Product Description
Milwaukee SDS+ Bit 5/32 in. x 2 in. x 4-1/4 in.
Model Number: 48-20-7700
The Milwaukee 48-20-7700 is an SDS+ rotary hammer drill bit in 5/32 in. diameter with a 2 in. working length and 4-1/4 in. overall length — a small-diameter, compact concrete anchor drilling bit for the 5/32 in. specification in the standard configuration used for light-duty concrete screw fasteners and small expansion anchors throughout commercial and residential construction. The 5/32 in. diameter is the standard pilot hole size for a common range of concrete screw anchors and small expansion fasteners used for conduit support brackets, equipment mounting, general concrete fastening, and sign installation where light-duty anchor load ratings are appropriate. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized fluting for consistent concrete drilling performance from first use through the bit's service life.
The compact 4-1/4 in. overall length is specifically advantageous for the tight-clearance drilling applications that small-diameter anchor work is most often required in — overhead concrete ceiling drilling where the shortest possible bit keeps the drill control point as close to the ceiling as the chuck allows, horizontal drilling near corners and structural elements where limited clearance prevents longer bits from being positioned, and confined-space drilling where the compact bit enables access to locations that extended-length bits cannot reach. The 2 in. working length serves the typical 1.5-2 in. embedment depths of light-duty concrete anchors in standard commercial ceiling and wall installations. For high-volume installations, Milwaukee offers this size in 25-pack bulk format at reduced per-bit cost compared to the individual unit purchasing format.
See Milwaukee's complete 44 Magnum SDS+ concrete bit catalog for all pack quantities at the 5/32 in. diameter and for extended lengths when deeper working depth is required.
