Milwaukee SDS-Max Core is designed for efficient drilling of large holes where the depth is relatively shallow. Milwaukee’s 1-piece carbide tipped core bits cut a kerf only, requiring the operator to remove the inside core before drilling deeper. For optimal use, a centering bit (48-20-5495, not included) is , and the centering bit can be removed using the drift key 48-20-5497. These core bits are available with SDS Max or spline shanks and 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 material pulverization for faster drilling. The 1-piece design maximizes energy transfer, while the thick wall core body ensures durability even in large hammers. Additionally, the fluted core exterior reduces friction loss and accelerates debris removal, making it a reliable choice for demanding drilling tasks. Model Number: 48-20-5434
