Product Description
Milwaukee SDS+ Bit 3/16 in. x 12 in. x 14 in.
Model Number: 48-20-7415
The Milwaukee 48-20-7415 is an SDS+ rotary hammer drill bit in 3/16 in. diameter with a 12 in. working length and 14 in. overall length — a deep extended-length configuration for the 3/16 in. anchor diameter for through-wall penetrations and deep embedment applications requiring more working depth than the standard 12 in. overall configurations provide. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized helical fluting specifically calibrated for small-bore deep drilling — at 3/16 in. diameter and 12 in. working length, the limited flute cross-section must transport concrete debris continuously from deep in the hole through the full depth without choking, requiring precise flute pitch and geometry optimization that Milwaukee engineers for this specific configuration. The 14 in. overall length provides reach for thick masonry construction, through-penetrations where multiple material layers combine to exceed 12 in. overall configuration reach, and drilling positions where surrounding structure prevents placing the hammer close to the work surface.
The 3/16 in. diameter is the standard pilot hole for light-duty concrete screw anchors and small expansion fasteners throughout commercial construction. At the 14 in. overall length, this configuration is a specialty bit for the specific applications where both the 3/16 in. small bore and the deep working length are both required simultaneously — most 3/16 in. anchor installations are well served by shorter configurations, and the 14 in. is specified for the deepest requirements at this diameter. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production drilling operations.
