Ang Hunan FengSu Drill Bit Co., Ltd. ay may 5 independiyenteng mga pagawaan at daan-daang mga empleyado. Nakipagtulungan ito sa China University of Geosciences at kumuha ng dose-dosenang mga propesor at doktor upang magsaliksik ng ultra-wear-resistant na materyal, na may higit sa 50 aplikasyon para sa mga patente. Ito ang gumagawa ng mga produkto ng drill bit na epektibo at matibay upang matugunan ang iba't ibang pangangailangan sa pagbabarena tulad ng natural gas, langis, eksplorasyon ng karbon, eksplorasyong heolohikal, at mga balon ng tubig. Tiyak na gagana nang perpekto ang aming mga produkto sa lahat ng uri ng mga kapaligiran ng bato. Sumusunod kami sa konsepto ng walang humpay na teknolohikal na inobasyon, mahigpit na kontrol sa kalidad, at pagtiyak ng pagiging maaasahan at propesyonalismo sa mga produktong aming inaalok.
