There are a few rules that should be in place when cutting with a diamond blade. They go as follows:

1. Have a Plan

Measure at least three times when marking your cutting line. Also, consider if there will be rebar (steel re-enforcement) embedded within the material you are cutting, as well as any gas lines or electric lines. You want to know this before you start to cut.  

2. Use the Right Diamond Blade for Your Masonry Saw and Material

You should only use a blade that meets the specifications of your machinery. If the blade doesn’t fit the machinery properly, or has the wrong RPM, you risk damaging the blade, the material, as well as creating a safety risk.

Also, wet cutting diamond blades should be only used for cutting wet concrete, and vice versa for dry cutting. Dry cutting blades are most suitable on low horsepower masonry saws.

HOT TIP!

If you have to pick between a bond that is too soft or too hard for your material, lean toward the side of too soft. A bond that is too hard can cause the blade to overheat at a faster rate and can cause the blade to crack. A blade that is too soft will still cut – you just won’t get a long life from your diamond blade.

3. Check the Blade and Masonry Saw Before You Use It

If you’re reusing a diamond blade, inspect it for damage—especially around the arbor hole. Ensure the blade isn’t warped and check your masonry saw’s key components like belts, bolts, and oil levels.

If you’re using an electric motor, examine the power cord for wear. Confirm water flows freely to both sides of the blade to keep it cool during cutting.

Avoid forcing the blade or applying side pressure to steer it. Let the blade cut naturally to prevent damage and extend its life.

Replacing a Diamond Blade

Diamond blades endure more wear than standard saw blades due to the tough materials they cut. You’ll know it’s time to replace one when the segments appear smooth or worn down.

• Less-efficient: A worn out, smooth diamond blade will cut at a far slower rate than it did when you first bought it.
• Glazed blade: This shows that blade has been to cut a softer, less abrasive material than what should have been cut through. You may be able to bring the diamond particles back to their original form by cutting through a harder, more abrasive material, but this doesn’t always work.
