Diamond Non-Coring Drill Bit

KBJZ diamond non-coring drill bit (also known as full-face diamond bit) is designed for non-core drilling operations. It crushes rock formation directly without recovering core samples, greatly boosting penetration rate for water well drilling, geological exploration, oil & gas shallow drilling, mining, slope stabilization, grouting boreholes and civil engineering projects. This non-core diamond bit is sintered with large-grit diamond grains . The coarse diamond grit features sufficient protrusion and firm matrix retention, delivering outstanding abrasion resistance and impact toughness. It works reliably in medium-hard to hard rock, fractured zones, sandstone and limestone. Optimized internal waterways ensure stable flushing and cuttings removal, preventing bit balling and slipping in abrasive formations. High-strength alloy bit body is adopted. Standard thread connections including REG, NC, NTW, HTW are available to fit most water well rigs, geologic drill rigs and anchor drilling machines. We supply stock sizes and accept custom diameters for drilling contractors, exploration companies and wholesale importers worldwide.
