Asphalt Core Drill Bit - X300 - Asphalt

Road maintenance teams drilling core samples through asphalt surfaces rely on this 4-inch wet core bit to power through hot mix and compacted layers. The X300 features a .155-inch segment width designed specifically for asphalt applications, with a 1 1/4-7 thread arbor connection that fits standard core drilling rigs. Diamond Vantage engineers this bit to handle the abrasive nature of aggregate-filled asphalt without segment loss or wandering cuts. The wet drilling design keeps temperatures controlled during extended boring operations, maintaining cutting speed through multiple cores per job. Delivers clean cylindrical samples for pavement analysis and utility locating work. Built for asphalt contractors, highway departments, and testing labs running daily core extraction on roads and parking surfaces.
