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, delivering up to 20% faster drilling speeds. The centering bits ensure easy alignment and precise spot drilling, while the versatile two-piece design allows for use with several different core bit sizes through one adapter. The spiral core body reduces friction and helps remove dust during drilling. These core bits cut with the outer edge only, requiring the operator to remove the inner core to continue drilling holes deeper than 2 inches. Model Number: 48-20-5235
