Diamond Blade Duration – Get the Most From Your Diamond Blades

Important things to know about buying diamond saw blades.

When dealing with diamond blades it can be a tough decision choosing the right saw blade and knowing the difference between value and appearance. There are many different types of saw blades along with different designs as well. The real deciding factor should be how much the blade will cost you and how much it will cut. By just looking at a diamond saw blade in a catalog or picture, you can not tell much about its quality or worth. You might be able to notice a high diamond concentration in the segments but you will not know how fast or how long it will cut.

The best way to value a diamond saw blade is by choosing the bond specifically made for the material you need to cut and applying good cutting techniques to prolong the saw blade's cutting duration. If you would like to compare two different saw blades then try to repeat the process under the same conditions and note cutting speed vs. cutting duration of the blade.

From this we can determine our cost per foot by dividing the cost of the diamond blade by the amount the saw blade cut. This is a good way to calculate what your cutting costs will be and know how much you can cut so you do not fall short or buy too many.


14 "Asphalt Saw Blade Cost = $ 180 Feet cut at 1" deep = 12,000 ft Formula: 180 / 12,000 = 0.015

Cost per foot at 1 "deep is 1.5 cents and cuts 12,000 ft.

Cost per foot at 2 "deep is 3.0 cents and cuts 6,000 ft.

Cost per foot at 4 "deep is 6.0 cents and cuts 3,000 ft.

Now we know if we have to cut 9,000 feet at 4 "deep we will need 3 diamond blades. If you're satisfied with the cutting duration of your diamond saw blade but not so happy with the cutting speed, maybe you could try a thinner kerf saw blade, turbo saw blade, turbo segmented blade or a similar saw blade with a softer bond.

If you decide you need faster cutting and want to try with a softer bond, also remember to keep in mind that a softer bond will wear down faster so the cost per foot will go up. Faster cutting is important when deadlines must be met and time is limited. Another important factor is to make sure you do not cut abrasive materials with a soft bond diamond blade. Doing so will wear down the metal segments before the diamonds are fully used. For example you should not cut asphalt with a saw blade designed for cutting reinforced concrete.

Sometimes you will need to cut several materials and you end up deciding whether you would rather use a general purpose or specific blades for each application. This really depends on how much material needs to be cut. If it's a large job where some diamond blades will be used, it would probably be a good idea to buy separate diamond blades for each material.

If the cutting jobs are small it may be more convenient to use a general purpose or multi-purpose diamond blade to save time by not having to switch diamond blades so often. However general purpose diamond diamonds will usually have a fairly soft bond so they will wear down very fast in highly abrasive materials such as asphalt or green concrete.

Use water whenever possible to act as a coolant and reduce the amount of dust from the cutting. Water will help prolong blade life by removing some of the excess slurry and keeping the blade from overheating. Apply these cutting tips and you'll notice extended blade life and savings.
