What makes TIT unique is their focus on local availability. With a 10,000 sq. ft. warehouse in Thimphu, they maintain inventory of popular sizes—like NQ and HQ impregnated bits—ensuring same-day dispatch for urgent orders. "When our drill bit failed mid-project in Haa, TIT delivered a replacement HQ impregnated bit within 4 hours," recalls a mining supervisor. "That kind of responsiveness saves us days of downtime."
TIT also partners with international manufacturers to import premium bits for specialized projects, such as high-temperature-resistant impregnated bits for geothermal exploration. Their client base includes government infrastructure projects, quarry operators, and even academic institutions conducting geological research.
Druk Rock Drilling Co. (DRDC) specializes in mining-grade drilling tools, with a focus on durability in harsh conditions. Their flagship product is the NQ3 impregnated diamond core bit , designed for deep mining exploration where rock formations are highly abrasive.
