Product description
Quick overview
This Bosch PRO multi-material diamond cutting disc is built for angle grinders and aimed at people who cut real construction materials all day. The headline here is “Long Life” – it’s claimed to last up to 1.5x longer than a Bosch Eco for universal cutting discs, which is the sort of difference that matters when you’re weighing cost-per-cut rather than cost-per-disc.
On paper, it’s designed for cutting across common building substrates like stone, brick and reinforced concrete, plus other everyday construction materials and composites. That multi-material angle can be handy if you don’t want a separate disc for every job.
Key takeaways
The practical appeal is straightforward: a 125 mm diamond disc with a standard 22.23 mm bore for locking-nut angle grinders, paired with an expected durability advantage.
It’s not the kind of item you buy for occasional DIY only, it makes more sense if you’re regularly cutting masonry-type materials and you want something that keeps working between swaps. That “Long Life” claim is useful, but do keep your own use conditions in mind—cutting speed, pressure and material hardness can change how long any disc really lasts.
Where it shines
If you spend time on site, the “professional accessory” approach shows in the spec choices. A 125 mm diameter with a 22.23 mm bore is a common setup for many standard angle grinders using a locking nut, so it should feel familiar.
In real-world use, imagine prepping a section of reinforced concrete for a run of services: you set up the grinder, clamp the disc using your usual locking nut method, and make controlled cuts through the masonry. For this kind of task—where blades can otherwise wear quickly—having a disc positioned around longer life is genuinely relevant.
Also, because the disc is described as multi-material, it can suit mixed jobs where you might move between stone/brick work and concrete elements without constantly changing consumables.
What to know before buying
A couple of points are worth checking so you don’t get stuck:
- Bore size matters: this disc is for a 22.23 mm bore, intended for standard locking-nut angle grinders.
- Confirm your grinder setup: the information provided focuses on locking nut compatibility, so if your grinder uses a different mounting system, you may need to look elsewhere.
- “For concrete and reinforced concrete” is the clear use case, but it’s still a cutting disc—accuracy and finish depend heavily on how you handle the cut (technique and control).
It’s also described as cutting various construction materials and composites. That’s helpful, but if you only ever cut one very specific material, a specialist approach can sometimes be more predictable than a broad “multi-material” stance.

Should you buy it?
It’s worth considering if you:
- regularly cut stone, brick, and especially concrete/reinforced concrete as part of construction work
- want a 125 mm diamond disc with a standard 22.23 mm bore for locking-nut angle grinders
- care about longer service life (and the idea of value-per-job rather than value-per-disc)
You may want to skip it if you:
- only do occasional DIY masonry cutting and would rather use a cheaper, simpler consumable for low frequency work
- can’t confirm your angle grinder uses a standard 22.23 mm locking-nut style fit
- need absolute certainty for one single material type where a specialist disc may give more consistent outcomes
