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.
