How to Use a Concrete Saw

The combination of what to do, what not to do and what to focus on will help you get the proper use of a concrete saw.

Choosing the right tool for the job

This could be the most important choice you have to make when it comes to concrete cutting. It is this point that many DIY users go wrong; they try to make use of tools such as chisel and sledgehammer to get the job done. While these tools are not exactly ineffective, they are not the best choice for a job that requires precision and accuracy.

Our recommendation is to go for a concrete saw, particularly a specialized circular saw with a high current power range. This is ideal for a heavy-duty job. Even professionals whose job involves specialized and more heavy-duty concrete cutting will benefit from this.

Choosing the right diamond blade

You cannot cut through concrete with a concrete saw without having an accompanying diamond blade. Now that you have known this; you have to decide which diamond blade is more adept to the work at hand.

There are three types of diamond blades used for concrete cutting; this makes for the choice available to you.

  • Abrasive Corundum Masonry Blades: cheap, readily available on the market and possess the ability to cut through concrete as well as asphalt (proving their potential for commercial use). Nevertheless, this is an economical choice.
  •  Dry-Cutting Diamond Blade: comes with a serrated or toothed rim (in most cases) that helps to cool the blade; also to eject waste while the tool is in use. The best choice for concrete cutting that involves making a series of gradually deeper cuts. The downside to using dry-cutting is the amount of dust that accompanies it while the tool is in use.
  • Wet-Cutting Diamond Blade: can come with teeth or smooth; the water helps to cool and lubricate the blade while it is in use. It also helps to reduce the amount of dust that is a by-product of using a concrete saw. Gives the fastest and cleanest cut, making it the best choice for jobs that prioritize precision and accuracy.

Make sure that the material is hard enough for the concrete saw. Yes, when the material is too soft for the diamond blade, it stops working. This is something you need to ensure before you start working. Also, the harder the material, the sharper the diamond blade gets.

Things to Do While Using the Saw

  • Start with a single surface cut. This is the best way to begin your concrete cutting because doing this will let you mark an exact area in which to make your cuts along.

  • Wear protective gear when using the saw. This is to prevent your body from harmful materials such as debris that can lead to minor and serious injuries.

Things Not To Do

  • Don’t force the blade into the concrete surface or structure; exerting too much pressure on the saw negates the recommended way of handling the saw, which is to let the saw’s weight do the cutting.
  • Don’t forget to map out the area that you intend to cut
