Dry Core Drill Bit with SDS Core Bit: The Ultimate Precision Tool for HVAC, Plumbing, and Highway EngineeringWhen Drilling Efficiency Determines Project ProfitabilityIn a shopping mall air conditioning retrofit project in Novosibirsk, Russia, contractors faced significant delays—23% longer than plan

Core drilling is a specialized technique used to create clean, perfectly round holes in hard construction materials like concrete, asphalt, masonry, and stone. Unlike impact drilling or chiseling, which rely on force and can damage surrounding structures, core drilling uses diamond-tipped hollow drill bits to grind away material with high precision. This allows engineers and contractors to perform modifications without compromising the integrity of the structure. The resulting holes are typically used for installations such as plumbing, wiring, HVAC systems, structural reinforcement, and inspection ports.
