Milwaukee SDS+ CORE masonry core bits are designed for efficient drilling of large holes in brick, block, and concrete using SDS Plus rotary hammers. Featuring asymmetrical carbide teeth, these bits break up material more effectively, enabling up to 20% faster drilling speeds. The centering bits provide easy alignment and precise spot drilling, while the versatile two-piece design allows users to work with multiple core bit sizes using a single adapter. The spiral core body reduces friction within the hole and helps remove dust during use. Core bits cut only with the outer edge, so the inner core must be removed to continue drilling holes deeper than 2 inches. Model Number: 48-20-5245
