Product Description
Milwaukee SDS+ Bit 11/16 in. x 8 in.
Model Number: 48-20-7058
The Milwaukee 48-20-7058 is an SDS+ rotary hammer drill bit in 11/16 in. diameter with an 8 in. overall length — a mid-size concrete drilling bit for anchor installations and penetrations at the 11/16 in. diameter specification in applications where the working depth requires more reach than the standard compact length provides. The 11/16 in. diameter accommodates a specific range of concrete anchors and fasteners that require this precise bore diameter rather than the adjacent standard 5/8 in. or 3/4 in. sizes, including specific wedge anchor, sleeve anchor, and through-bolt sizes specified by structural or mechanical engineers for particular load-rated applications. Milwaukee SDS+ bits incorporate carbide vacuum-brazed to heat-treated steel shanks using the vacuum brazing process that creates the metallurgical bond between carbide and steel required for positive tip retention under the sustained rotary hammer impact loads encountered in concrete drilling across the full service life of the bit.
The 8 in. overall length provides additional working depth beyond the standard 6 in. compact configuration — allowing anchor embedment depths beyond the 4 in. range that the standard bit reaches, accommodating longer concrete screw lengths that require deeper pilot holes, and providing through-wall capability in thin CMU construction where the standard 6 in. bit cannot complete the penetration from a single side. The optimized helical flute geometry maintains efficient concrete debris evacuation through the 8 in. working depth, preventing accumulation at the drill point that would slow penetration rate and cause binding. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammer chuck systems for fast bit changes during production drilling operations across anchor installation projects.
