Milwaukee 48-20-9013 Carbide Hammer Drill Bit 1/4x18 Inches

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 48-20-9013 is a SHOCKWAVE Impact Duty carbide hammer drill bit designed for demanding masonry and concrete drilling applications. Built with a carbide tip, it delivers the hardness needed to penetrate concrete, block, and masonry without premature wear. The bit measures 1/4 inch in diameter with a 16-inch working length and an 18-inch overall length, giving trades access to deep anchoring and through-hole applications where standard-length bits fall short. It is sold as a unit of one bit and is suited for licensed contractors, concrete tradespeople, and experienced installers working with rotary hammer drills in the field.

This hammer drill bit is used in residential and commercial construction and renovation where concrete, brick, or block materials require accurate, clean holes. Typical applications include anchor bolt installation, conduit penetrations, and mechanical fastening into structural masonry. The 18-inch overall length makes it particularly useful for penetrating thick walls or reaching deep-set anchor points that shorter bits cannot reach.
