How to Cut Concrete Using Your Diamond Blade
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.
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
Make sure that if you are using a diamond blade that has been used before, that you check that it is in good condition and that the arbor hole hasn’t been damaged.
Also, check that the blade hasn’t been warped out of place. Check the key components of your masonry saw before you go to work, such as belts, bolts and oil levels.
Note the condition of the power cord if you are using an electric motor. Make sure that the water is free flowing to both sides of the blade.
Never force the blade when cutting, as this can damage the material. Let the blade do the cutting itself. Also, if you apply excessive pressure from the side to attempt to steer the blade, it can be dangerous and reduce the blade life.
Replacing a Diamond Blade
Diamond blades take on more damage than a standard saw due to the type of materials being cut. You can naturally look at the diamond blade to know when it may need replacing as the segments will be smooth and worn down. More tell-tale signs that show your diamond blade needs replacing include:
- 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.
