The Fischer 549934 SDS+ concrete drill bit is a professional-grade tool engineered for high-performance drilling in concrete, masonry, and stone. With a 12 mm diameter, this drill bit is designed to deliver precise, clean holes while maintaining structural integrity during intensive construction or renovation tasks. Its robust construction ensures durability and consistent results, making it a reliable choice for demanding professional applications.

Advantages

This drill bit features a specialized SDS+ shank design that allows for rapid tool changes and efficient power transmission from the rotary hammer to the drill tip. The high-quality material composition provides excellent resistance to wear and heat, ensuring a long service life even when working with hard materials. The geometry of the bit is optimized for effective dust removal, which prevents clogging and enhances drilling speed and precision.

Suitable for

• Drilling holes in reinforced concrete
• Masonry and brickwork installation
• Renovation and construction projects
• Mounting fixtures and anchors

When it may not be suitable

This drill bit is not intended for use with standard drill chucks, as it requires an SDS+ compatible rotary hammer system. It is also not suitable for drilling through metal, wood, or ceramic tiles, as the specialized tip geometry is specifically optimized for masonry materials.

Key specifications

• Diameter: 12 mm
• Shank type: SDS+
• Material compatibility: Concrete, masonry, stone
• Application: Rotary hammer drilling

How to use

Insert the drill bit into the SDS+ chuck of your rotary hammer until it clicks into place. Ensure the tool is securely locked before starting the motor. Position the tip of the bit against the marked surface and apply steady, moderate pressure while the hammer action is engaged. Allow the tool to do the work and avoid excessive force, which can lead to overheating or premature wear. Periodically retract the bit from the hole to clear out accumulated dust and debris.

What to consider before purchase

• Verify that your power tool is equipped with an SDS+ chuck system
• Ensure the 12 mm diameter matches the requirements of your anchors or fasteners
• Check the depth capacity of your project against the length of the drill bit

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating a rotary hammer. Ensure the material being drilled is properly supported and stable before beginning work.
