Overview
The Festool 768023 DIA THERMO-D130 PREMIUM Diamond Disc is a 130 mm diamond grinding disc built for material removal with Festool RG 130 series renovation grinders. This is a diamond disc designed for removing thermoelastic materials from concrete and screed. Model number 768023. If you are dealing with flooring adhesive, adhesive residue, bitumen, or coatings that tend to heat up, smear, and gum up a regular wheel, this accessory is aimed right at that problem.
What makes this disc different is the way it works the material. Festool states that the diamond layout scrapes rather than sands, which matters on jobs where heat buildup turns removal into a mess. Instead of loading up quickly and losing bite, the disc is designed to resist clogging and keep cutting. That means faster removal and less time stopping to deal with a packed wheel.
The 5-1/8 inch diameter gives you the correct size for the intended grinder platform, and the diamond construction is built for long service life in abrasive conditions. Festool also calls out temperature-resistant diamonds, which is a practical feature here because the whole point of this disc is handling materials that get messy when they get hot. If a spec matters, this one does. A disc that holds up to heat is exactly what you want when removing bitumen and stubborn adhesive layers.
On the job, this is less about finish quality and more about controlled, efficient surface prep. It is made for renovation and flooring removal work where you need to strip bonded material off a mineral base without constantly fighting buildup. Used on concrete and screed, it is suited for removing thermoelastic coatings and residues that can slow down general-purpose grinder wheels.
Compatibility is straightforward. This Festool diamond disc is listed for the RG 130 ECI and RG 130. That makes it a system accessory rather than a universal wheel you buy and hope fits. If you already run one of those Festool renovation grinders, this disc gives you a specialized option for coating and adhesive removal. Festool also lists easy disc replacement, which helps when you are swapping setups between different removal tasks.
Who should buy it? Flooring contractors, remodelers, concrete surface prep crews, and serious users doing adhesive and coating removal with an RG 130 platform. If your work regularly involves parquet adhesive, adhesive residue, bitumen, or similar thermoelastic material, this is the right type of diamond cup disc to keep on hand. If you do not own an RG 130 ECI or RG 130, this is the wrong accessory. It is purpose-built, and that is exactly why it makes sense for the right user.
Cut Through Heat-Sensitive Removal Work
This is the kind of accessory you buy to solve a specific removal problem. On thermoelastic coatings and adhesive residue, the goal is steady removal without the wheel loading up every few minutes.
- Designed for thermoelastic materials that smear when heat builds up
- Recommended for concrete and screed surface preparation
Purpose-Built for the RG 130 Platform
Fit matters with grinder accessories. This disc is listed specifically for Festool RG 130 ECI and RG 130 machines, so it is meant to work as part of that surface-prep system rather than as a generic substitute.

Tool Nut’s Take
The Right Wheel for the Ugly Removal Jobs
The Festool 768023 DIA THERMO-D130 PREMIUM Diamond Disc is a niche accessory, but for the right user it is exactly the kind of niche that saves real time.
- Who it’s for: Pros using an RG 130 ECI or RG 130 for coating, adhesive, and bitumen removal on concrete or screed.
- Why it stands out: It is designed to scrape heat-sensitive material instead of just grinding at it, which helps reduce clogging and keeps removal moving.
- Worth knowing: This is not a universal buy. It makes the most sense if you already own the matching Festool renovation grinder and regularly tackle thermoelastic material removal.
