Milwaukee 1-1/4" x 17" x 22" Spline 4-Cutter Rotary Hammer Drill Bit 48-20-4400

STRUCTURAL AGGREGATE DESTRUCTION

In the world of heavy civil infrastructure, hitting a structural rebar cage isn't a minor inconvenience—it's a test of your equipment's survival. This Milwaukee Spline 4-Cutter bit is engineered for the raw power of heavy-duty rotary hammers used in bridge decks, retaining walls, and industrial foundations. The symmetrical 4-cutter head prevents the violent binding and tool kickback that occurs when lesser bits encounter reinforced steel, ensuring you maintain a straight, concentric bore through the most stubborn high-PSI concrete on the jobsite.

• / Symmetrical 4-Cutter Tip: Delivers precise, round holes while preventing bit seizure when striking heavy-gauge rebar or structural steel.
• / Industrial Spline Shank: Optimized for high-energy impact transmission, ensuring every blow from your hammer is converted into maximum aggregate penetration.
• / High-Volume Dust Flutes: Engineered to evacuate massive amounts of debris rapidly, reducing friction and preventing thermal degradation in 17-inch deep drilling applications.
• / Precision Rebar Chamfers: Reinforced carbide edges provide extreme durability during high-cycle industrial anchoring and demolition work.
