MAXIMIZE UPTIME IN REINFORCED CONCRETE

When your crew is drilling high-volume anchor holes or through-penetrations in heavily reinforced concrete, the mechanical failure of a bit is the fastest way to kill productivity. The Milwaukee MX4™ SDS MAX 4-Cutter bit is engineered to solve the "lock-up" issue common with standard 2-cutter designs. By utilizing a solid carbide head with integrated rebar guards, this bit doesn't just survive rebar hits—it maintains its geometry to ensure consistent hole diameters required for critical structural anchors. The optimized flute geometry is a key factor in thermal management, pulling dust away from the head to prevent the heat-cycling that leads to premature carbide failure and reduced battery runtime on cordless platforms.

• / Solid Head Carbide construction delivers up to 5x longer life in high-PSI concrete and rebar-heavy slabs.
• / Integrated Rebar Guards protect the bit from shattering or binding when encountering structural steel.
• / Sharp Centering Tip eliminates bit walk, providing exact spot drilling for precision layout in concrete and metal decking.
• / 4-Cutter Design prevents the bit from seizing in rebar, reducing the risk of tool kickback and downtime.
• / Wear Mark Indicators provide a clear visual gauge to ensure every hole meets ANSI B212.15 tolerances for anchor security.
