Product Description
Milwaukee SDS+ Bit 7/32 in. x 4 in. x 6 in. — 25 Pack
Model Number: 48-20-7521
The Milwaukee 48-20-7521 is a 25-pack of SDS+ rotary hammer drill bits in 7/32 in. diameter with a 4 in. working length and 6 in. overall length — the 44 Magnum series bulk-pack format for high-volume small anchor and concrete fastener drilling at the 7/32 in. specification. Milwaukee's 44 Magnum SDS+ bits deliver the consistent production performance that commercial anchor installation requires across all 25 bits in the pack — the vacuum-brazed carbide tips, heat-treated steel shanks, dual cutting edges, and optimized flute geometry deliver predictable, reliable drilling speed and bit behavior from first bit to last throughout the bulk supply, which is essential for maintaining production pace on large-scale anchor installation projects where inconsistent bit behavior would disrupt workflow. The 25-pack per-bit cost reduction versus individual and 5-pack purchasing is substantial — the bulk format is the standard procurement approach for commercial electrical contractors, general contractors, and specialty installation crews who install large numbers of 7/32 in. anchors per project.
The 7/32 in. diameter is the standard pilot hole size for light-duty concrete screw anchors and small expansion fasteners used extensively throughout commercial construction for conduit support brackets, equipment anchoring, sign mounting, and general concrete fastener installations. The compact 4 in. overall length is well-suited to the typical 2-3 in. embedment depths of light-duty concrete anchors while providing adequate working length for overhead ceiling anchor installations and horizontal wall anchor drilling near obstructions where the short bit length enables the drill to be positioned closer to the work surface than longer configurations allow. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during continuous production anchor drilling operations.
Individual unit (48-20-7421) and 5-pack formats are also available for lower-volume or single-replacement purchasing needs.
