Milwaukee Spline Bit 4-Cutter 1″ x 22″

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.
