Dry Core Drill Bit - Continuous Rim Core Bit - Concrete

Designed for HVAC contractors drilling clean penetrations through concrete floors and walls for pipe and conduit runs. This 4-inch continuous rim core bit features a .080-inch segment thickness that delivers consistent cutting performance in cured concrete applications. The continuous rim design provides smooth, chip-free holes with minimal vibration during dry drilling operations. Diamond segments are laser-welded to a steel core barrel for reliable bond strength under sustained jobsite use. The 10mm arbor connection fits standard handheld core drill motors up to 15 amps. Engineered for mechanical contractors, plumbers, and electricians who need accurate through-holes in concrete and masonry without water cooling systems.
