Powerful breakthrough in reinforced concrete

Practical benefits
  • Dependable Milwaukee drilling performance: The one-piece solid steel design ensures you transfer maximum hammer impact to drill clean 55 mm holes through dense masonry.
  • Precise centering without wandering: You start each hole with pinpoint accuracy because the 3-cutter centering tip keeps the head firmly locked in position.
  • Resilient rebar protection chamfers: Embedded carbide teeth with protective chamfers prevent tip damage and tooth breakage whenever you hit metal reinforcement.

In a nutshell

The right choise for

With the Milwaukee 4932492057 SDS-Max tct tunnel bit, you drill deep 55 mm penetrations through thick walls and heavy structures in a single pass. Its solid one-piece steel design measuring 990 mm eliminates the need for separate adapters or extensions, transferring maximum impact energy directly to the cutting face. The 3-cutter centering tip allows you to start drilling with pinpoint accuracy without wandering off target. When encountering reinforced concrete, integrated rebar chamfers protect the carbide teeth from breakage, while three large dust removal channels efficiently clear debris from deep holes in concrete and masonry.
