A close-up of a diamond blade, showing worn metal behind the diamonds on the blade. Precise sectioning is typically done on smaller precision cutters, but can also be done on larger saws.

The steel blade cores for these aggressive uses are thicker, heat-treated, precision-ground and tensioned. The extra thickness and heat treatment allows the core to withstand the flexing stress from the heavier equipment and higher horsepower. The precision grind on the surface minimizes the drag while the establishing the tension of the flatness of the blade at a specific rpm range. Such laser welded diamond saw blades are used for cutting concrete, asphalt or some dry cutting. The wear rate and cutting speed for the diamond segment and diamond saw blade can be classified to the ability of a metal to resist wear from abrasion. Metal bonded with low abrasion resistance like bronze are considered as soft bond.
They are made by notching the rim of the blade blank and embedding the diamonds into the notches. The code, which is in a three-letter format separated by dashes, will be permanently imprinted on the blade. And it will tell you at a glance whether the blade is for wet or dry use, what type of material it can cut, and the saw type it’s designed to work with. Expect to pay several hundred dollars or more, depending on the blade diameter.

To locate a contractor in your area, visit the member directory of the Concrete Sawing & Drilling Association . The metal core, a precision-engineered steel disk with a segmented rim that holds the diamonds.
The soft bonds are mostly made up of soft metals for example Bronze and are common when cutting very hard less abrasive material like marble. The hard bonds are mostly made up of hard metals for example Tungsten Carbide and are common when used for cutting very soft abrasive materials like asphalt or freshly poured concrete. One additional consideration is when using diamond blades on concrete with steel in it. Rebar is the backbone of concrete construction and the bane of bits and blades alike. If cutting rebar when exposed, a diamond blade will make quick work of the cut, but it greatly reduces the life of the blade. This is because diamond blades “cut” by grinding the material as opposed to other blades that rip and tear. When cutting concrete where rebar is sure to be found, it is often best to use a continuous rim blade with a supply of water. An actual gem among saw blades, the diamond’s famous hardness provides cutting on some of the hardest materials on earth.

Use the correct wrench to remove the arbor nut while holding the blade lock button. Push the blade lock and slowly rotate the blade with your other hand until the blade lock mechanism engages. However, using a circular saw blade on a bench saw has its pros and cons.
Dry blades usually have a slightly softer bond to allow easier cutting without water to cool and lubricate the cut. That is why most diamond blades utilize water to dissipate heat and increase the longevity of the blade. Additionally, the water helps keeps the dangerous dust that, when cutting concrete, contains silica. OSHA has numerous regulations restricting the amount of dust created when cutting. Unlike most other blades, diamond blades don’t cut the material. Instead, they use friction created between the diamond-bonding matrix and the material being cut to work like a grinding wheel. Metal Bond – The diamond crystals are held in place by a formulated mixture of various metals which determine the rate at which the diamond crystals are exposed. A harder bond reduces diamond erosion, which is designed for softer applications like green concrete or asphalt. A softer bond increases diamond erosion and is better suited for harder material such as granite or cured concrete. U.S.SAWS Blades are made with the highest diamond content available to cut faster and last longer.

However, water isn’t a good coolant, because the flashpoint is quite low compared to the oils, which are commonly in use. Frequently, on some social media sites as well as some forums, questions arise about the type of saw blades to buy for trimming or slabbing rock, and how to sharpen the blades.

For something as simple as cutting wood, there is no reason to go for a more expensive saw blade. Depending on the kind of woodworking, you will want to be careful about how many teeth the blade has. If you are just cutting through large amounts of lumber, then I recommend going for a blade with a lower number of teeth, it will save you time. If you need precision, make sure you get a blade with a high number of teeth, the more teeth, the more precise your cuts will be. Very often you will see these kinds of blades having teeth numbering in the 60 to 80 range.
