Diamond Core Bit - X300 - Hard Concrete

Engineered for HVAC installers drilling through post-tensioned concrete and heavily reinforced structural slabs where standard bits fail. The X300 hard concrete formula handles aggregate densities that burn out conventional diamond segments. This 5-inch diameter bit features a .155-inch segment thickness and 1¼-7 thread arbor connection for compatibility with standard core drilling rigs. The diamond matrix resists heat buildup during extended cuts through rebar-dense pours and high-PSI commercial grade concrete. Segment design provides consistent cutting speed without wandering or binding in hard material. Wet cutting required for proper segment life and performance. Built for drilling contractors and mechanical trades working in high-strength concrete applications where bit longevity directly impacts job costs.
