Product Description

The Milwaukee Electric Tool Corp 48-20-9017 is a carbide-tipped hammer drill bit designed for drilling into masonry, concrete, and block. Part of the SHOCKWAVE Impact Duty line, this bit measures 5/16 inches in diameter with an overall length of 12 inches and a working length of 10 inches. The carbide tip is engineered to withstand the repeated impact cycles of rotary hammer and hammer drill operation. Sold as a pack of 3, it suits contractors and trades professionals who need reliable spares on the job. Licensed HVAC, plumbing, and electrical trades regularly use bits like this when penetrating concrete slabs, CMU walls, or foundation walls for pipe and conduit runs.

This bit is suited for residential and light commercial applications where masonry penetration is required. Typical install scenarios include drilling anchor holes, running conduit through block walls, or boring through concrete pads. The 5/16-inch diameter is commonly specified for sleeve anchors and conduit clamp fasteners. The 12-inch overall length provides the reach needed for thicker block or double-wythe masonry.
