Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3970

ELITE REBAR-READY DRILLING CAPACITY

When your job site productivity depends on high-volume anchoring in reinforced concrete, the Milwaukee MX4 4-Cutter SDS Max Rotary Hammer Drill Bit delivers the fleet-level ROI you require. Engineered for the professional who cannot afford bit failure when hitting heavy rebar, this German-made bit utilizes a solid head carbide construction that maintains structural integrity long after standard two-cutter bits have failed. By significantly reducing the heat generated during deep-bore applications, these bits ensure your rotary hammer fleet spends more time drilling and less time in the cooling rack, providing a measurable increase in holes-per-charge performance.

• / SOLID HEAD CARBIDE: Provides up to 5x longer life in high-PSI concrete with heavy rebar reinforcement compared to standard bits.
• / 4-CUTTER DESIGN: Prevents the bit from locking up or binding when encountering rebar, protecting both the operator and the tool gearbox.
• / SHARP CENTERING TIP: Eliminates bit walking on smooth surfaces and metal decking, ensuring precise hole placement for critical structural layout.
• / INTEGRATED WEAR MARKS: Provides an immediate visual indicator for ANSI compliance, ensuring your anchors are always set in properly sized bores.
• / OPTIMIZED FLUTE GEOMETRY: Rapidly evacuates debris from the hole to reduce thermal build-up and improve drilling speed by up to 15%.
