Helping Pros Take on the Toughest Cuts with Confidence

How To Select Your Diamond Blade

Cut further, faster by selecting the right diamond blade for your cutting application! The best way to stay efficient on your job site is by minimizing downtime. If you have to stop and change your diamond blade every few cuts, you lose a lot of valuable time. Choosing the correct diamond blade to put on your cut-off saw makes you efficient by allowing you to cut longer and faster. Cut with confidence by asking yourself these 5 questions before selecting your diamond blade:

  1. What Material Are You Cutting?
  2. What Equipment You Are Using?
  3. What is Your Depth of Cut?
  4. Are you Wet or Dry Cutting?
  5. How Long Do I Need This Blade To Last?

 

1. What Material Are You Cutting?

Diamond blades are made with different styles of bonded segments. The segment bonds range from hard-bonded, which is used to cut soft aggregate materials like asphalt or sandstone, to soft-bonded segments, designed to cut hard aggregate materials like concrete or trap rock. To get the most out of your diamond blade, the segment bond hardness and blade should be matched to the material you are cutting. Identifying the type of material to be cut and the aggregate of the material extends the life and speed of your diamond blade drastically.

2. What Equipment Are You Using?

Your diamond blade's recommended operating speed should match the RPM of the saw you are using. The recommended RPM your diamond blade should be running at depends on the diameter of the blade. A blade that is being used at the recommended RPM will last longer and perform better than one used at the wrong RPM. The saw you select depends on the horsepower and on the size of the job you are on. Larger jobs require larger saws, which require larger diameter blades. Check out the Diamond Blade Operating Speeds chart below to see what your blade's recommended operating speed is.

3. What is Your Depth of Cut?

Knowing 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 diamond blade depends on the saw's specs and components. Blade guards and motor housings can decrease the maximum depth of cut you can make with a blade. Check out our Maximum Blade Cutting Depth Chart to see what diameter blade gets what cutting depth.

4. Are You Wet or Dry Cutting?

Knowing whether you need to use water when making your cut is important when selecting a blade. Diamond 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. The following quote is from Phil White, one of the many diamond blade experts at Esch Supply.

 

Wet Cutting Concrete
"Wet cutting is one of the most effective ways to cut concrete, masonry, stone, or even asphalt. Dust exposure is kept to a minimum and your diamond blade is less likely to overheat. The key is using the right amount of water. The slurry should almost have a chocolate milk consistency to it." 

-Phil White, Esch Construction Supply

 

 

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 better quality diamonds will perform better and last longer. Another factor is the material you are cutting.  Make sure your blade is the right spec for the aggregate you are cutting. Cutting a hard material like concrete will need a softer bonded segment 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 expose more diamonds at a time help to grind away the material quickly. For instance, using a diamond blade with a soft bond to cut asphalt will still cut very fast, but you will see a large decrease in the life of your blade.

The saw and the saw operator make a difference in the life of your blade. Applying too much pressure when cutting can affect the life of your blade. For optimal blade life don't push, let the saw blade do the work. Don't bury your blade! Burying the blade can cause excessive heat and wear from cutting material such as Class 5. Avoid buring the blade by Step Cutting.

 

Final Tips for Longer Life

    • When using a wet blade make sure to use water.
    • Let the saw do the work! Step cut instead of buring the blade.
    • Make sure the diamond blade is installed on the saw correctly.
