Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 5/8" x 16" x 21" 48-20-3918

Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 5/8" x 16" x 21" 48-20-3918

MAXIMIZE UPTIME IN REINFORCED CONCRETE

When your crew is drilling deep anchors in high-PSI concrete, the last thing you can afford is a bit lock-up when hitting rebar. The Milwaukee MX4™ 4-Cutter SDS Max Rotary Hammer Drill Bit is engineered specifically for the most demanding structural applications. Featuring a solid head carbide design, these bits deliver up to 5x longer life compared to standard cutters. The integrated rebar guards act as a mechanical shield, preventing the bit from binding or snapping when encountering steel reinforcement. For the professional contractor, this means less downtime and a significantly higher return on investment per bit.

  • / Solid Head Carbide construction provides extreme durability and up to 5x longer life in concrete with rebar.
  • / Sharp centering tip ensures exact spot drilling, preventing bit walk on smooth surfaces or metal decking.
  • / Optimized flute geometry removes dust faster, reducing friction-induced heat and delivering up to 15% more holes per battery charge.
  • / Wear Mark Indicators provide a clear visual cue when the bit no longer meets ANSI requirements for anchor fitment.
