Product Description
Milwaukee SDS+ Bit 3/16 in. x 6 in. x 8 in. — 25 Pack
Model Number: 48-20-7512
The Milwaukee 48-20-7512 is a 25-pack of SDS+ rotary hammer drill bits in 3/16 in. diameter with a 6 in. working length and 8 in. overall length — the bulk-quantity format for high-volume small-diameter anchor drilling where the 3/16 in. diameter, 8 in. overall length combination and 25-unit pack quantity provide the production bit supply and per-bit cost efficiency needed for commercial anchor installation work. The 3/16 in. diameter is the standard pilot hole size for common concrete screw anchors, light-duty concrete fasteners, and small expansion anchors used throughout commercial construction for conduit support brackets, sign mounting, equipment anchoring, and general concrete fastener installations in floors, walls, and ceilings. Milwaukee SDS+ bits feature carbide vacuum-brazed to heat-treated steel shanks with dual cutting edges and optimized helical flute geometry for consistent concrete drilling performance across all 25 bits in the pack — manufacturing consistency across the pack ensures predictable drilling speed and bit behavior throughout the batch for production installation operations.
The 8 in. overall length provides the additional working depth compared to the standard 6 in. configuration — accommodating deeper anchor embedment requirements, longer concrete screw lengths, and through-wall penetrations in thin CMU construction that exceed what the 6 in. bit can reach. At 3/16 in. diameter, the 8 in. length extension requires precise flute engineering to maintain effective concrete debris evacuation through the additional depth, and Milwaukee's helical flute geometry is specifically designed for this at small diameters to keep hole debris moving continuously from the base of the hole to the surface throughout the drilling operation. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammer chuck systems for the fast bit changes needed during high-production anchor installation runs. The 25-pack format reduces per-bit cost significantly versus smaller pack quantities, making it the standard procurement approach for commercial concrete anchor installation crews.
For single-bit replacement, this size is available in individual packaging — see Milwaukee's complete SDS+ bit catalog for all available diameters, lengths, and pack quantities.
