PURE IMPACT FORCE DELIVERY

Optimizing your fleet's output requires more than just high-voltage batteries; it demands the right interface between the hammer's piston and the substrate. The Milwaukee 48-20-4052 spline bit is engineered specifically for older-generation and high-capacity rotary hammers that rely on a mechanical spline drive to ensure zero slip. By utilizing a precision-machined shank, this bit captures the full kinetic energy of the tool's striking mechanism, delivering it straight to the reinforced carbide tip for faster penetration through cured concrete and masonry.

• / Superior Spline Interface: Maximizes rotational torque transfer while minimizing energy loss during heavy impact cycles for peak productivity.
• / Sustained Carbide Integrity: The vacuum-brazed 2-cutter head maintains geometric precision even when encountering high-PSI aggregate and rebar.
• / Optimized Flute Geometry: Engineered for rapid dust evacuation, preventing heat buildup and parasitic drag on deep-hole applications.
• / Industrial-Grade Steel: Shot-peened and heat-treated to resist the extreme fatigue stresses of 2,500+ BPM demolition-grade rotary hammers.
