Fischer SDS Plus Quattric II Drill Bit 8 mm x 265 mm

The Fischer SDS Plus Quattric II drill bit, measuring 8 mm in diameter and 265 mm in total length, is a high-performance drilling tool engineered for demanding applications in masonry and concrete. Designed for compatibility with rotary hammers featuring an SDS Plus chuck system, this drill bit utilizes a four-cutter head geometry that ensures rapid material removal and precise hole drilling. Its robust construction is optimized for longevity, providing consistent performance even when encountering reinforced concrete or hard stone surfaces.

Advantages

The primary benefit of the Quattric II design is its advanced carbide tip, which minimizes vibration and prevents the bit from snagging on steel reinforcement. This design feature significantly increases the service life of the tool while maintaining high drilling speeds. The optimized flute geometry efficiently transports dust away from the cutting zone, reducing heat buildup and preventing clogging during deep hole drilling. Users benefit from increased accuracy and reduced physical strain, as the bit maintains a stable trajectory throughout the drilling process.

Suitable for

• Drilling holes for heavy-duty anchors in concrete
• Installation of electrical conduits and piping in masonry
• Professional construction and renovation projects
• Drilling into reinforced concrete structures

When it may not be suitable

This drill bit is specifically designed for rotary hammers with an SDS Plus interface and is not compatible with standard drill chucks found on conventional impact drills. It is also not intended for drilling into wood, metal, or ceramic tiles, as the aggressive carbide head geometry may cause damage to these materials.

Key specifications

• Diameter: 8 mm
• Total length: 265 mm
• Working length: 200 mm
• Shank type: SDS Plus
• Head design: Four-cutter carbide tip

How to use

Insert the drill bit into the SDS Plus chuck of your rotary hammer until it clicks into place. Ensure the tool is set to the hammer-drill mode for optimal performance in concrete. Apply steady, moderate pressure while allowing the tool to perform the work. Periodically retract the bit from the hole during deep drilling to clear accumulated dust, which helps maintain drilling speed and prevents the bit from overheating.

What to consider before purchase

• Verify that your power tool supports the SDS Plus connection system
• Check the required hole depth to ensure the 200 mm working length is sufficient
• Ensure the 8 mm diameter matches the specifications of the anchors or fasteners being used

Usage recommendations

Always wear appropriate personal protective equipment, including safety goggles and hearing protection, when operating rotary hammers. Inspect the drill bit for signs of wear or carbide tip damage before each use to ensure safety and precision.
