Absolutely brilliant! I have decades of experience with diamond blades, this is a really good one. We're cutting thousands of granite setts at the moment and other blades we've had have really struggled where as this just ploughs straight through.
A good tip for all diamond blades when they stop working so well is to cut through any softer material for a bit to clean the blade off again and gone off sharp sand and cement screed is the best thing I've found for this
Usually use very cheap blades but this is far better and lasts longer
I needed a blade that I could just leave on my disc cutter for all applications. It seemed that this Mexco blade could do it. So far so good, we have used it to cut some old concrete and some block paving/slabs.
