Milwaukee 7/8" x 10" x 12" SDS Plus MX4 4-Cutter Drill Bit 48-20-7230

MAXIMIZED CONCRETE PENETRATION EFFICIENCY

When your crew is burning through standard bits in high-psi concrete, the Milwaukee MX4™ series isn't just an option—it's a requirement for maintaining project timelines. These bits are engineered for the high-volume contractor who measures performance in cost-per-hole. The solid head carbide construction withstands the extreme thermal friction generated during deep-depth drilling, ensuring the 48-20-7230 doesn't tap out when it hits structural rebar, keeping your rotary hammer fleet moving at peak productivity.

• / Solid Head Carbide construction delivers up to 5X longer life in rebar-reinforced concrete versus standard 2-cutter bits.
• / Integrated Rebar Guards protect the bit from catastrophic failure, preventing lock-ups when hitting structural steel.
• / Precision Centering Tip eliminates bit walking for exact hole placement, critical for structural anchor layouts.
• / Enhanced Flute Geometry accelerates dust evacuation, reducing internal friction and increasing holes per battery charge.
• / Wear Mark Indicator provides a visual gauge for ANSI B212.15 compliance, ensuring proper seat for mechanical anchors.
