Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 5/8" x 15" x 21" 48-20-3922
REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY
When boring through high-PSI concrete reinforced with rebar, the mechanical failure of a standard bit is usually a matter of when, not if. The Milwaukee MX4 4-Cutter SDS Max bit is engineered to solve the primary point of failure: rebar lock-up. By utilizing a solid head carbide design rather than a simple brazed insert, this bit maintains structural integrity under extreme thermal loads. The 4-cutter geometry ensures that even when the bit encounters lateral resistance from steel reinforcement, it maintains a true path without the violent binding that typically shears off cutter heads or stalls the rotary hammer's internal clutch. For professionals running M18 FUEL or MX FUEL SDS Max hammers, the optimized flute geometry is a critical ROI factor, as it clears debris faster to reduce friction and heat, effectively delivering up to 15% more holes per battery charge.
- / Solid Head Carbide construction delivers up to 5x longer service life in heavy rebar applications compared to standard bits.
- / Integrated Rebar Guards protect the bit from catastrophic failure during high-torque aggregate encounters.
- / Sharp centering tip eliminates bit walk and ensures exact spot drilling for precision anchor placement.
- / Wear Mark Indicators provide a clear visual reference for ANSI B212.15 compliance, ensuring holes remain within tolerance for mechanical anchors.
- / High-efficiency flute design accelerates dust extraction, lowering operating temperatures and extending tool runtime.
