To select the correct SDS-Max drill bit, match the shank type to your hammer drill—SDS-Max is for larger rotary hammers. Consider the required hole diameter (e.g., 1 1/4 in) and drilling depth (e.g., 10 in). For reinforced concrete, use a carbide-tipped bit like the MILWAUKEE 48-20-3970. Always verify compatibility with your tool's chuck.
