BRSCHNITT Diamond Cutting Discs, 3-inch

The three-disc set combines a 3-inch (75 mm) size with an arbor listed as 3/8-inch (10 mm), giving you a compact format for cutting masonry and stone when your tool accepts those dimensions. The listing names brick, granite, marble, concrete, stone and terrazzo among its intended materials, and says the discs can be used for wet or dry cutting. It also describes a turbo-rim design intended to leave a smoother finish than a segmented blade, however, the product title calls the rim continuous, so the rim description is not entirely consistent.

Key specifications

The set contains three diamond cutting discs. Each is listed with an 8 mm diamond height, 2 mm segment thickness and a 3/8-inch (10 mm) arbor. The size is given as 3 inches (75 mm). These are the details to match against your tool before choosing: the arbor and disc dimensions matter more than a general claim that a blade is suitable for an angle grinder.

The description says the discs are suitable for wet or dry cutting, while recommending dry cutting for general building materials. It lists a range of masonry and stone applications, from brick to hard concrete. The listing also claims a longer life than conventional abrasives, but gives no testing conditions for that comparison, so treat it as a manufacturer claim rather than a predictable service-life estimate.

Who it’s for

This set is aimed at someone who needs small-format diamond discs for masonry or stone work and already has a compatible compact cutting tool. For example, a short cut through a brick or a stone piece can be easier to manage with a compact disc than with a larger blade, provided the tool accepts the stated arbor and disc size. It’s a good fit if your projects involve the listed materials and you want three discs on hand rather than a single replacement.

The description names the BOSCH GWS 10.8-76 VEC, Karl battery angle grinder and Milwaukee 2522-20 M12 FUEL 3-Inch Compact Cut Off Tool, as well as other battery angle grinders that match the specification. That is not a guarantee of fit for every version or setup. Check your tool’s requirements and the arbor size before buying. It may not suit you if you need a larger blade, a disc for a different mounting size, or a product with independently documented cutting-life comparisons.

Includes

The stated contents are three 3-inch diamond cutting discs. No extra arbor, adapter or other accessory is listed, so don’t assume one is included. The discs are described for granite, marble, stone, terrazzo, brick and concrete, the listing does not give a full cutting-depth figure or explain how performance varies between those materials. If your work is mainly on reinforced concrete, keep in mind that the product name mentions it, but the description does not provide separate guidance for that application.

Three specific questions

Can the discs be used wet or dry? The listing says both are possible and recommends dry cutting for general building materials. Follow the instructions for your tool and the material being cut.

What should I check for compatibility? Match the 3-inch (75 mm) disc size and 3/8-inch (10 mm) arbor against your tool’s requirements. The named tool models are examples, not a substitute for checking your exact setup.

Is the rim design clearly specified? Not quite. The product title says continuous rim, while the description refers to a turbo-rim design. Based on the listing, that wording is worth clarifying if rim style is central to your choice.

Final verdict

These BRSCHNITT discs make sense when you need a compact, three-piece diamond set for the listed masonry and stone materials, and your tool matches the stated dimensions. They are less compelling if you need precise performance evidence, a clearly documented rim design or guidance for a demanding reinforced-concrete job. The practical decision is straightforward: confirm the arbor and disc size first, then weigh the broad material list against the limited detail on cutting depth and real-world service life.
