Milwaukee Spline Bit 4-Cutter 3/4″ x 16″

MAXIMUM REBAR REINFORCED DURABILITY

When your crew is penetrating reinforced concrete at scale, the mechanical integrity of your masonry consumables dictates the overhead of the entire project. The Milwaukee 48-20-4335 Spline Bit is engineered to solve the common failure point of rotary drilling—lock-up upon rebar contact. By utilizing a symmetrical 4-cutter 4 x 90° tip geometry, this bit maintains a consistent path, preventing the bit from seizing or wandering when hitting high-tensile steel reinforcement.

• / QUAD-EDGE SYMMETRY: The 4-cutter 4 x 90° geometry produces rounder holes for better anchor retention and prevents binding in rebar.
• / PATENTED REBAR CHAMFERS: Reinforced shoulders withstand the shock of steel impact, ensuring the carbide tip stays intact during heavy-duty cycles.
• / HIGH-VOLUME FLUTE DESIGN: Specialized spiral geometry accelerates dust and debris removal to reduce thermal load and increase drilling speed.
• / INDUSTRIAL SPLINE INTERFACE: Designed for high-output power transfer between the tool and the workpiece in heavy rotary hammer applications.
