Milwaukee Tool 48-20-8086 Sds-plus Drill Bit 20mm

Product Description

The MILWAUKEE TOOL 48-20-8086 is a carbide-tipped rotary hammer drill bit designed for use with SDS-Plus rotary hammers. It features a spear-tip cutting shape and is constructed with a carbide-tipped high-speed steel body built to handle demanding concrete, masonry, and block applications. The bit measures 20mm in diameter with a usable flute length of 150mm and an overall length of 200mm. The SDS-Plus shank provides positive engagement with compatible rotary hammers, transmitting both rotation and percussion efficiently through the bit body. Licensed tradespeople and contractors who work with concrete anchors, through-bolts, and penetrations will find this a standard tool for daily production work.

This bit is suited for residential and commercial construction, mechanical, electrical, and plumbing rough-in work where concrete or masonry penetrations are required. Typical applications include drilling anchor holes for threaded rod, concrete screws, and expansion anchors in poured concrete, CMU block, and brick. The 20mm diameter makes it appropriate for medium-to-large anchor installations. It is installed and used by HVAC technicians, plumbers, electricians, and general contractors performing structural fastening and equipment mounting on masonry substrates.

Installation Notes

This bit is used by licensed tradespeople including HVAC mechanics, electricians, and plumbers performing concrete and masonry drilling. Always wear appropriate PPE including eye protection and hearing protection when operating a rotary hammer. Confirm the work area is clear of embedded conduit, rebar, or utilities before drilling. Allow the bit to do the work at steady, controlled feed pressure — excessive force can cause premature carbide tip failure.
