94-165mm Five Blade Step Reamer Drill Bit

94-165MM FIVE BLADE STEP REAMER DRILL BIT PRODUCT INTRODUCTION Core Advantages This 94-165mm Five Blade Step Reamer Drill Bit is a large combined PDC Drill Bit and Polycrystalline Diamond Compact Bit that fully conforms to API Standard PDC Bit API industrial standards. As an integrated PDC Cutter Bit integrating pilot drilling and step reaming, its five symmetrical stepped blades expand boreholes in one single pass and greatly boost construction efficiency. The multi-step layered cutting structure reduces drilling resistance and stabilizes borehole straightness, avoiding repeated bit replacement. Uniform force distribution on five blades minimizes partial abrasion and extends service life. Different from single-purpose Oilfield PDC Bit for deep oil and gas well drilling, this heavy-duty Mining Drilling Bit is designed for one-step hole expansion in underground tunnels and large-scale geological exploration projects. Detailed Features The whole bit body is precision forged fro…
