Product Description
Milwaukee SDS+ Bit 1/2 in. x 4 in. x 6 in.
Model Number: 48-20-7471
The Milwaukee 48-20-7471 is an SDS+ rotary hammer drill bit in 1/2 in. diameter with a 4 in. working length and 6 in. overall length — a medium-duty anchor drilling bit for the 1/2 in. diameter that is among the most commonly specified anchor hole sizes in light-to-medium structural and equipment mounting concrete applications. The 1/2 in. diameter accommodates 3/8 in. wedge anchors, 3/8 in. sleeve anchors, and 3/8 in. drop-in anchors across a wide range of light structural connections, conduit support installations, equipment mounting, and general concrete fastening where medium-duty load ratings are required. Milwaukee SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized flute geometry for efficient, consistent concrete drilling throughout the bit's service life — the vacuum-brazed carbide bond maintains tip retention under the combined rotational and impact forces of SDS+ rotary hammer drilling at this medium diameter.
The 6 in. overall length is the standard compact configuration for typical anchor embedment depths and slab penetrations where the required hole depth is within 4 in. and the 6 in. bit provides adequate reach without the handling challenges of longer extended-length bits in overhead and horizontal drilling positions. The compact length is advantageous for overhead ceiling anchor installations, horizontal wall anchor drilling near obstructions, and any confined-space drilling application where a shorter bit makes positioning and control easier. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammer chuck systems for quick bit changes during production drilling operations. For higher-volume anchor installations at this diameter, Milwaukee offers the 1/2 in. bit in 15-pack and 25-pack bulk quantities for reduced per-bit cost.
Extended length versions of the 1/2 in. SDS+ bit are available for through-wall penetrations and deep embedment requirements — see Milwaukee's complete SDS+ bit lineup for all available lengths at this diameter.
