Milwaukee SDS Max 4CT MX4™ 1-7/16" X 18" X 23"

REINFORCED CONCRETE PENETRATION POWER

When you're drilling into bridge footings or high-PSI structural columns, hitting rebar isn't just an obstacle; it's a certainty that eats through lesser bits. The Milwaukee MX4™ 4-Cutter SDS Max drill bits are built to survive the high-heat, high-impact environments of heavy civil job sites, utilizing a solid-head carbide construction that maintains structural integrity where others shatter. These aren't just accessories; they are critical consumables engineered for the raw torque of 18V and 72V rotary hammer platforms.

• / SOLID HEAD CARBIDE: Engineered for maximum durability in high-strength concrete and heavy rebar encounters, outlasting standard tipped bits by 5X.
• / 4-CUTTER GEOMETRY: Ensures precise, perfectly round holes to meet mission-critical structural anchoring compliance and prevent fastener failure.
• / REBAR GUARD: Optimized tip geometry prevents locking or binding upon impact with steel reinforcement, significantly reducing kickback and operator fatigue.
• / ENHANCED FLUTE DESIGN: Rapidly ejects dust and abrasive slurry to minimize heat friction, keeping the bit cool during continuous deep-hole drilling.
• / ANSI WEAR INDICATOR: Integrated visual reference ensures your holes stay within the strict tolerances required by ANSI B212.15 for mechanical anchors.
