## Long description

The MILWAUKEE MX4 SDS Max drill bit is a professional-grade accessory engineered for high-performance drilling in concrete and masonry. With a 20 mm diameter and a total length of 520 mm, this tool is designed to withstand the rigors of heavy-duty construction tasks. The advanced MX4 geometry provides exceptional durability and ensures efficient dust removal, which helps maintain drilling speed and extends the life of the bit even when working with reinforced concrete.
Advantages
The primary benefit of this drill bit lies in its robust construction and specialized head design. The MX4 geometry minimizes vibration and heat buildup, allowing for smoother operation and reduced wear on both the tool and the drill bit itself. Its efficient flute design facilitates rapid debris evacuation, preventing clogging and ensuring consistent performance during deep drilling operations. This reliability makes it an essential component for professionals who require precision and longevity in demanding environments.
Suitable for
Drilling into reinforced concrete
Masonry and brickwork applications
Heavy-duty construction and renovation projects
Installation of large anchors and structural fixings
This drill bit may not be suitable for drilling into soft materials like wood or metal, as the SDS Max shank and carbide tip geometry are specifically optimized for hard mineral substrates. It is also not intended for use with standard rotary drills that lack the SDS Max chuck system.
Key specifications
Diameter: 20 mm
Working length: 400 mm
Total length: 520 mm
Shank type: SDS Max
Material compatibility: Concrete, reinforced concrete, masonry
To use the drill bit, ensure that your hammer drill is set to the appropriate mode for rotary hammering. Insert the SDS Max shank into the chuck until it clicks into place, ensuring a secure connection. Apply steady, consistent pressure during the drilling process, allowing the tool to do the work without forcing it, which helps preserve the integrity of the carbide tip.
What to consider before purchase
Verify that your power tool is compatible with the SDS Max shank system
Ensure the 20 mm diameter meets the requirements of your specific anchor or application
Check that the 400 mm working length is sufficient for your intended drilling depth
Usage recommendations: Always wear appropriate personal protective equipment, including eye and ear protection, when operating hammer drills. Periodically check the drill bit for signs of excessive wear or damage to the carbide tip to ensure safe and efficient operation.
