Core Bit Drill - Premium Black Large Diameter Wet Core Bits - Solid Back

Large-diameter wet core drilling through structural concrete and reinforced masonry demands bits that can handle extended run times without segment loss. These solid back wet core bits from Diamond Products deliver consistent performance on high-horsepower rigs used for HVAC penetrations, elevator shafts, and large utility chases. The solid back design provides maximum segment support during deep cuts, reducing vibration and maintaining straight bore paths through rebar-dense pours. Wet drilling keeps diamond segments cool and flushes slurry from the cut, extending bit life on demanding commercial and industrial projects. Engineered for concrete cutting contractors and mechanical trades running heavy-duty core rigs on job sites where bore diameter and depth matter.
