Info on the different bonds used to make diamond tools

[Diemaker]

I was responding to a post and while doing so ran across this list of articles on the four different bonds used for diamond tools from a Canadian manufacturer of said tools that I figured some here would find interesting. I think it would be better posted as its own so here it is. Most of the info is geared for cutting "stone" but the fundamentals apply to cutting anything that diamond is used for, and if you replaced the diamond with CBN the info would still be the same. The page on sintered tools talks about bond hardness, which is important when working with "stones" of different hardness and its importance is widely recognized. I think it is just as important to stones used for sharpening knives but its importance is less recognized in our circles. The bond is just as important as the abrasive size in how a stone works, if not more so. Everyone talks about abrasive size when comparing stones, but little is said about the bond.

Just starting to look at that now. Looks like a good reference. Thanks for linking that.

I'm not sure if this is relevant to the discussion, but...
I fell into a diamond blade ( concrete cutting) rabbit hole years ago, it was kinda shocking to learn that the harder the material being cut, the softer the bonding matrix, so me w diamonds are available for cutting
The softer material being cut has a stronger matrix to hold the diamond better to allow it to cut longer. I've seen this at work using the wrong blade and either extreme premature wear, or the blade not cutting at all.
