Milwaukee 1-3/8" x 17" x 22" Spline 4-Cutter Rotary Hammer Drill Bit 48-20-4410
STRUCTURAL CONCRETE PENETRATION POWER
When your crew is dealing with high-volume concrete drilling, the Milwaukee 48-20-4410 Spline 4-cutter bit represents the pinnacle of mechanical durability and fleet efficiency. Engineered specifically for heavy-duty rotary hammers, this bit eliminates the common point of failure—rebar lock-up—ensuring that your project stays on schedule and your tool motors stay protected from sudden torque spikes.
- / 4-Cutter 90° Geometry: Ensures precise, round holes while preventing the bit from binding or seizing when encountering rebar.
- / Patented Rebar Chamfers: Built-in reinforcement at the tip prevents carbide fracturing, significantly extending the service life of the bit.
- / High-Volume Dust Fluting: Optimized spiral geometry rapidly clears debris from deep holes, reducing friction and tool heat.
- / Spline Shank Interface: Provides a heavy-duty mechanical connection for maximum impact energy transfer from the tool to the substrate.
