Features and Benefits:�Designed for SDS-Plus rotary hammers�Threaded shank design for easy core bit removal�Two-piece design for maximum versatility�Works with SDS Plus Masonry Core BitsMilwaukee® 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 putter edge only, therefore the operator must remove the inner core continue drilling for holes deeper than 3 in.
