Fischer 504225 SDS Max Spiral Cutting Drill Bit 22 mm

The Fischer 504225 SDS Max spiral cutting drill bit is a professional-grade tool engineered for high-performance drilling in concrete and masonry. With a diameter of 22 mm, this robust drill bit is designed to withstand the rigorous demands of heavy-duty construction and renovation projects. Its specialized spiral geometry ensures efficient dust and debris removal, allowing for faster drilling progress and increased precision when working with rotary hammers.

Advantages

This drill bit offers exceptional durability and longevity due to its high-quality construction, which is specifically optimized for use with SDS Max power tools. The advanced spiral design minimizes friction and heat buildup during operation, which significantly extends the service life of the bit. Furthermore, the precise tip geometry ensures accurate hole starting and consistent performance, reducing the risk of bit wandering even when drilling into reinforced concrete or dense masonry materials.

Suitable for

• Drilling holes for heavy-duty anchors in concrete
• Installation of structural steel components
• Renovation work involving hard masonry
• Professional construction and infrastructure projects

When it may not be suitable

This drill bit is not suitable for use with standard drill chucks, as it requires an SDS Max connection system. It is also not intended for drilling into wood, metal, or soft materials, as the aggressive cutting geometry is specifically optimized for mineral-based building materials.

Key specifications

• Diameter: 22 mm
• Connection type: SDS Max
• Material compatibility: Concrete, masonry, reinforced concrete
• Design: Spiral cutting geometry for debris removal

How to use

Insert the drill bit into the SDS Max chuck of your rotary hammer until it clicks into place, ensuring it is securely locked. Before starting, ensure the hammer drill is set to the appropriate drilling mode. Position the tip of the bit at the desired location and apply steady, moderate pressure while the tool is running. Allow the spiral design to clear the debris from the hole automatically. Avoid excessive side pressure to prevent bit breakage or hole deviation.

What to consider before purchase

• Verify that your power tool is compatible with the SDS Max shank system
• Ensure the 22 mm diameter meets the requirements of your specific anchor or installation task
• Check the required drilling depth for your project

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating rotary hammers. Regularly inspect the drill bit for signs of wear or damage to ensure optimal performance and safety.
