Milwaukee Introduces New MX4 Carbide Drill Bits

MILWAUKEE, WI - Milwaukee Electric Tool Corporation introduces new MX4 Carbide Drill Bits designed for extended life, durability, and accuracy in SDS+ rotary hammer drilling. Featuring 4-cutter solid carbide heads, the new line offers up to 3x longer life than competitors when drilling reinforced concrete.

With 90° cutter alignment, the MX4 line of bits resists locking up in rebar and offers more accurate hole dimensions for improved anchor engagement. By maximizing the interface where the carbide meets the steel, these bits offer durability against unintended rebar impacts.

The MX4 line also features four spiraled flutes for fast debris removal and impact durability. A centering tip ensures accurate hole placement and minimizes slipping.

Carbide drill bits undergo a great deal of stress when drilling a hole in concrete. The 4-cutter tip design on the MX4 product evenly distributes this workload and extends the life of the bit.
