Product Description
Milwaukee SDS+ Bit 1/4 in. x 12 in. x 14 in.
Model Number: 48-20-7435
The Milwaukee 48-20-7435 is an SDS+ rotary hammer drill bit in 1/4 in. diameter with a 12 in. working length and 14 in. overall length — an extreme extended-reach configuration at the small 1/4 in. anchor diameter for the deepest CMU through-wall penetrations and the longest concrete screw anchor pilot holes where no shorter configuration provides adequate depth from the accessible drilling position. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized fluting for concrete drilling performance. At the small 1/4 in. bore and 12 in. working depth, Milwaukee specifically engineers the flute geometry for effective concrete debris transport from the extreme depth — the very limited flute cross-section of the 1/4 in. bore must handle chip evacuation over the longest standard working depth for this diameter, requiring the most precise flute pitch calibration in the 44 Magnum range.
The 14 in. overall length enables drilling through the thickest standard CMU block with finish material on both faces, the longest concrete screw anchor pilot holes for engineering-specified maximum pull-out load ratings, and positions where the drill body must be held substantially back from the drilling face due to ceiling, wall, or structural obstruction. This is the longest standard 1/4 in. SDS+ configuration for situations where even the 10 in. configuration falls short of the required depth. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers. For production-volume use, bulk pack formats provide significantly lower per-bit cost.
