Key Features
Built for Abrasive MaterialThis diamond disc is made for sand-heavy substrates that eat up standard wheels. It removes material quickly on screed, fresh concrete, adhesive residue, sand-lime brick, tiling adhesive, and cellular concrete. Long-Wearing Segment DesignThe 9/32 in. (7 mm) diamond segment height gives the Festool 768018 DIA ABRASIVE-D130 PREMIUM Diamond Disc a long working life. That means fewer disc changes and more grinding done before you need a replacement. Fast Swap, Less DowntimeFestool designed this grinder wheel for quick disc changes on the RG 130 platform. If you switch between surface prep tasks during the day, that saves real time.
Overview
The Festool 768018 DIA ABRASIVE-D130 PREMIUM Diamond Disc is a 130 mm diamond grinding disc built for surface preparation with Festool RG 130 grinders. This is a diamond disc designed for grinding abrasive mineral-based materials on smaller surfaces. Model number 768018. If you spend your time removing stubborn material from sand-rich substrates, this is the wheel meant for that job.
Where this disc matters is material choice. Sand-based materials, screed, fresh concrete, adhesive on screed, sand-lime brick, tiling adhesive, and cellular concrete are all hard on accessories. The DIA ABRASIVE-D130 PREMIUM is built specifically for those abrasive substrates, so it keeps cutting where a lesser wheel would wear down too fast. That makes it a practical choice for renovation, masonry prep, and concrete surface cleanup.
The big number here is the 9/32 in. (7 mm) segment height. That extra usable diamond segment gives the disc a longer service life, which matters when you are grinding surfaces that chew through consumables. Festool also lists an active surface of 5.36 in² (3,460 mm²), giving you solid contact for controlled stock removal without stepping up to a larger, harder-to-manage cup wheel.
Fitment is straightforward. This disc is suitable for the Festool RG 130 ECI and RG 130. Diameter is 5-1/8 in. (130 mm), with a 1 in. (25 mm) arbor hole size listed in the source data, making it a dedicated accessory for that grinder platform rather than a general catch-all wheel. If you already run an RG 130 for renovation grinding, this is the right kind of accessory to keep in rotation for rough, sandy material.
On the job, the benefit is simple: faster grinding with fewer interruptions. Festool calls out easy disc changes in just a few steps, and that matters when you are switching from one substrate to another or replacing a worn wheel mid-project. The disc is also rated for a maximum speed of 11,750 RPM in supplementary data, which lines up with grinder use where stable, predictable accessory performance matters.
This is not a general-purpose cutting blade and it is not the accessory you buy for finish work. It is for contractors, remodelers, concrete prep crews, and serious users who need to remove material from abrasive surfaces efficiently. If your work involves renovation grinding, adhesive removal from mineral substrates, or prepping smaller concrete and masonry areas, this disc makes sense. If you do not own an RG 130 ECI or RG 130, it does not.
Made for Sand-Heavy Surface Prep
This disc is tuned for the kind of gritty material that wears out standard grinding accessories fast. If you are working on renovation prep or masonry cleanup, it is built to stay productive on abrasive substrates.
- Designed for sand-based materials, screed, fresh concrete, adhesive on screed, sand-lime brick, tiling adhesive, and cellular concrete
- Best suited to smaller surface areas where controlled grinding matters more than covering a huge floor fast
Long Life Where Cheap Wheels Burn Out
The segment design is the reason to buy this disc. The 7 mm segment height gives you more usable material, which translates into longer service life when you are grinding aggressive mineral surfaces.
- Segment height: 9/32 in. (7 mm)
- Active surface: 5.36 in² (3,460 mm²)
Purpose-Built Fit for the RG 130 Platform
This is a matched accessory, not a maybe-fit option. When you use the right disc on the right grinder, you get better balance, cleaner operation, and less time wasted fighting the setup.
- Suitable for Festool RG 130 ECI and RG 130 grinders
- Easy disc change in just a few steps helps keep surface prep moving
