Product Description
Milwaukee SDS+ Bit 1/4 in. x 8 in. x 10 in.
Model Number: 48-20-7433
The Milwaukee 48-20-7433 is an SDS+ rotary hammer drill bit in 1/4 in. diameter with an 8 in. working length and 10 in. overall length — an individual extended-length unit for the 1/4 in. anchor diameter for through-wall CMU penetrations and deeper anchor embedments requiring more working depth than the compact 6 in. overall configuration. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized helical fluting for concrete drilling performance. At the small 1/4 in. bore and 8 in. working depth, Milwaukee specifically calibrates the flute geometry to maintain effective concrete debris transport from the deep hole base to the surface without choking — the small flute cross-section must handle debris transport over the full extended depth.
The 10 in. overall length enables through-wall drilling in standard CMU block with light finish material, longer concrete screw anchor pilot holes where pull-out load specifications require greater embedment depth, and drilling positions where surrounding structure prevents the hammer from being placed close to the face. The individual unit format is appropriate for single-bit replacement or lower-volume use of the extended configuration. For production-volume anchor drilling at this diameter and length, the 25-pack (48-20-7533) provides significantly lower per-bit cost. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during production operations.
