STRUCTURAL REBAR PENETRATION DOMINANCE
When you're boring into bridge decks or structural footings, hitting Grade 60 rebar isn't a possibility—it is a guarantee. The Milwaukee MX4™ 4-Cutter SDS Max bits are engineered for the brutal reality of heavy civil infrastructure, featuring a solid carbide head that refuses to yield when the aggregate gets aggressive. This isn't just a consumable; it's a precision-machined solution for maintaining hole concentricity and ensuring every mechanical anchor sets to spec without the downtime of bit lock-up or thermal failure.
- / SOLID HEAD CARBIDE: Delivers up to 5X longer life in high-PSI concrete with embedded structural steel.
- / INTEGRATED REBAR GUARDS: Maximum durability design prevents the bit from shattering upon contact with rebar.
- / SHARP CENTERING TIP: Enables exact spot drilling on metal decking and hard aggregate without bit walk.
- / VARIABLE FLUTE GEOMETRY: Clears dust and debris at high velocity to increase drilling speed and holes-per-charge by 15%.
- / WEAR MARK INDICATOR: Provides immediate visual confirmation that the bit still meets ANSI B212.15 inspection requirements.
