Features and Benefits:�Asymmetrical carbide teeth for up to 20% faster drilling speeds�Centering bit for easy spot drilling�Designed for SDS-Plus rotary hammers�Drilling Depth of 2" Adapter and centering bit sold separately (48-20-3582)�Spiral core body design to minimize friction and increases dust removal�Two-piece design for maximum versatilityMilwaukee® SDS-Plus masonry core bits are ideal for drilling large holes in brick, block, and concrete with SDS-Plus rotary hammers. Asymmetrical Carbide teeth break up material more effectively resulting in up to 20% faster drilling speeds. Centering bits allow for easy alignment of the hole and precise spot drilling. The versatile two-piece design allows users to drill with several different core bit sizes using one adapter. The spiral core body design minimizes friction in the hole and aids in dust removal during the application. Core bits cut with the outer edge only, therefore the operator must remove the inner core continue drilling for holes deeper than 2 in.
