Milwaukee SDS Plus 4-Cutter MX4 5/8" x 6" x 8" Drill Bit 48-20-7200

DOMINATE HARD AGGREGATE AND REBAR WITH MX4 TECHNOLOGY

When drilling into reinforced concrete, the transition from aggregate to steel is where most bits fail. The Milwaukee MX4™ SDS Plus 4-Cutter bit is engineered to handle these high-stress environments without binding or snapping. Featuring a solid head carbide design, this bit provides up to 5X longer life than standard cutters, ensuring that your cost-per-hole remains low over the life of the tool. The 4-cutter geometry is critical for preventing lock-ups when encountering rebar, allowing for a smooth, continuous bore that maintains the structural integrity of the hole. Furthermore, the variable flute design optimizes dust evacuation, which not only keeps the carbide cooler but also reduces the mechanical load on your rotary hammer, extending battery runtime by up to 20%.

• / Solid head carbide construction delivers up to 5x longer life in concrete with rebar compared to standard bits.
• / Integrated rebar guards provide maximum durability and prevent bit lock-up in hard aggregate.
• / Sharp centering tip allows for exact spot drilling and prevents bit walking on concrete or metal decking.
• / Variable flute geometry removes dust faster to reduce heat and deliver more holes per battery charge.
• / Built-in wear mark indicator shows when the bit no longer meets ANSI B212.15 requirements for anchor fitment.
