Milwaukee Tool 48-20-8083 Sds-plus Drill Bit 18mm

Product Description

The MILWAUKEE TOOL 48-20-8083 is an 18mm carbide-tipped rotary hammer drill bit with an SDS-Plus shank, designed for use in SDS-Plus rotary hammers on demanding drilling applications in concrete, masonry, and similar hard materials. The spear cutting shape and carbide-tipped construction are engineered to handle high-impact rotary hammer action without premature wear. With a usable flute length of 400mm (approximately 15.75 inches) and an overall length of 450mm (approximately 17.72 inches), this bit reaches depth in structural and foundation work where shorter bits fall short. It is installed and used by concrete trades, electricians, plumbers, and HVAC techs needing to penetrate masonry for anchors, conduit, and pipe penetrations.

This bit is suited for residential and commercial applications where SDS-Plus rotary hammers are the standard tool of choice. Typical uses include drilling anchor holes in poured concrete, block, and brick, as well as creating penetrations for conduit sleeves, pipe stubs, and structural fastener installations. The extended overall length makes it especially practical for deep-set anchor work and through-wall penetrations in thick masonry assemblies.
