2-units min. Milwaukee 48-20-3988 – 4-Cutter Rotary Hammer Drill Bit – SDS Max – 1-1/2 in - 48-20-3988

The MX4 4-Cutter SDS MAX Rotary Hammer Drill Bit features solid head carbide for up to 5x longer life in concrete with rebar. It includes rebar guards for maximum durability in hard aggregate and rebar. The sharp centering tip enables exact spot drilling in concrete and metal decking. The 4-cutter design prevents lock-up in rebar, reducing downtime. Variable flutes remove dust faster, reducing heat and delivering up to 15% more holes per battery charge. Breaker points pulverize material for up to 20% faster drilling speeds. Reinforced flutes avoid bit breakage, and wide flute entrances increase dust removal. The wear mark indicator shows when the bit no longer meets the ANSI requirement. It meets ANSI B212.15 to fit common anchors and is ideal for concrete with rebar and masonry applications. It fits all SDS-Max rotary hammers. The bit has a 1-1/2 in diameter, 18 in cutting depth, 23 in overall length, spiral flutes, 18 in flute length, 45/64 in SDS Max shank, centering point, right-hand cutting direction, and carbide cutting edge. Applicable materials include block, brick, concrete, and reinforced concrete. It is German made.
