Milwaukee SDS+ CORE masonry core bits are designed for drilling large holes in brick, block, and concrete using SDS Plus rotary hammers. Featuring asymmetrical carbide teeth, these core bits break up material more efficiently, delivering up to 20% faster drilling speeds. The centering bits ensure easy hole 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 design reduces friction and helps remove dust during drilling. These core bits cut only with the outer edge, so operators need to remove the inner core to continue drilling holes deeper than 2 inches. Model Number: 48-20-5210
