Product Description
Milwaukee SDS+ Bit 3/4 in. x 12 in.
Model Number: 48-20-7065
The Milwaukee 48-20-7065 is an SDS+ rotary hammer drill bit in 3/4 in. diameter with a 12 in. overall length — a large-diameter, extended-length concrete drilling bit for heavy-duty structural anchor installations, through-wall conduit penetrations in standard CMU construction, and deep embedment drilling applications requiring the combination of large diameter and extended reach. The 3/4 in. diameter is the anchor drilling size for large-diameter structural anchors including 5/8 in. wedge anchors, 5/8 in. sleeve anchors, and large-diameter adhesive and epoxy anchor systems used in structural steel base plate connections, equipment mounting pads, overhead structure attachments, and heavy mechanical equipment anchoring where elevated working load ratings are required by engineering specifications. Milwaukee SDS+ bits are manufactured with carbide cutting tips vacuum-brazed to heat-treated alloy steel shanks — at 3/4 in. diameter, the carbide tip mass and vacuum-brazed bond area provide the cutting durability needed for the sustained high-energy rotary hammer drilling that large-diameter concrete anchor installation requires across an extended working depth.
The 12 in. overall length provides the working reach for complete through-penetrations in standard 8 in. and 10 in. CMU block walls, for anchor placements in foundation walls, grade beams, and thick concrete structures where embedment depth requirements exceed what standard-length bits can reach, and for conduit sleeve drilling through concrete walls where the full wall thickness must be penetrated in a single drill setup. At 3/4 in. diameter and 12 in. length, efficient flute performance is essential — Milwaukee's spiral flute geometry at this size and depth combination maintains continuous concrete debris evacuation from the base of the hole through the full working depth, preventing the hole packing and energy waste that occurs when pulverized concrete cannot escape the hole efficiently. The SDS+ shank engages all SDS+ rotary hammer chuck systems tool-free for quick bit changes during production drilling of multiple same-size holes on anchor installation projects.
Available in 15-pack bulk packaging for anchor installation contractors and crews who consistently drill 3/4 in. holes in large quantities and benefit from reduced per-bit purchasing cost compared to individual unit pricing.
