SDS Plus 4CT MX4™ 3/4" X 16" X 18"

The SDS Plus 4CT MX4™ 3/4" x 16" x 18" Drill Bit is a high-performance masonry bit engineered for demanding drilling in reinforced concrete, brick, and block applications where embedded rebar is common.

Built with Milwaukee’s MX4™ solid carbide 4-cutter head, this bit is designed for maximum durability and speed in tough aggregate. The four-cutter geometry helps maintain a round, accurate hole while significantly improving resistance when hitting rebar compared to standard 2-cutter bits.

Its breaker-point tip aggressively fractures concrete for faster penetration, while reinforced flutes efficiently remove dust and debris to reduce heat buildup and improve drilling speed. The longer body design provides added reach for deeper anchoring and structural applications without sacrificing stability.

The 3/4-inch diameter is commonly used for larger anchor installations, and the 16-inch usable length (18-inch overall length) makes it suitable for deep drilling through thick concrete walls, slabs, and structural members.

Key Features:

• MX4™ 4-cutter carbide head for superior rebar resistance
• Breaker-point tip for faster drilling into concrete
• Reinforced flute design for improved dust removal and reduced heat
• High durability for extended life in abrasive materials
• SDS-Plus shank compatible with all SDS-Plus rotary hammers
• Designed for deep-hole and structural drilling applications

Ideal Applications:

• Deep anchoring in concrete and masonry
• Drilling through reinforced concrete with rebar
• Structural mechanical, electrical, and plumbing installs
• Commercial construction and heavy-duty renovation work
