## Long description

The Fischer 531839 masonry drill bit is a high-performance tool specifically engineered for use with rotary hammers. With a diameter of 18 mm, this drill bit is designed to deliver consistent results when working with demanding materials such as concrete, solid brick, and natural stone. Its robust construction ensures longevity and stability during intensive drilling operations, making it a reliable choice for both professional construction sites and demanding renovation projects.
Advantages
This drill bit features a specialized design that optimizes the transfer of impact energy from the rotary hammer directly to the material, resulting in faster drilling progress and reduced wear on the tool. The high-quality material composition provides excellent resistance to heat and mechanical stress, ensuring that the bit maintains its structural integrity even during prolonged use. Its precise geometry allows for accurate hole placement and clean drilling results, which is essential for secure anchor installations and structural work.
Suitable for
Drilling into reinforced and non-reinforced concrete
Creating holes in solid brick and masonry
Working with natural stone and dense building materials
Professional construction and renovation tasks
When it may not be suitable
This drill bit is not intended for use with standard impact drills that lack a pneumatic hammer mechanism, as it requires the specific action of a rotary hammer to function effectively. It is also not suitable for drilling into metal, wood, or soft materials like drywall, as the aggressive cutting head design may cause damage or imprecise results in these substrates.
Key specifications
Diameter: 18 mm
Compatibility: Rotary hammers
Material suitability: Concrete, brick, stone
How to use
To use the drill bit, insert it securely into the SDS-plus chuck of your rotary hammer until it clicks into place. Ensure the tool is set to the hammer-drilling mode. Position the tip of the bit against the marked surface and apply steady, moderate pressure while keeping the drill perpendicular to the material. Allow the hammer mechanism to do the work, and periodically retract the bit from the hole to clear out accumulated dust and debris, which helps prevent overheating and binding.
What to consider before purchase
Verify that your rotary hammer supports the SDS-plus shank system
Ensure the 18 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 drill bit is cool to the touch before handling it immediately after use, as it can reach high temperatures during operation.
