SDS Plus 4CT MX4™ 3/8" X 10" X 12"

The Milwaukee 48-20-7361 SDS Plus 4CT MX4™ 3/8" x 10" x 12" Drill Bit is a professional-grade rotary hammer bit designed for deep, high-performance drilling in concrete, brick, block, and reinforced concrete with embedded rebar.

Built with Milwaukee’s MX4™ solid carbide 4-cutter head, this bit delivers excellent durability and stability in demanding materials. The four-cutter geometry improves hole precision, reduces walking, and enhances performance when encountering rebar compared to traditional two-cutter designs.

A breaker-point tip aggressively fractures concrete for faster penetration, while the reinforced flute design efficiently removes dust and debris to reduce heat buildup and maintain consistent drilling speed. The extended body design provides added reach for deep anchoring and structural applications.

The 3/8-inch diameter is ideal for medium-duty anchor installations, and the 10-inch usable depth (12-inch overall length) makes it suitable for deep drilling through thick slabs, walls, and structural concrete.

Key Features:

• MX4™ 4-cutter carbide head for superior durability in rebar
• Breaker-point tip for fast, aggressive drilling
• Reinforced flutes for improved debris removal and reduced vibration
• Extended length for deep-hole drilling applications
• SDS-Plus shank compatible with all SDS-Plus rotary hammers
• Designed for reinforced concrete and masonry

Ideal Applications:

• Deep anchor installations in concrete and block
• Drilling through reinforced concrete with rebar
• Electrical, plumbing, and mechanical installations
• Commercial and structural construction work
