Product Description
Milwaukee SHOCKWAVE Impact Duty Carbide Multi-Material Drill Bit, 1/2 in. x 10 in. x 12 in.
Model Number: 48-20-8893
The Milwaukee 48-20-8893 SHOCKWAVE Impact Duty Carbide Multi-Material Drill Bit is a professional general-purpose drill bit engineered for contractors, electricians, plumbers, HVAC technicians, mechanical contractors, and any tradesperson who needs a single bit capable of drilling cleanly through the full range of materials encountered on a typical jobsite. As a true multi-material bit, the 48-20-8893 drills cleanly through brick, block, concrete, steel, aluminum, ceramic tile, backerboard, wood, PVC, and drywall without requiring the operator to switch between dedicated masonry, wood, or metal bits as the drill encounters different layers or applications. The 1/2 in. bit diameter is the maximum size offered in Milwaukee's SHOCKWAVE Multi-Material lineup and accommodates the larger fastener sizes used for structural anchoring, conduit penetrations, and equipment mounting work. The 12 in. overall length with 10 in. working depth gives the operator the reach to drill deep through wall plates, joists, and stacked layers in one continuous pass.
The aggressive multi-grind carbide tip is the engineering at the heart of this bit's multi-material performance. The carbide geometry is designed to deliver up to 10 times longer life in stacked-material applications compared to standard installer bits, and up to 85 percent faster drilling speeds in metal compared to standard masonry bits, eliminating the need to keep separate dedicated bits for different layer types and reducing both bit inventory and installer time on the job. The carbide composition and tip grind are engineered for the high-impact, high-rotational-load environment of impact drivers and hammer drills, which is what the SHOCKWAVE Impact Duty branding signifies across Milwaukee's accessory lineup. Conventional twist drill bits typically shatter or strip in impact tools because they are designed for the smoother torque profile of a standard drill driver, while SHOCKWAVE Impact Duty bits are engineered specifically for the high-stress shock loading that impact drivers generate.
The 1/4 in. hex shank fits any standard impact driver, drill driver, or hammer drill chuck without modification, making the 48-20-8893 a true all-tool bit that one operator can move between platforms across a workday without bit swaps or chuck changes. Typical applications include anchor installation for shelving and equipment mounting, electrical conduit and outlet box penetrations, plumbing rough-in through framing and masonry, HVAC equipment installation, deck and fence post hardware, and any drilling application where the bit will encounter mixed materials in a single hole or across a project. The 48-20-8893 is part of Milwaukee's SHOCKWAVE Impact Duty Multi-Material Drill Bit family, which is available in smaller diameters from 5/32 in. through 3/8 in., plus a shorter 1/2 in. x 4 in. x 6 in. variant (48-20-8892), all sold separately. Multi-piece sets are also available, including the 5-piece 48-20-8898 (5/32 in., 3/16 in., 1/4 in., 5/16 in., 3/8 in.) and 7-piece 48-20-8899 (adds 1/8 in. and 1/2 in.) kits. Always operate the bit within the tool manufacturer's recommended RPM and impact ratings and wear appropriate PPE for the material being drilled, especially when drilling concrete, brick, or other dust-generating materials.
