SDS Plus 4CT MX4™ 3/4" X 6" X 8"

The SDS Plus 4CT MX4™ 3/4" x 6" x 8" Drill Bit is a high-performance rotary hammer bit engineered for demanding drilling in concrete, block, brick, and reinforced materials with embedded rebar.

Built with Milwaukee’s MX4™ 4-cutter solid carbide head, this bit delivers superior durability and impact resistance compared to standard 2-cutter designs. The four-cutter geometry helps maintain a round, precise hole while reducing binding when encountering rebar, improving both speed and tool life.

Its breaker-point tip aggressively fractures concrete for faster penetration, while the optimized flute design efficiently clears dust and debris to reduce heat buildup and maintain consistent drilling performance. Reinforced flutes add strength and help minimize vibration under heavy load.

The 3/4-inch diameter is ideal for larger anchor applications, and the 6-inch usable length (8-inch overall length) provides controlled depth for structural drilling in concrete and masonry.

Key Features:

• MX4™ 4-cutter carbide head for maximum durability in rebar
• Breaker-point tip for faster, more aggressive drilling
• Reinforced flute design for reduced vibration and longer life
• Efficient debris removal for cooler operation and higher productivity
• SDS-Plus shank compatible with all SDS-Plus rotary hammers
• Optimized for reinforced concrete applications

Ideal Applications:

• Drilling anchor holes in concrete and masonry
• Working through rebar in reinforced slabs and walls
• Electrical, plumbing, and mechanical installations
• Commercial and residential construction projects
