PRODIAMANT is a German tool brand — founded in 2012, owner-led to this day.

We are specialists in professional diamond tools: cutting blades, grinding wheels and joint-cleaning tools for concrete, stone, masonry and tile. Every tool we sell is specified, tested and refined by our own team in Germany — and now stocked in U.S. fulfillment centers so it reaches your jobsite in days, not weeks.

What defines us

  • Developed in Germany — specification, testing and continuous improvement of our tools happen in-house at our facility in Neckarwestheim, Germany.
  • Owner-led since 2012 — founders Benjamin and Rainer still run the company day to day. Short paths, personal standards, no anonymous corporation.
  • Specialists, not generalists — we make diamond tools. Nothing else. That focus shows in every cut.
  • Honest advice — we tell you which tool fits your job, and just as clearly which one doesn't. A mortar rake built for lime mortar is sold as exactly that.

In-house product development: every blade is specified and tested

Trusted by professionals

Tens of thousands of customers across Europe work with PRODIAMANT tools, and thousands of verified Amazon reviews back them up.
