Asphalt Core Drill Bit - X300 - Asphalt

Road maintenance teams cutting through asphalt for utility access and repair work need reliable core bits that handle abrasive material without premature wear. The Diamond Vantage X300 delivers a 4-1/4 inch diameter cut with a .155-inch segment height and 1 1/4-7 thread arbor connection for standard drilling equipment. The asphalt-specific segment design manages heat buildup and clears cuttings efficiently during wet or dry operation. This bit handles municipal water line taps, gas service installations, and pavement inspection cores where clean holes matter. The segment configuration cuts fast through hot mix and chip seal surfaces without wandering or binding. Built for asphalt contractors, utility crews, and municipal maintenance departments running handheld or rig-mounted core drills on street and parking lot projects.
