Core drill water swivel
Our asphalt core drill bits are designed with all of the Department of Transportation’s and Testing Companies in mind. We utilize the newest technology and the highest diamond concentration on the market to ensure the fastest drilling speed and longest life than any other bit on the market; in asphalt and other abrasive materials.
Our newest barrel design for core bits has revolutionized the coring industry! Not only does the top of the core barrel unscrew for fast and safe removal of core samples, but now we have barrel extension’s to allow deeper drilling: up to 6 feet without removing the bit from the hole.
