MILWAUKEE SDS Plus MX4 Drill Bit 22x450mm

The MILWAUKEE SDS Plus MX4 drill bit, measuring 22mm in diameter and 450mm in length, is a high-performance tool engineered for demanding drilling tasks in concrete, reinforced concrete, and masonry. Featuring a robust 4-cutter head geometry, this drill bit ensures rapid material removal and consistent performance, even when encountering steel reinforcement. The reinforced core design enhances structural integrity, minimizing vibration and maximizing the lifespan of the tool during intensive professional use.

Advantages

The primary benefit of the MX4 design is its superior durability and efficiency in hard materials. The 4-cutter geometry prevents the bit from jamming when hitting rebar, which significantly reduces downtime and increases productivity on the job site. Furthermore, the optimized flute design facilitates efficient dust extraction, keeping the hole clean and preventing overheating during prolonged drilling operations. The high-quality carbide tip ensures precision and resistance to wear, making it a reliable choice for heavy-duty construction projects.

Suitable for

• Drilling into reinforced concrete
• Masonry and brickwork applications
• Professional construction and renovation projects
• Installation of heavy-duty anchors and fixings

This drill bit may not be suitable for drilling into soft materials like wood or metal, as the SDS Plus shank and carbide tip geometry are specifically optimized for impact-drilling in mineral-based substrates. It is also not intended for use in standard drill chucks without an SDS Plus adapter.

Key specifications

• Diameter: 22mm
• Total length: 450mm
• Shank type: SDS Plus
• Head geometry: 4-cutter carbide tip
• Material compatibility: Concrete, reinforced concrete, masonry

To use this drill bit, ensure your rotary hammer drill is set to the hammer-drill mode. Insert the bit into the SDS Plus chuck until it clicks into place. Apply steady, consistent pressure while drilling, allowing the tool to perform the work. Periodically retract the bit from the hole during deep drilling to clear out accumulated dust and debris, which helps maintain drilling speed and prevents the bit from overheating.

What to consider before purchase

• Verify that your power tool is compatible with the SDS Plus shank system.
• Ensure the 22mm diameter meets the specific requirements of your anchors or fasteners.
• Check the 450mm length to ensure it provides sufficient reach for your intended wall or floor thickness.

Always wear appropriate personal protective equipment, including safety glasses and hearing protection, when operating a rotary hammer drill. Ensure the drill bit is cool to the touch before handling it immediately after use.
