Milwaukee SDS Plus 4CT MX4™ 9/16" X 16" X 18"

REINFORCED CONCRETE ENDURANCE

When your jobsite productivity hinges on high-volume hole consistency, the Milwaukee 48-20-7387 MX4 series represents the pinnacle of rotary hammer accessory engineering. This 9/16" bit is purpose-built for the commercial fleet operator where the cost-per-hole is the only metric that matters. Featuring a solid-head carbide construction, it doesn't just survive rebar strikes; it dominates them. The precision-engineered 4-cutter geometry prevents the dreaded lock-up that often snaps inferior bits and strains your tool's clutch, ensuring your SDS Plus hammers stay in the field and out of the tool crib for repairs.

• / Solid Head Carbide: Delivers up to 5X longer life in reinforced concrete and hard aggregate compared to standard tipped bits.
• / Anti-Lock 4-Cutter Geometry: Eliminates bit binding in rebar, reducing physical fatigue for the operator and protecting the internal gears of the hammer.
• / Variable Flute Design: Maximizes dust extraction to keep the head cool and optimize drilling speed by up to 20% per battery charge.
• / Wear Mark Indicator: Integrated visual gauge allows for rapid verification that the bit still meets ANSI B212.15 anchor installation standards.
• / Centering Tip: Provides dead-accurate hole placement by eliminating bit walking on smooth or uneven concrete surfaces.
