Product Description
Milwaukee SDS Max 4-Cutter 5/8 in. x 54 in. x 60 in.
Model Number: 48-20-3923
The Milwaukee 48-20-3923 is an SDS Max rotary hammer drill bit in 5/8 in. diameter with a 54 in. working length and 60 in. overall length — an extreme extended-reach configuration with Milwaukee's four-cutter carbide tip for the deepest structural penetrations and longest anchor embedments in the SDS Max platform at the 5/8 in. diameter. The four-cutter tip delivers four active carbide cutting contacts per revolution for faster penetration and extended bit life by distributing carbide wear across doubled surface area versus the standard two-cutter. At 60 in. overall length, this is among the longest standard SDS Max bit configurations available — serving the applications where extreme wall thickness, deep structural assemblies, or maximum anchor embedment depth requirements create the need for this unusual bit length that exceeds all standard shorter configurations' working depth.
The flute geometry for this extreme length must maintain effective concrete debris transport from the full 54 in. working depth — requiring precise pitch calibration to prevent the chip packing at this extreme depth that would interrupt production drilling pace on the critical structural applications this configuration addresses. The 5/8 in. diameter at 60 in. overall length addresses specific engineering-specified anchor installations where both the 5/8 in. bore and the maximum depth are simultaneously required in critical structural concrete work. Note: Due to this item's extreme length, shipping options may be limited — contact us before ordering for shipping details.
See Milwaukee's complete SDS Max four-cutter catalog for all available 5/8 in. configurations and for all extreme-length options in the SDS Max platform.
