Fischer 531846 SDS+ Masonry Drill Bit 20 mm

The Fischer 531846 SDS+ masonry drill bit is a professional-grade tool engineered for high-performance drilling in demanding materials. With a diameter of 20 mm, this drill bit is specifically designed to be used with rotary hammers equipped with an SDS+ chuck system, ensuring a secure fit and efficient power transmission during operation. Its robust construction allows for consistent results when working with concrete, stone, and various masonry substrates, making it an essential component for construction and renovation projects.

Advantages

This drill bit offers exceptional durability and resistance to wear, which is critical for maintaining performance over extended periods of heavy use. The SDS+ shank design facilitates quick and tool-free bit changes, significantly improving workflow efficiency on the job site. Furthermore, the geometry of the bit is optimized to ensure rapid dust removal from the borehole, which prevents overheating and contributes to a longer service life while maintaining high drilling precision.

Suitable for

• Drilling into reinforced and non-reinforced concrete
• Creating holes in natural stone and masonry
• Construction and renovation drilling tasks
• Professional installation work requiring precise 20 mm diameter holes

When it may not be suitable

This drill bit is not intended for use with standard drill chucks that do not support the SDS+ system. It is also not suitable for drilling into metal, wood, or ceramic tiles, as the design is specifically optimized for masonry and concrete applications.

Key specifications

• Diameter: 20 mm
• Shank type: SDS+
• Material compatibility: Concrete, stone, masonry
• Design: Professional-grade masonry drill bit

How to use

To use the drill bit, insert the SDS+ shank into the chuck of your rotary hammer until it clicks into place, ensuring it is securely locked. Before starting, ensure the hammer is set to the appropriate drilling mode. Apply steady, moderate pressure while the tool is running, allowing the bit to perform the cutting 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 binding.

What to consider before purchase

• Verify that your power tool is compatible with the SDS+ shank system
• Ensure the 20 mm diameter meets the specific 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 secured to prevent movement during the process.
