Product Description
Milwaukee SDS+ Bit 1/4 in. x 8 in. x 10 in. — 25 Pack
Model Number: 48-20-7533
The Milwaukee 48-20-7533 is a 25-pack of 44 Magnum series SDS+ rotary hammer drill bits in 1/4 in. diameter with an 8 in. working length and 10 in. overall length — a bulk-pack format for the extended-length 1/4 in. SDS+ configuration for commercial anchor installation at production volume where the 10 in. overall length is required for through-wall CMU penetrations or longer concrete screw embedments. The 25-pack provides the production supply and per-bit cost economy for commercial installation crews who regularly drill 1/4 in. anchors requiring the extended depth of the 10 in. configuration — bulk purchasing at this length reduces per-bit cost significantly versus individual unit purchasing. Milwaukee's 44 Magnum series maintains consistent performance across all 25 bits through vacuum-brazed carbide tips, heat-treated steel shanks, and optimized fluting engineered for effective small-bore debris evacuation through the 8 in. working depth.
The 10 in. overall length extends the reach of the compact 6 in. configuration for through-wall drilling in standard CMU block plus finish material, longer concrete screw anchor embedments where pull-out ratings require deeper pilot holes, and drilling positions where surrounding structure forces the hammer back from the wall. At 1/4 in. diameter and 8 in. working depth, Milwaukee's flute pitch and geometry optimization for this specific combination maintains effective concrete debris transport through the full depth without choking that would interrupt production drilling pace. The SDS+ shank provides tool-free engagement in all SDS+ rotary hammers for fast bit changes throughout production operations.
Individual unit (48-20-7438 uses 20 in. OAL — for 10 in. individual unit, see catalog) and standard compact 25-pack available — see Milwaukee's complete 44 Magnum SDS+ catalog for all configurations at the 1/4 in. diameter.
