Milwaukee SDS Max Thick Wall Core Bit 18 in. Adapter Shank

The SDS-Max Thick-Wall Core Bit 18-Inch Adapter Shank extends the reach of your core bits by 18 inches. This Milwaukee? adapter fits Milwaukee rotary hammers. You can attach core bits between 1-1/2 inches to 6 inches in diameter. Note that since core bits only drill out with their edges and this Milwaukee adapter is not hollow， it does not extend the bit's cutting length， only its reach. Its specialty carbide construction increases its durability to provide you with long-lasting performance. Use the extension to reach into tricky spaces and cut holes in concrete pieces as deep as the length of the bit. The SDS-Max connection means that the rotary hammer transfers its power directly to the bit instead of the chuck， which allows you to drill quickly.
