Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit, 3/4"X10"X12"

The 48-20-7215 Milwaukee SDS MX4™ 4-Cutter Masonry Drill Bit is a premium SDS Plus rotary hammer bit engineered to deliver up to 5X longer life when drilling through concrete with rebar. Featuring a solid carbide 4-cutter head, this bit resists wear and prevents lock-up when encountering embedded rebar, helping reduce downtime and improve productivity. Its sharp centering tip ensures precise hole placement, while variable flute geometry clears dust faster to reduce heat buildup and deliver up to 20% more holes per battery charge. Built in Germany and designed to meet ANSI anchor specifications, it's ready for the toughest drilling jobs—because concrete is hard enough without your drill bit giving up first.
