MAXIMUM REBAR REINFORCEMENT DOMINANCE
When your crew is boring through high-PSI concrete and hitting unexpected rebar strikes, the Milwaukee 48-20-4345 Spline 4-Cutter bit is the only insurance policy you need for your rotary hammer fleet. Engineered with a precision 4 x 90° tip geometry, this bit eliminates the catastrophic lock-up typically associated with hitting steel reinforcement, ensuring consistent uptime on the most demanding commercial jobsites.
- / QUAD-EDGE SYMMETRY: The 4-cutter head distributes the impact energy more evenly, preventing seizing and providing a cleaner, rounder hole for critical anchor placements.
- / PATENTED REBAR CHAMFERS: Advanced geometry at the tip prevents the edges from chipping or shattering when encountering rebar, drastically extending the service life of the bit.
- / HIGH-VOLUME FLUTE DESIGN: Optimizes dust extraction to reduce heat buildup and frictional drag, keeping your tool running cooler and your drilling speeds higher.
- / SPLINE SHANK COMPATIBILITY: Designed specifically for heavy-duty Spline drive rotary hammers to maximize torque transfer and impact force.
