REINFORCED STRUCTURAL CORE PENETRATION

When the project scope demands drilling through high-density reinforced aggregate and bridge decks, the Milwaukee MX4™ 4-Cutter SDS Max bits are the only choice for the heavy civil professional. These bits are engineered for sheer survival, utilizing a solid carbide head that won't shear off when it bites into structural rebar grids. Designed to handle the punishing impact of high-torque rotary hammers, this bit ensures that your crew maintains maximum productivity in the harshest drilling environments encountered on industrial infrastructure sites.

• / Solid Head Carbide: Delivers up to 5x longer service life in high-PSI concrete with dense rebar reinforcement.
• / Integrated Rebar Guards: Drastically reduces the risk of bit lock-up or tool kickback when hitting structural steel.
• / Precision Centering Tip: Eliminates bit-walk on metal decking and ensures anchor holes are placed with dead-nuts accuracy.
• / High-Volume Flute Geometry: Optimized for rapid dust evacuation, keeping the bit cool and maximizing holes per charge.
• / ANSI Wear Mark Indicator: Provides a critical visual gauge to ensure bits still meet code requirements for anchor installation.
