Festool 768017 Diamond Disc – Multi‑Colour

The Festool 768017 Diamond Disc, also known as the DIA HARD-D130 PREMIUM, is a high‑performance abrasive tool designed for precision grinding, sanding and polishing of hard materials such as concrete, stone, tile, and epoxy. Its multi‑colour construction indicates the type of diamond grit used, allowing users to select the appropriate disc for their specific application.

Key Specifications

• Diameter: 130 mm (Ø 130 mm)
• Inner Diameter: 25 mm / 22.2 mm (Ø 25/22,2 mm) – compatible with a wide range of spindle sizes
• Manufacturer Number: 768017
• Grit Colour Coding: Multi‑Colour – each colour corresponds to a specific grit size and hardness level
• Material: Premium diamond abrasive bonded in a durable matrix for extended life and consistent performance

Design & Construction

The disc features a robust, multi‑layered design that balances strength with flexibility. The outer layer contains high‑density diamond particles that provide aggressive cutting action, while the inner core offers structural support to maintain shape during heavy use. This construction ensures minimal vibration and maximum stability when mounted on Festool or compatible rotary tools.

Performance Characteristics

• High Cutting Efficiency: The diamond particles are engineered for rapid material removal, reducing the time required for grinding tasks.
• Consistent Edge Retention: The premium bonding matrix keeps diamonds firmly in place, preventing premature wear and maintaining a sharp cutting edge throughout the disc’s life.
• Versatility Across Materials: Suitable for hard concrete, stone slabs, ceramic tiles, epoxy surfaces, and other dense substrates.
• Reduced Heat Generation: The multi‑colour grit system is designed to dissipate heat effectively, preserving the integrity of both the disc and the workpiece.

Applications

The Festool 768017 Diamond Disc excels in a variety of professional settings:

• Concrete Finishing: Smooths and polishes poured concrete floors, walls, and countertops.
• Tile & Stone Work: Grinds and refines ceramic, porcelain, and natural stone tiles for installation or repair.
• Epoxy Surface Preparation: Removes excess epoxy and creates a uniform surface for subsequent coatings.
• Surface Profiling: Creates textured patterns or prepares surfaces for adhesive bonding.

Installation & Compatibility

The disc’s inner diameter of 25 mm / 22.2 mm allows it to fit securely on most Festool rotary tools and other compatible power equipment. When mounting, ensure the spindle is clean and free from debris to achieve optimal contact and prevent wobble.

Maintenance & Longevity

To maximize lifespan:

• Use at Recommended Speeds: Operating within the manufacturer’s speed range prevents overheating and premature wear.
• Regular Cleaning: Remove dust and debris after each use to avoid clogging of diamond particles.
• Inspect for Damage: Check for cracks or chips before re‑use; replace if any structural integrity is compromised.

Why Choose Festool?

Festool’s reputation for precision engineering and quality materials makes the 768017 Diamond Disc a reliable choice for demanding projects. The multi‑colour system provides clear visual cues, enabling professionals to select the exact grit needed without guesswork.

Conclusion

The Festool 768017 Diamond Disc – Multi‑Colour is an essential tool for anyone working with hard surfaces. Its superior construction, versatile applications, and consistent performance make it a standout choice in the realm of diamond abrasives.
