Product Description
Milwaukee SDS+ Bit 3/16 in. x 14 in. x 16 in.
Model Number: 48-20-7416
The Milwaukee 48-20-7416 is an SDS+ rotary hammer drill bit in 3/16 in. diameter with a 14 in. working length and 16 in. overall length — the deep-reach, small-diameter configuration for 3/16 in. anchor and concrete fastener drilling in thick concrete sections, through-block penetrations, and deep embedment installations where the standard and intermediate length 3/16 in. bits cannot achieve the required hole depth. The 3/16 in. diameter is the standard pilot hole size for common concrete screw anchors and light-duty expansion fasteners used throughout commercial and residential construction, and the 16 in. overall length extends the drilling reach of this common fastener size into applications where structural thickness, anchor embedment specifications, or drill positioning constraints require a bit length that standard configurations cannot provide. Milwaukee SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks — at the small 3/16 in. diameter and 16 in. extended length, the vacuum-brazed carbide bond and precise flute engineering are particularly important for maintaining bit performance and structural integrity throughout the full working depth of deep drilling operations.
The extended 16 in. overall length of this bit is the specification required for drilling through standard 12 in. CMU block walls from a position offset from the wall face, for concrete screw anchor installations in thick foundation walls and grade beams where long embedment depth is specified for high pull-out load resistance, and for through-penetration drilling from one side of a thick concrete structural element without repositioning the drill setup to drill from the other side. Milwaukee's optimized helical flute geometry maintains effective concrete debris evacuation from the base of the hole through the full 14 in. working depth — the flute pitch and volume are specifically engineered for the 3/16 in. diameter to provide adequate debris transport capacity over this extended working length without the choking and bit binding that would result from inadequate flute design at this diameter and length combination. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit setup.
For high-volume installations, this size is available in bulk pack quantities — see Milwaukee's complete SDS+ bit catalog for all available quantity options across the full range of diameters and lengths.
