Product Description
Milwaukee SDS+ Bit 1 in. x 18 in.
Model Number: 48-20-7085
The Milwaukee 48-20-7085 is an SDS+ rotary hammer drill bit in 1 in. diameter with an 18 in. overall length — the maximum standard extended-reach configuration at the largest standard SDS+ bore for the deepest structural anchor embedments and thickest through-wall penetrations at the 1 in. diameter. Milwaukee 44 Magnum SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with optimized helical fluting for concrete drilling performance. The 18 in. overall length provides the reach for the thickest concrete foundation walls, multi-layer construction assemblies, and structural anchor embedments where engineering specifications call for maximum anchor depth at 1 in. diameter for critical structural connections demanding the highest available pull-out load ratings in heavy structural concrete.
At the 1 in. large bore and 18 in. overall length, Milwaukee's flute design must maintain effective concrete debris transport throughout the complete deep working depth — the combination of large bore chip volume and extended debris transport path requires precise flute pitch optimization for this diameter-length combination to prevent choking that would interrupt production drilling pace on critical structural installations. At 1 in. diameter and this extreme depth, the SDS Max platform provides higher impact energy delivery for the hardest high-strength commercial concrete conditions where SDS+ energy delivery may be insufficient for productive penetration rate. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for standard commercial concrete applications at this bore and depth.
See Milwaukee's complete 44 Magnum SDS+ and SDS Max catalog for all available 1 in. configurations at every available length.
