75mm 3-Wing Step Concave Bit

75MM 3-WING STEP CONCAVE BIT PRODUCT INTRODUCTION Core Advantages This 75mm 3-Wing Step Concave Bit is a medium-size PDC Drill Bit and Polycrystalline Diamond Compact Bit produced in strict accordance with API Standard PDC Bit API criteria. As a professional PDC Cutter Bit for geological prospecting, its special step concave three-wing design realizes layered rock breaking, greatly improving drilling penetration speed and positioning stability. The stepped concave structure effectively holds rock debris and accelerates flushing discharge, avoiding bit blockage in mixed soft and medium-hard strata. Even load sharing on three cutting wings balances unilateral abrasion and extends service intervals. Different from heavy Oilfield PDC Bit for deep oil and gas well exploitation, this lightweight Mining Drilling Bit fits portable drilling rigs for narrow underground shallow drilling operations. Detailed Features The bit main body is precision forged from high-toughness alloy steel w…
