Fischer SDS Plus Quattric II Drill Bit 12 mm

The Fischer SDS Plus Quattric II drill bit with a 12 mm diameter is a high-performance tool engineered for professional drilling in concrete, reinforced concrete, and masonry. Designed for use with SDS Plus hammer drills, this drill bit features a specialized four-cutter head geometry that ensures rapid dust removal and minimizes the risk of jamming when encountering steel reinforcement. Its robust construction provides exceptional durability and stability, making it a reliable choice for demanding construction and renovation projects where precision and efficiency are paramount.

Advantages

The primary advantage of this drill bit lies in its advanced Quattric II head design, which significantly improves drilling speed and hole accuracy compared to standard two-cutter bits. The symmetrical four-cutter geometry ensures that the bit remains centered during operation, resulting in perfectly round holes that are ideal for secure anchor installations. Furthermore, the high-quality carbide tip is firmly embedded to withstand high impact forces, while the optimized flute design facilitates efficient debris extraction, reducing heat buildup and extending the overall service life of the tool.

Suitable for

• Drilling into reinforced concrete
• Masonry and brickwork applications
• Installation of heavy-duty anchors
• Professional construction and renovation tasks

When it may not be suitable

This drill bit is specifically optimized for concrete and masonry materials and is not suitable for drilling into wood, metal, or ceramic tiles, as the hammer action and carbide tip geometry are not designed for these substrates. Additionally, it should not be used in drill machines that lack an SDS Plus chuck system.

Key specifications

• Diameter: 12 mm
• Working length: 400 mm
• Total length: 450 mm
• Shank type: SDS Plus
• Head geometry: Four-cutter carbide tip

How to use

To use the Fischer SDS Plus Quattric II drill bit, insert the shank into the SDS Plus chuck of your hammer drill until it clicks into place. Ensure the drill is set to the hammer-drilling mode. Position the tip of the bit against the marked spot on the concrete surface and apply steady, moderate pressure while maintaining a perpendicular angle. Allow the tool to perform the work, avoiding excessive force that could overheat the tip. Periodically retract the bit from the hole during deep drilling to clear out accumulated dust.

What to consider before purchase

• Verify the required hole diameter for your specific anchor or fastener
• Ensure your power tool is compatible with the SDS Plus shank system
• Check the required drilling depth to match the working length of the bit

Usage recommendations

For optimal performance and safety, always wear appropriate personal protective equipment, including safety goggles and hearing protection. If you encounter steel reinforcement during drilling, reduce the feed pressure to prevent damage to the carbide tip.
