Milwaukee SDS MAX 4-Cutter Masonry Drill Bit, 1"X12"X17"

Milwaukee SDS MAX 4-Cutter Masonry Drill Bit, 1"X12"X17"

The Milwaukee 48-20-3953 SDS MAX 4-Cutter Masonry Drill Bit is a heavy-duty drilling solution built for serious concrete work, especially when rebar tries to ruin your day. With a solid carbide head and 4-cutter design, this bit delivers up to 5X longer life and prevents lock-ups when hitting rebar. The sharp centering tip ensures accurate starts, while variable flutes clear dust quickly to reduce heat and improve efficiency—meaning more holes per charge and fewer excuses to stop.
