Product Description
Milwaukee SDS+ Bit 1/4 in. x 10 in. x 12 in. — 25 Pack
Model Number: 48-20-7534
The Milwaukee 48-20-7534 is a 25-pack of 44 Magnum series SDS+ rotary hammer drill bits in 1/4 in. diameter with a 10 in. working length and 12 in. overall length — the bulk-pack format for the extended-length 1/4 in. SDS+ configuration for commercial anchor installation projects where the 12 in. overall length is required for through-wall CMU penetrations or longer concrete screw embedments at production volume. The 25-pack provides the production drilling supply and per-bit cost economy for commercial installation crews who regularly install 1/4 in. anchors requiring the extended depth of the 12 in. configuration — the bulk format's per-bit cost reduction versus individual and smaller-pack purchasing makes it the economical standard for sustained anchor installation work at this diameter and length. Milwaukee's 44 Magnum series maintains consistent drilling performance across all 25 bits through vacuum-brazed carbide tips, heat-treated steel shanks, and optimized fluting engineered for the specific challenge of 1/4 in. small-bore drilling at 10 in. working depth.
The 12 in. overall length extends the working reach of the standard 6 in. 1/4 in. SDS+ configuration for through-wall drilling in standard CMU block construction where the additional wall thickness plus any finish material depth exceeds the standard bit's working length, and for concrete screw anchor installations where longer embedment depth specifications require greater pilot hole depth than the standard bit provides. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes during continuous production drilling operations on commercial projects. Milwaukee's manufacturing consistency across all 25 bits in the pack ensures predictable drilling speed and bit behavior throughout the full supply.
Individual unit (48-20-7434) available for single-bit needs — see Milwaukee's complete 44 Magnum SDS+ catalog for all available formats at this diameter and length.
