Milwaukee SDS Plus 4-Cutter MX4 5/8" x 10" x 12" Drill Bit 48-20-7203

MAXIMUM DURABILITY FOR REINFORCED CONCRETE APPLICATIONS

High-performance masonry drilling requires more than just raw power; it demands accessories engineered to survive the friction and impact of rebar strikes. The MX4™ 5/8" x 10" x 12" SDS Plus bit utilizes a solid head carbide design that maintains structural integrity where standard bits fail. By incorporating rebar guards and a 4-cutter geometry, this bit eliminates the common lock-up scenario that causes jobsite downtime and potential tool kickback. The variable flute geometry is a critical mechanical upgrade, optimizing dust extraction to prevent heat buildup, which directly extends the runtime of cordless rotary hammers by reducing the load on the motor. For professionals requiring consistent anchor fitment, the integrated wear mark indicator ensures every hole meets ANSI B212.15 standards throughout the life of the bit.

• / Solid head carbide construction provides up to 5X longer life when encountering rebar compared to standard bits.
• / 4-Cutter geometry prevents binding and lock-up in hard aggregate for smoother, safer drilling operations.
• / Variable flute design accelerates dust removal, delivering up to 20% more holes per battery charge.
• / Sharp centering tip ensures exact spot drilling, preventing bit walk on concrete and metal decking.
• / Wear mark indicator provides a visual gauge for ANSI compliance and anchor fitment accuracy.
