Milwaukee 1" x 17" x 22" Spline 4-Cutter Rotary Hammer Drill Bit 48-20-4375
REINFORCED CONCRETE DOMINANCE
When maintaining fleet productivity is the priority, the Milwaukee 48-20-4375 Spline 4-Cutter bit is the mechanical solution for high-cycle masonry applications. Engineered to withstand the sudden torque spikes of rebar encounters, this bit utilizes a symmetrical 4-cutter head that prevents binding and ensures a perfectly round hole for critical anchoring. For the fleet manager, this translates to significantly reduced bit-replacement costs and less strain on your rotary hammer's internal drivetrain during heavy-duty commercial drilling.
- / 4-Cutter Geometry: Prevents the bit from locking or wandering when striking rebar, ensuring maximum safety and tool longevity.
- / Wear-Resistant Rebar Chamfers: Strategic tip reinforcements increase durability during high-impact drilling in reinforced concrete.
- / Enhanced Flute Extraction: High-volume fluting rapidly clears dust and debris to maintain speed and reduce heat-related friction.
- / Precision Spline Shank: Optimized for universal compatibility with all Spline-drive rotary hammers, ensuring consistent energy transfer.
