Product Description
Milwaukee SDS+ Bit 5/8 in. x 22 in. x 24 in.
Model Number: 48-20-7609
The Milwaukee 48-20-7609 is an SDS+ rotary hammer drill bit in 5/8 in. diameter with a 22 in. working length and 24 in. overall length — the longest standard configuration in the 5/8 in. SDS+ bit range, designed for the deepest-reach anchor installations, extended through-penetration drilling, and structural drilling applications where the 24 in. overall length provides working reach that no other standard SDS+ bit length achieves at this diameter. The 5/8 in. diameter is a heavily specified anchor size for structural connections requiring 1/2 in. wedge anchors, sleeve anchors, and adhesive anchor systems, and the 24 in. length extends the application range to include drilling through extra-thick concrete sections, making penetrations through concrete walls with additional insulation, finish material, or structural thickness beyond standard CMU dimensions, and completing deep slab anchor installations where structural engineers specify embedment depths that exceed what shorter bits can reach.
At 22 in. working depth, flute engineering is the dominant performance factor — Milwaukee's helical flute geometry at this length and diameter must move pulverized concrete through a 22 in. column of concrete dust and fragments to evacuate it at the hole opening, requiring precise flute pitch, volume, and surface finish to maintain continuous debris flow without the packing and choking that would halt drilling progress and require the operator to clear the hole repeatedly. Milwaukee engineers the flute specification for this extended-length bit to maintain effective debris evacuation throughout the full 22 in. working depth, enabling continuous drilling without hole-clearing interruptions. The SDS+ shank engages all SDS+ rotary hammers tool-free for quick setup. This is an extended-reach specialty bit — standard structural anchor work at 5/8 in. uses the 12 in. or 18 in. length configurations that fit most commercial applications.
