Milwaukee Spline Bit 4-Cutter 1-3/4″ x 23″

REINFORCED CONCRETE DOMINANCE

When you’re staring down a structural slab laced with rebar, you don’t have time for bits that bind or snap. The Milwaukee 48-20-4418 is engineered for the sheer survival of the heavy civil jobsite, utilizing a massive 1-3/4 inch 4-cutter head that maintains its geometry even under the brutal impact of a Spline-drive rotary hammer. This isn’t just about making a hole; it’s about maintaining high-production speeds in the most punishing aggregate environments on earth.

• / 4-CUTTER 90° GEOMETRY: Prevents the bit from locking up when encountering rebar, ensuring continuous drilling and operator safety.
• / PATENTED REBAR CHAMFERS: Reinforced cutting edges provide superior durability and prevent carbide breakdown during high-torque strikes.
• / HIGH-VOLUME DEBRIS FLUTE: Rapidly evacuates concrete dust to reduce heat buildup and maintain peak drilling RPM.
• / SPLINE SHANK COMPATIBILITY: Engineered for a precision fit in heavy-duty Spline-drive hammers for maximum energy transfer.
