Asphalt Core Drill Bit - X300 - Asphalt

Designed for asphalt paving contractors drilling core samples and utility access points in fresh or aged asphalt surfaces. This 2-1/4 inch diameter core bit features a .155-inch segment thickness and 1 1/4-7 thread arbor connection for standard core drilling equipment. The diamond-impregnated segments cut clean holes through asphalt without tearing or crumbling the surrounding material. Works with gas-powered or electric core rigs on driveways, parking lots, and roadways. The X300 series delivers consistent cutting depth for testing compaction or creating penetrations for conduit and drainage. Built for paving contractors, highway maintenance crews, and site developers who need reliable cores in asphalt applications.
