the uses for diamond tipped blades do go beyond masonary- you can get diamond impregnated blades for cutting metal, also. Most diamond blades are used for cutting concrete, brick, stone, block, tile, asphalt, fibercement siding, and terrazzo. There are many different styles of blades, and each has a semi-specific material to cut. Some blades require that they have a constant stream of water sprayed on them to cool the blades. Some are only for green, uncured concrete and asphalt. Some are for tile or porcelean only. The difference isn’t the diamonds, but the material the blade is made out of. The medium that holds the diamonds in place in the blade is designed to wear at a different rate-depending on the material. Using a blade designed to cut block or cured concrete to cut asphalt will result in the blade galling up-basically you’ll wear the exposed diamonds off, but the asphalt isn’t abrasive enough to wear the medium down enough to get to the next layer of diamonds, and the blade will stop cutting until you run it in a block or cured concrete. Using a blade that’s designed to be used with water without water will result in the blade warping, and it will be impossible to cut a straight line. Also, different blades are designed for each specific tool they are used on. That means that they are designed to run at different RPM’s. Never use a blade in a tool(such as a gas powered cut off saw) that spins faster than the recommended safe rpm for the blade-it will basically fly apart.

The other answers gave you the difference between blades. I’ll go a step further. Different blades have specific intended purposes. You should use the type of blade to fit your purpose. I cut mainly wood and have about a dozen different blades, some fine cut, some rip, etc. I use a torch and abrasive disk blade for cutting metal. I have never cut tile so I don’t have any diamond blades. I discovered many years ago that a sharp tool works far better than dull ones.

Diamond blades are used to cut masonry. Period. Use a carbide tipped blade to cut through wood (diamond will just burn it), and use a metal cutting blade for metal. There are different types of metal blades for ferrous (steel) and non-ferrous metals. There is a correct tool for each job, and this is a perfect example. Good luck.
