The Fischer 531761 masonry drill bit is a high-performance tool engineered for precision drilling in demanding materials. With a diameter of 5.5 mm, this drill bit is specifically optimized for use with rotary hammers, ensuring consistent results when working with stone, brick, and concrete. Its robust construction is designed to withstand the stresses of intensive drilling, making it a dependable choice for both professional construction sites and residential renovation projects.

Advantages

This drill bit features a high-quality design that promotes efficient material removal and reduces vibration during operation. The geometry of the bit is crafted to maintain stability and accuracy, which helps in achieving clean, precise holes every time. Its durable composition ensures a long service life, even when subjected to the repetitive impact forces typical of rotary hammer drilling, providing excellent value and reliability for various masonry applications.

Suitable for

• Drilling into solid brick and masonry walls
• Creating holes in concrete surfaces for anchors or fixings
• General construction and renovation tasks
• Professional installation work requiring precise hole diameters

When it may not be suitable

This drill bit is not intended for use on metal, wood, or ceramic tiles, as the tip geometry is specifically optimized for masonry materials. It is also not suitable for use with standard drills that lack a hammer function, as it requires the impact action of a rotary hammer to perform effectively.

Key specifications

• Diameter: 5.5 mm
• Compatibility: Rotary hammers
• Material application: Concrete, brick, and stone

How to use

To use the drill bit, insert it securely into the chuck of your rotary hammer, ensuring it is locked in place according to the tool manufacturer's instructions. Mark the desired drilling location clearly before starting. Begin drilling at a low speed to establish the hole position, then increase to the recommended operating speed. Maintain steady, moderate pressure and allow the tool to perform the work, ensuring the bit remains perpendicular to the surface to prevent binding or deviation.

What to consider before purchase

• Verify the required hole diameter for your specific anchors or fasteners
• Ensure your power tool is compatible with the SDS+ or relevant shank system
• Check the depth capacity required for your specific project

Usage recommendations

Always wear appropriate personal protective equipment, including safety glasses and hearing protection, when operating power tools. Regularly clear dust from the hole during deep drilling to prevent overheating and ensure optimal performance.
