Milwaukee 2-5/8Inx22In SDS Max Core Bit is designed for drilling large holes with relatively shallow depths. This one-piece carbide-tipped core bit cuts a kerf only, requiring the operator to remove the inside core before deeper drilling can continue. For optimal use, it is to pair with the centering bit 48-20-5495 (sold separately) and use drift key 48-20-5497 to remove the centering bit from the core bit. Available in SDS Max or spline shanks, these core bits come in various diameters from 1-1/2 inches to 6 inches, with overall lengths of 11-3/8 inches or 22 inches and a drilling depth of 3 inches. The asymmetric tooth pitch with alternating tooth geometries enhances faster material pulverization. Its one-piece design maximizes energy transfer, while the thick wall core body ensures durability even when used with large hammers. Additionally, the fluted core exterior minimizes friction loss and speeds up debris removal for efficient drilling performance. Model Number: 48-20-5414
