Product Description
Milwaukee SDS+ Bit 3/16 in. x 4 in. x 6 in. — 25 Pack
Model Number: 48-20-7511
The Milwaukee 48-20-7511 is a 25-pack of 44 Magnum series SDS+ rotary hammer drill bits in 3/16 in. diameter with a 4 in. working length and 6 in. overall length — the standard compact bulk-pack format for the 3/16 in. anchor drilling diameter used throughout commercial construction for light-duty concrete screw anchors and small expansion fasteners. Milwaukee's 44 Magnum series delivers consistent production performance across all 25 bits through vacuum-brazed carbide tips on heat-treated steel shanks, dual cutting edges, and optimized helical flute geometry engineered for reliable concrete drilling throughout the bit's service life from the first bit to the last in the pack. The 25-pack provides the production supply and per-bit cost economy needed for commercial installation crews who install large quantities of 3/16 in. anchors per project — the bulk format's per-bit cost reduction versus individual and 5-pack purchasing makes it the standard procurement approach for sustained anchor installation work at this diameter.
The compact 6 in. overall length is ideally suited to typical light-duty anchor embedment depths and the overhead and confined-space drilling applications that characterize small anchor installation throughout commercial construction — ceiling conduit support brackets, wall-mounted equipment, and light structural fastening that represent the core 3/16 in. anchor use case. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during continuous production drilling. Milwaukee's manufacturing consistency across the 25-pack ensures predictable drilling speed and bit behavior throughout the full supply — important for maintaining production pace on commercial anchor installation projects where inconsistent bit performance would disrupt workflow and slow installation pace.
Individual unit (48-20-7412) available for single-bit replacement — see Milwaukee's complete 44 Magnum SDS+ catalog for all pack quantities at the 3/16 in. diameter.
