This is a \u003cstrong\u003ediamond disc designed for grinding very hard concrete and masonry substrates\u003c\/strong\u003e. Model Number: \u003cstrong\u003e769166\u003c\/strong\u003e. If you are running a Festool RG 130 ECI or RG 130 and need an accessory that holds up on demanding concrete work, this is the disc built for that job.\u003c\/p\u003e \u003cp\u003eWhat matters here is not just the diameter, but how this wheel is set up for hard material removal. Festool rates it for very hard materials and hard concrete harder than B35, which makes it a focused accessory rather than a general-purpose wheel. That matters on the job because hard concrete can burn through lighter accessories fast. A disc built specifically for that material keeps cutting and grinding more consistently instead of glazing over early.\u003c\/p\u003e \u003cp\u003eThe 7 mm segment height is one of the key details. In plain terms, that gives you more usable diamond segment to work with over the life of the disc. Combined with Festool's premium construction, the result is longer service life when you are grinding on hard, abrasive surfaces. If you do repeated concrete surface prep, coating removal on hard substrates, or correction work where the base material is tough, that durability pays off.\u003c\/p\u003e \u003cp\u003eThis disc is sized at 130 mm with a minimum arbor diameter of 25 mm and a maximum inner diameter listed at 22.2 mm. It is designed to match the Festool RG 130 platform, so fitment is not a guessing game when you are already running that machine. Festool also calls out easy disc changes in just a few steps, which is a practical benefit when you need to switch accessories between passes or move from one stage of grinding to the next.\u003c\/p\u003e \u003cp\u003eJobsite practicality is a big part of why someone buys a disc like this. Surface prep work is rough on accessories, and hard concrete is one of the fastest ways to expose weak grinding wheels. This Festool diamond cup disc is built for wet or dry use, and it is rated for up to 11,750 RPM, so it is meant to work at the speeds these concrete grinders run. That gives pros a disc that matches the machine and the material instead of forcing a compromise.\u003c\/p\u003e \u003cp\u003eCompatibility is straightforward. The DIA STONE-D130 is suitable for the Festool RG 130 ECI and RG 130 grinders. If that is your platform and your work leans toward hard concrete or very hard mineral-based substrates, this is the right style of accessory to keep on hand. It is especially relevant for concrete contractors, remodeling crews doing slab or substrate correction, and anyone handling masonry surface prep with the RG 130 system.\u003c\/p\u003e \u003cp\u003eWho should buy it? Buy this if you already own a Festool RG 130 series grinder and regularly deal with very hard concrete where accessory life and consistent grinding matter. If you only occasionally touch softer material, this may be more specialized than you need. But for hard-substrate grinding, that specialization is exactly the point.\u003c\/p\u003e \u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e \u003csummary\u003e\u003ch2\u003eMade for Very Hard Substrates\u003c\/h2\u003e\u003c\/summary\u003e \u003cdiv class=\"acc-body\"\u003e \u003cdiv class=\"row\"\u003e\n\u003cdiv class=\"img\"\u003e\u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/50183916585254_d860a599b453.jpg\" alt=\"Festool 769166 DIA STONE-D130 PREMIUM Diamond Disc product close-up showing the segmented diamond cup wheel for hard concrete and masonry grinding\" class=\"tnblock-img\"\u003e\u003c\/div\u003e\n\u003cdiv class=\"copy\"\u003e\n\u003cp\u003eThis is not a catch-all grinder wheel.
