SDS-MAX 4CT MX4™ 1-1/4" X 18" X 23"

The Milwaukee SDS-MAX 4CT MX4™ 1-1/4" x 18" x 23" is a large-diameter, long-reach rotary hammer drill bit built for heavy-duty concrete and reinforced concrete drilling. This is a step into high-load drilling, where both diameter and depth demand maximum durability and stability.

Performance & Design

• Solid carbide 4-cutter head
  Provides up to 5× longer life in concrete with rebar and maintains cutting efficiency under heavy load
• 4-cutter geometry
  Prevents binding and lock-up when hitting rebar, improving control and reducing downtime
• Rebar guards
  Reinforce cutting edges for durability in hard aggregate and steel
• Centering tip
  Enables accurate hole starts and reduces walking
• Variable flute design
  Removes dust faster, reduces heat, and improves drilling speed and efficiency
• Wear mark indicator
  Shows when the bit no longer meets ANSI anchor tolerances
