Festool 768018 Diamond Disc, Multi‑Colour

The Festool 768018 Diamond Disc is a high‑performance abrasive tool designed for precision grinding and finishing on a wide range of hard materials. With its multi‑colour construction, the disc delivers exceptional durability, consistent wear characteristics, and superior edge retention, making it an ideal choice for professionals who demand reliability and efficiency in every cut.

Key Technical Specifications

• Diameter: 130 mm (Ø 130 mm)
• Inner Diameter: 25 mm (Ø 25 mm) – compatible with standard Festool and other brand routers, sanders, and grinders that accept a 25 mm core.
• Core Size: 22.2 mm – the inner hole is precisely machined to ensure a secure fit and optimal heat dissipation during operation.
• Manufacturer Number: 768018
• Colour Coding: Multi‑colour (typically green, blue, or red) indicating specific grit ranges for different applications.
• Material Composition: Premium diamond abrasive bonded with a high‑strength matrix to resist wear and maintain sharpness over extended use.

Performance Highlights

The Festool 768018 Diamond Disc is engineered for maximum efficiency on demanding surfaces such as concrete, stone, tile, ceramic, and metal. Its multi‑colour design allows users to select the appropriate grit level for each task:

• Green discs – coarse grits for rapid material removal.
• Blue discs – medium grits for shaping and smoothing.
• Red discs – fine grits for finishing and polishing.

Each colour variant maintains consistent performance across the entire disc, ensuring even wear and a uniform finish. The diamond particles are evenly distributed throughout the matrix, providing a stable cutting edge that resists chipping and dulling.

Applications Across Industries

• Construction & Renovation: Ideal for grinding fresh concrete slabs, removing old mortar, or preparing surfaces for new flooring installations.
• Tile & Ceramic Work: Efficiently cuts and smooths ceramic tiles, porcelain, and glass tiles without generating excessive dust.
• Metal Fabrication: Suitable for grinding steel, aluminum, and other hard metals where precision and edge retention are critical.
• Stone & Marble Finishing: Delivers a clean, polished surface on natural stone, marble, and granite with minimal vibration.

Compatibility and Mounting

The disc’s inner diameter of 25 mm makes it compatible with a wide range of Festool routers, sanders, and grinders that accept a standard 25 mm core. The precise 22.2 mm core size ensures a snug fit, reducing vibration and enhancing control during operation.

Durability and Longevity

Festool’s proprietary diamond bonding technology creates a resilient matrix that withstands high temperatures and abrasive forces. This results in:

• Extended tool life compared to conventional abrasive discs.
• Consistent cutting performance throughout the disc’s usable life.
• Reduced maintenance costs due to fewer replacements.

User Experience and Handling

Operators report that the Festool 768018 Diamond Disc offers excellent balance, minimizing hand fatigue during prolonged use. The multi‑colour system simplifies workflow by allowing quick identification of the appropriate grit without needing additional tools or markings.
