Cheville à visser Fischer 90681

The Fischer fixing set for diamond drills FDBB (Screw Anchor Fischer 90681) is intended for temporary fastening of diamond and core drilling devices and diamond saws. The set includes a reusable spindle bolt with nut and washer and an expansion element that remains in the drill hole after dismantling. The detachable screw connection between the expansion element and the spindle allows the spindle bolt to be removed and reused by reattaching a new expansion element.

Advantages

The reusable spindle bolt reduces material waste and lowers replacement costs. The detachable connection simplifies dismantling without removing the expansion element from the drill hole, which speeds up maintenance and reuse. The set is compatible with standard diamond drilling equipment and provides a stable temporary fastening for core drilling and sawing operations.

Suitable for

• Temporary fixing of diamond core drilling rigs
• Mounting of diamond saws for cutting operations
• Situations where the spindle bolt needs to be reused
