Description

Milwaukee's Spline 4-cutter rotary hammer drill bits are engineered for the raw power of heavy-duty rotary hammers used in bridge decks, industrial foundations, and retaining walls. Featuring a symmetrical 4-cutter tip geometry, this bit prevents violent binding and tool kickback when encountering reinforced steel, ensuring you maintain a straight, concentric bore through the most stubborn high-PSI concrete. This high-performance bit is designed for maximum material removal and extended service life in demanding masonry applications.
  • 4-Cutter 4 x 90 Tip Geometry
  • Patented Rebar Chamfers
  • High Volume Flute for Debris Removal
  • Industrial Spline Shank

Features

  • Symmetrical 4-cutter head delivers precise, round holes while preventing bit seizure when striking heavy-gauge rebar.
  • High-volume dust flutes are engineered to evacuate massive amounts of debris rapidly, reducing friction and thermal degradation.
  • Precision rebar chamfers provide increased carbide durability during high-cycle industrial anchoring and demolition work.
  • Rock carbide teeth and a specialized brazing formula optimize drilling for up to 20% longer life compared to standard bits.
