Milwaukee SDS Plus 4-Cutter MX4™ 3/8" x 16" x 18" Drill Bit 48-20-7357

DOMINATE REBAR AND HARD AGGREGATE WITH MX4 DURABILITY

The Milwaukee MX4™ SDS Plus 4-Cutter drill bits represent a significant advancement in mechanical design for high-cycle anchoring applications. Engineered for the professional who demands maximum ROI from their consumables, these bits feature a solid head carbide construction that maintains structural integrity even when encountering heavy rebar. The 4-cutter geometry is specifically designed to prevent the bit from locking up or binding upon impact with steel reinforcement, significantly reducing the risk of tool kickback and downtime. By utilizing variable flute geometry, these bits optimize dust evacuation, which directly translates to lower operating temperatures and a 20% increase in holes per battery charge—a critical metric for high-volume cordless rotary hammer users.

• / Solid head carbide delivers up to 5X longer life in concrete with rebar compared to standard 2-cutter bits.
• / Integrated rebar guards provide maximum durability in hard aggregate, preventing head failure during high-torque drilling.
• / Sharp centering tip ensures exact spot drilling, preventing bit walk on concrete and metal decking for precise anchor placement.
• / Wear mark indicator provides a clear visual cue for end-of-life, ensuring all drilled holes continue to meet strict ANSI B212.15 requirements.
