The best way to stay efficient on the job site is by minimizing downtime. Choosing the wrong blade to put on your cut-off saw can waste an entire day if you aren’t careful. Knowing what equipment, you are cutting with, when you are cutting, and what material you are cutting can eliminate any confusion when selecting your diamond blades.
1. What Material Are You Cutting?
Diamond blades are made with different levels on bonded segments, hard and soft. To get the most out of your diamond blade, the segment and blade should be matched to the material it will cut. Being able to identify the type of material to be cut and the aggregate of the material can extend the life of your diamond blade drastically.
2. What Equipment Are You Using?
Understand that the horsepower you are cutting with impacts the productivity and longevity of your diamond blade. The size of the blade should match the saw’s maximum horsepower. Cutting with a saw that runs too fast can cause the diamond blade to glaze over and get too hot. Cutting with a saw that runs too slow greatly affects the productivity and effectiveness of your diamond blade.
3. What is Your Depth of Cut?
Know how deep you need to cut before selecting your diamond blade allows for a more precise and accurate cut. The maximum cutting depth of a blade depends on the saw type and the saw’s components. Blade guards and motor housings can decrease the maximum depth of cut you can make with a blade.
4. Are you Wet or Dry Cutting?
Knowing whether you need to use water with your diamond blade is important when selecting a blade. Any blades that are designed to cut wet MUST be used with water, while blades that are designed to cut dry can be used to cut both wet and dry.

5. Can I get more longevity from my Diamond Blade?
A diamond blade's life depends on many different variables. One key factor of a diamond blade's life is the quality of the diamond blade. Diamond blades have different concentrations and quality of diamonds within the segments. A blade with a higher concentration and quality of diamonds will perform better and last longer. Another factor is the material you are cutting. Make sure that your blade is the right spec for the aggregate you are cutting. Cutting a hard material like concrete will need a softer bonded segment in the blade than one used when cutting a more abrasive material like asphalt. A harder material requires more diamonds to be exposed in the segment. Soft bonded segments allow the diamonds to rise to the top to be exposed and grind away the material quickly. You could use a blade designed for hard material for asphalt, it will cut fast, but the diamond blade won't last long.
The saw that you're are using also makes a difference in the life of your blade. A saw with a higher RPM will wear a blade faster than a saw with low RPM. The saw operator plays a big role in the longevity of the blade. Applying too much pressure on the blade tends to wear the segments down faster than someone applying minimal pressure.
Final Tips for Longer Life
- Use a wet blade only when wet cutting
- Don't bury the blade, let the saw cut by itself.
- Make sure the blade is installed correctly
