Milwaukee SDS Plus 4-Cutter MX4 3/8" x 10" x 12" Drill Bit 10 Pack 48-20-7954

REBAR-READY PRECISION FOR HIGH-VOLUME CONCRETE ANCHORING

The MX4™ series represents a significant advancement in rotary hammer bit geometry, specifically engineered to solve the primary failure point in concrete drilling: rebar strikes. By utilizing a solid head carbide design rather than a simple brazed insert, these bits maintain structural integrity under extreme thermal loads. The 4-cutter geometry is critical for professional users as it prevents the bit from binding or "locking up" when encountering structural steel, a common cause of both tool damage and operator fatigue. Furthermore, the variable flute design optimizes the evacuation of masonry dust, reducing friction and allowing cordless SDS Plus hammers to deliver up to 20% more holes per battery charge, maximizing jobsite ROI.

• / Solid head carbide construction delivers up to 5X longer life in reinforced concrete applications.
• / Integrated rebar guards provide maximum durability in hard aggregate by protecting the tip during steel impact.
• / Sharp centering tip allows for exact spot drilling, preventing bit walk on smooth concrete or metal decking.
• / Variable flute geometry accelerates dust removal to reduce heat buildup and extend the life of the cutting edge.
• / Wear mark indicator provides a clear visual gauge to ensure holes remain within ANSI B212.15 tolerances for anchor setting.
