Fischer 504208 SDS Max Spiral Cutting Drill Bit 18 mm

The Fischer 504208 SDS Max spiral cutting drill bit is a professional-grade tool engineered for high-performance drilling in concrete and masonry. With an 18 mm diameter and a specialized SDS Max shank, this drill bit is designed to provide optimal power transmission when used with rotary hammers. Its robust construction and advanced spiral geometry ensure efficient debris removal and precise hole formation, making it a reliable choice for demanding construction and renovation projects.

Advantages

This drill bit offers exceptional durability due to its high-quality material composition, which withstands the intense mechanical stress encountered during heavy-duty drilling. The SDS Max shank design allows for a secure and stable connection with compatible rotary hammers, minimizing vibration and maximizing energy transfer to the drill tip. The optimized spiral design facilitates rapid dust extraction, which prevents overheating and prolongs the service life of the tool while ensuring consistent drilling speed.

Suitable for

• Drilling holes in reinforced concrete
• Working with solid masonry and brickwork
• Heavy-duty construction and renovation projects
• Installation of anchors and structural fixings

When it may not be suitable

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

Key specifications

• Diameter: 18 mm
• Shank type: SDS Max
• Application: Concrete and masonry
• Design: Spiral cutting geometry

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, mark the desired drilling position clearly. Apply steady, moderate pressure while the tool is running, allowing the drill bit to do the work. It is important to keep the drill perpendicular to the surface to ensure a clean and accurate hole. Periodically retract the bit during deep drilling to help clear accumulated dust from the hole.

What to consider before purchase

• Verify that your power tool is compatible with the SDS Max shank system.
• Ensure the 18 mm diameter meets the specific requirements of your anchors or fasteners.
• Check the maximum drilling depth capacity of your rotary hammer.

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating a rotary hammer. Regularly inspect the drill bit for signs of wear or damage to maintain drilling efficiency and safety.
