75-113mm Five Blade Reamer Drill Bit

75-113MM FIVE BLADE REAMER DRILL BIT PRODUCT INTRODUCTION Core Advantages This 75-113mm Five Blade Reamer Drill Bit is an integrated PDC Drill Bit and Polycrystalline Diamond Compact Bit manufactured under API Standard PDC Bit API specifications. As a multi-functional PDC Cutter Bit combining pilot drilling and hole reaming, its five symmetrical cutting blades evenly expand boreholes in one single drilling pass, greatly improving construction efficiency. The five-blade layout distributes drilling pressure uniformly to reduce unilateral abrasion and stabilize borehole trajectory. The integrated pilot and reaming structure eliminates frequent bit replacement, cutting down construction downtime. Unlike single-purpose Oilfield PDC Bit designed for deep oil and gas well excavation, this all-in-one Mining Drilling Bit is ideal for one-step hole expansion in geological prospecting and underground tunnel engineering. Detailed Features The whole bit body is precision forged from high-…
