The Milwaukee 48-20-5432 is a professional-grade one-piece SDS-MAX core bit designed for drilling large-diameter holes in concrete, brick, and block. It features a 4-inch cutting diameter and an 11-3/8-inch overall length with a 3-inch drilling depth. The bit is engineered with asymmetrical alternating carbide teeth to pulverize material up to 20% faster than standard bits. Its thick-wall core body ensures durability when used with high-powered rotary hammers, while the fluted exterior minimizes friction and accelerates debris removal. This unit is compatible with centering bit 48-20-5495 for precise hole placement
