Milwaukee 48-20-7477 SDS Plus 44 Magnum™ M/2™ Carbide 2-Cutter Rotary Hammer Drill Bit, 1/2" x 16" x 18"

Milwaukee 48-20-7477 SDS Plus 44 Magnum™ M/2™ Carbide 2-Cutter Rotary Hammer Drill Bit, 1/2" x 16" x 18"

The Milwaukee 48-20-7477 is an SDS Plus rotary hammer drill bit from the 44 Magnum™ M/2™ series, built with a carbide 2-cutter (2CT) head for fast, efficient drilling in concrete and masonry. Sized at 1/2" diameter with a 16" flute length and 18" overall length, this bit is designed for deep-hole drilling applications on commercial and residential jobsites. The SDS Plus shank allows quick insertion and removal from compatible rotary hammers, while the carbide 2-cutter geometry channels debris away from the bore for cleaner, more accurate holes. This bit is well suited for setting anchors, running fastener penetrations, and other masonry drilling tasks where consistent hole diameter and depth are critical.
