I recently bought a Pro-Slicer Gorilla blade (6") for my trim saw and was surprised by how little diamond is on it. It's a plated blade, but the diamonds are plated in clusters about 1/4" wide around the circumference. The Gorilla as sold as having "coarse diamonds for fast cutting". I cut about 20 preforms from agate and jasper and I would estimate that the blade is about 1/2 gone.
It might be good for opal or other softer stones, but it's not a good match for agate. I was looking for a blade that could be used with water soluble coolant without draining every time and that could be run at 3450 rpms.
Every other rust-free blade that I've looked at looks similar to the Pro-Slicer. I ordered a new coarse blade from Lopacki and will just have to drain the saw, I guess.

I use the Pro-slicer blades on my 8" saw with oil and they last me for many months of hard use. Maybe the water doesn't work well with these types of blades? Bob

That could be it, Bob, although it is clearly advertised as being appropriate for water soluble coolants. Maybe I'm wrong about the amount of life left. That would be a nice surprise! I'm glad you're getting more life out of them.

Any plated blade will have less life than a sintered blade. Generally the advantage of a plated blade will be thinner kerf. Of course, usually cheaper, sometimes much cheaper. Anybody seen the Indian Jeweler Supply new blades? Exact copy of the Proslicer. Proslicer manufacturer is crying the blues because they were formerly his biggest customer.
