Key Features
Built for Hard ConcreteThe Festool 768017 DIA HARD-D130 PREMIUM Diamond Disc is made for very hard substrates where a standard cup wheel slows down. It grinds old solid concrete fast and helps remove epoxy resin, coatings, and paint from concrete surfaces. Long-Wear 7 mm SegmentsThe 7 mm segment height gives this diamond grinding disc real service life on large surface areas. If you are doing concrete prep instead of a quick touch-up, that matters. Quick Disc ChangesFestool designed this disc for fast swaps on the RG 130 platform. Less time changing accessories means more time actually grinding.
Overview
Festool 768017 DIA HARD-D130 PREMIUM Diamond Disc is a 130 mm diamond grinding disc built for the Festool RG 130 ECI and RG 130 renovation grinders. This is a diamond grinding disc designed for concrete surface preparation and coating removal on very hard substrates. Model Number: 768017. If your job is old solid concrete, epoxy removal, or taking paint and coatings off concrete, this is the accessory aimed at that work.
What makes this disc matter is not just the fact that it is diamond, but how it is set up for hard-use surface prep. Festool rates it for fast grinding on very hard substrates, and the 7 mm segment height is a big part of that. On larger concrete areas, more usable segment height means the disc keeps working longer before it needs replacement, which is exactly what you want when you are trying to keep a prep job moving.
The 130 mm diameter gives you a good balance between coverage and control. It is large enough to handle broader concrete sections efficiently, but still sized for the RG 130 platform rather than a bulkier floor grinder setup. Festool also lists an active surface of 3,000 mm², which helps explain why this disc is better suited to larger surface grinding than a smaller, more aggressive point-contact accessory.
On the job, this disc is aimed at a specific kind of work: old, hard concrete that chews up lesser accessories. It is also meant for removal work, including epoxy resin from solid surfaces and coatings or paints from concrete. That makes it a practical choice for renovation, remediation, and surface prep before recoating or refinishing.
Festool calls out easy disc changes in just a few steps, which matters more than it sounds. Surface prep work often involves switching accessories as you move between conditions, and a disc that is fast to swap helps reduce downtime. This is especially useful for contractors using the RG 130 system as a dedicated renovation grinder rather than as an occasional specialty tool.
If you already run an RG 130 ECI or RG 130 and regularly work on hard concrete, this is the right kind of accessory to keep on hand. It is best for remodeling crews, masonry and concrete trades, and anyone doing serious coating removal from concrete. If your material is softer or your work is lighter-duty, this may be more disc than you need. But for hard substrate grinding, this is the one built for the job.

Pro Tip
On hard concrete, let the segment height do the work instead of leaning on the grinder. Heavy pressure usually just builds heat and wears the diamond faster, especially when you are stripping epoxy or old coatings across a big surface.

The right disc when concrete fights back
The Festool 768017 DIA HARD-D130 PREMIUM Diamond Disc is the one you buy when standard grinding accessories are not lasting and the substrate is flat-out hard.
- Who it’s for: Contractors, remodelers, and concrete prep crews already running an RG 130 ECI or RG 130 for real surface removal work.
- Why it stands out: The 7 mm segment height, 130 mm size, and hard-substrate focus make it a purpose-built concrete grinding disc instead of a general-use compromise.
- Worth knowing: This is a specialized accessory for hard concrete and coating removal. If that is not your material, you may be better off with a less aggressive disc matched to the job.
