Product Description
Milwaukee SDS+ Bit 9/16 in. x 10 in. x 12 in.
Model Number: 48-20-7484
The Milwaukee 48-20-7484 is an SDS+ rotary hammer drill bit in 9/16 in. diameter with a 10 in. working length and 12 in. overall length — an extended-length concrete drilling bit for the 9/16 in. specification in applications where through-wall penetrations, deep anchor embedments, or drilling position constraints require more working depth than standard-length bits can provide. The 9/16 in. diameter is used for specific structural anchor systems, through-bolt fasteners, and specialty concrete fastening applications where this precise bore diameter is called out by engineering specifications rather than the adjacent 1/2 in. or 5/8 in. standard sizes. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and the optimized helical flute engineering that maintains efficient concrete debris evacuation through the full 10 in. working depth for sustained drilling speed during production anchor installation operations.
The 12 in. overall length enables through-wall drilling in standard 8 in. CMU block construction with additional wall finish layers, structural anchor installations where longer embedment depth is required for the specific load rating, and drilling positions where the hammer must be placed further from the wall due to surrounding structure that prevents close positioning. At 9/16 in. diameter and 12 in. working depth, the flute volume and pitch specification are critical for maintaining adequate concrete debris transport capacity over the extended working depth — Milwaukee's flute geometry for extended-length bits at this diameter is specifically engineered to prevent hole choking at depth that would require frequent drill withdrawal to clear the hole during production drilling. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers.
See Milwaukee's complete 44 Magnum SDS+ catalog for all available diameters and lengths — for highest energy delivery in hard commercial concrete, Milwaukee's SDS Max lineup provides the larger shank format for demanding structural drilling applications.
