Milwaukee 48-20-7451 Sds Plus Rotary Hammer Drill Bit, 3/8 X 6 In.

The Milwaukee 48-20-7451 is a professional-grade SDS Plus rotary hammer drill bit engineered for fast, efficient drilling in concrete and masonry. Featuring Milwaukee's M/2™ 2-cutter technology, this bit delivers up to 20% more holes per charge in cordless rotary hammers compared to standard bits, while maintaining exceptional durability in both corded and cordless applications. The breaker point design pulverizes material more effectively, resulting in faster drilling speeds.

The enhanced rebar guards protect the bit when striking embedded steel, while the reinforced variable flute geometry maximizes chip extraction for longer bit life and better performance.

Features and Benefits

• SDS Plus Shank: Locks firmly into compatible rotary hammers for consistent, reliable performance without slipping.
