Milwaukee SDS Plus 4-Cutter MX4 3/16" x 6" x 8" Drill Bit 15 Pack 48-20-7912

REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY

When high-volume anchoring in reinforced concrete is the standard, the MX4™ 4-Cutter series represents the pinnacle of mechanical durability and drilling efficiency. These bits are engineered with a solid head carbide that maintains structural integrity through 5X more rebar encounters than standard bits. The 4-cutter geometry is critical for professional productivity; it prevents the bit from locking up upon hitting steel, protecting both the user from sudden torque reactions and the rotary hammer's internal clutch. By utilizing variable flutes, these bits evacuate debris with significantly higher efficiency, reducing thermal build-up and allowing cordless SDS Plus hammers to deliver up to 20% more holes per charge. For critical structural connections, the integrated wear mark indicator provides a definitive visual gauge to ensure every hole remains within ANSI B212.15 tolerances.

• / Solid Head Carbide: Delivers up to 5X longer life in concrete with rebar compared to standard 2-cutter bits.
• / Anti-Lock 4-Cutter Design: Prevents bit seizure in rebar, reducing downtime and tool strain during heavy-duty drilling.
• / Variable Flute Geometry: Optimizes dust extraction to keep the bit cool and maximize battery runtime for cordless users.
• / Wear Mark Indicator: Provides a visual reference for ANSI compliance, ensuring precise hole sizing for mechanical anchors.
