Milwaukee SDS+ Core Bit, 4" X 2"

Milwaukee SDS+ Core Bit, 4" X 2"

The Milwaukee 48-20-5245 SDS+ Masonry Core Bit (4" x 2") is a large-hole core bit for masonry drilling in brick, block, and concrete using SDS-Plus rotary hammers. It features asymmetrical carbide teeth for up to 20% faster drilling speeds, a spiral core body to reduce friction and improve dust removal, and a two-piece design that lets you use multiple core bit sizes with a single adapter. Because core bits cut on the outer edge only, the inner core must be removed to continue drilling for holes deeper than 2".
