Prestressed Concrete Wet Diamond Core Bits

World Diamond Source® utilizes specialized crown segment technology to engineer premium Prestressed Concrete Wet Diamond Bits for high-speed drilling and long tool life. Moving away from standard widely spaced segments, our engineering features tightly spaced crown segments optimized to cleanly cut through hard concrete with reinforcement containing high-tension steel cables or prestressed strands. Formulated with a high-performance soft bond matrix, these production-grade bits maintain a constant, high-speed penetration rate without glazing or hanging up on high-tensile steel. Designed for maximum field productivity, the heavy-duty barrel features a removable cap that unscrews easily for quick core extraction and seamless pairing with core bit tube extensions with zero lead-time delays.
