. Henglong's 64mm T38 retractable button bit offers stable drilling performance and smooth retraction, effectively reducing downtime at construction sites.
This top hammer retractable drill bit features an optimized inverted cone drill body structure, specifically designed for drilling in fractured rock formations to effectively prevent jamming. The bit is fitted with high quality YK05 carbide beads using a hot fitting process, balancing drilling speed and wear resistance. Precision machined T38 threads ensure a tight fit with matching drill rods, guaranteeing stable impact energy transmission and consistent straightness of drilled boreholes.
- Telescopic drill body structure significantly reduces the risk of stuck drill bits and facilitates easy retraction in fractured rock formations
- High quality 42CrMo alloy steel drill body, professionally heat treated for strong deformation resistance
- Carbide teeth are wear resistant and durable, with low probability of chipping or breakage, resulting in longer service life
- Standard 64mm diameter, compatible with T38 threaded drill rods and hydraulic rock drills
Underground mining blast hole drilling, tunnel excavation, anchor bolt drilling, quarrying operations, and rock anchoring projects. Suitable for medium hard to hard fractured rock formations.
