Product Description
The Milwaukee 48-20-3936 SDS-Max MX4 Rotary Hammer Drill Bit is a heavy-duty drilling accessory designed for deep drilling applications in concrete, reinforced concrete, brick, and masonry. It features Milwaukee’s MX4 solid-carbide 4-cutter head, which provides significantly longer life and reliable drilling performance when working through hard aggregate and embedded rebar.
The 4-cutter carbide head prevents the bit from binding when it hits rebar, reducing downtime and improving durability in demanding job-site conditions. A precision centering tip ensures accurate hole placement and easier hole starts on hard surfaces.
Its extra-long design allows drilling through thick walls, deep anchor holes, or multiple structural layers. The variable flute geometry removes debris efficiently, helping maintain drilling speed while reducing heat buildup during extended use.
