Product Description
Milwaukee SDS+ Bit 5/8 in. x 10 in. x 12 in.
Model Number: 48-20-7604
The Milwaukee 48-20-7604 is an SDS+ rotary hammer drill bit in 5/8 in. diameter with a 10 in. working length and 12 in. overall length — a larger-diameter extended-length SDS+ concrete bit for medium-to-heavy structural anchor installations, through-wall conduit penetrations, and through-slab drilling applications in commercial and industrial concrete construction. The 5/8 in. diameter is one of the most heavily used anchor drilling sizes in structural concrete work, covering the pilot hole requirements for 1/2 in. wedge anchors, 1/2 in. sleeve anchors, 1/2 in. drop-in anchors, and 1/2 in. epoxy anchor systems commonly specified for structural steel connections, overhead equipment mounting, unistrut and conduit support systems, and heavy mechanical equipment anchoring where elevated load ratings are required. Milwaukee SDS+ bits are built with carbide cutting tips vacuum-brazed to heat-treated steel shanks using a manufacturing process that creates a metallurgical bond strong enough to maintain positive carbide retention through the sustained high-energy impacts generated by professional SDS+ rotary hammers during production anchor drilling in hard commercial concrete.
The 12 in. overall length provides the working reach essential for through-penetration drilling in standard 8 in. and 10 in. CMU block walls, for anchor installations in thick concrete foundations and mat slabs requiring embedment depths that exceed what standard-length bits can achieve, and for core-through penetrations in structural concrete walls where conduit must pass completely through the wall section. Milwaukee's spiral flute engineering for extended-length bits of this diameter is specifically optimized to maintain efficient debris evacuation through the full 10 in. working depth — the flute geometry and pitch are designed to move pulverized concrete aggregate efficiently from the bottom of the hole upward and out of the hole opening without the choking, packing, and binding that undermines cutting efficiency and bit life in extended-length concrete drilling with inferior flute designs.
Available in 15-pack bulk packaging for concrete anchor installation contractors who consistently install 1/2 in. anchors on commercial projects and benefit from the cost reduction of bulk purchasing over individual unit pricing.
