Product Description
Milwaukee SDS+ Bit 3/4 in. x 18 in.
Model Number: 48-20-7066
The Milwaukee 48-20-7066 is an SDS+ rotary hammer drill bit in 3/4 in. diameter with an 18 in. overall length — a long-reach configuration at the largest standard SDS+ anchor diameter for through-wall penetrations in thick structural concrete sections and deep anchor embedments. The 18 in. overall length provides the working depth for drilling through thick concrete walls, multi-layer construction assemblies, and structural anchor installations where engineering specifications require extended embedment depth at the 3/4 in. diameter for critical structural connections. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized helical fluting — at 3/4 in. diameter and 18 in. length, the flute design must maintain effective concrete debris evacuation throughout the full working depth without choking that would interrupt production drilling pace on structural anchor installations.
The 3/4 in. diameter is used for large structural anchors in the highest load-rated wedge anchor, sleeve anchor, and adhesive anchor systems for critical structural connections in commercial and industrial construction where maximum anchor pull-out ratings are specified. At 18 in. overall length, this configuration addresses applications requiring deep embedment or through-wall capability at 3/4 in. diameter beyond what the standard and intermediate-length configurations can reach. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers — for the very hardest high-strength commercial concrete conditions at this large diameter, the SDS Max platform provides higher impact energy delivery for demanding heavy concrete drilling.
See Milwaukee's complete 44 Magnum SDS+ catalog for all available 3/4 in. configurations, and the SDS Max lineup for maximum energy delivery in the hardest conditions.
