Cutting Concrete with an Angle Grinder: How To, Tips & Tricks

  Concrete is one of the most widely used construction materials in the world. Its strength, durability, and versatility make it ideal for a wide range of building and renovation projects. However, cutting concrete can be a challenging task, especially for inexperienced DIYers. The process requires specialized tools, techniques, and know-how to ensure the concrete is cut cleanly, safely, and effectively.

Today, we will explore how to cut concrete with an angle grinder, including tips and tricks that can make the process easier and more efficient. We will also introduce you to the different diamond saw blades from BSP, one of the leading manufacturers of cutting and grinding accessories for power tools.


What is an Angle Grinder?

An angle grinder is a handheld power tool that is commonly used for cutting, grinding, and sanding various materials, including concrete. It features a motor that drives a spinning abrasive disc or blade. Angle grinders are available in different sizes and power levels, depending on the intended use and the size of the material being cut.

How to Cut Concrete with an Angle Grinder

Before starting the cutting process, it is essential to take a few safety precautions. Here are the steps to follow:

1. Wear the right protective gear: Wear safety glasses, heavy-duty gloves, and a dust mask to protect your eyes, hands, and lungs from flying debris and dust.

2. Secure the concrete: Make sure the concrete is securely clamped or braced to prevent it from moving while you are cutting.

3. Choose the right blade: Select the appropriate blade for the type and thickness of the concrete. Diamond blades are typically used for cutting concrete because they are designed to withstand the high heat generated during the cutting process. But if choosing the wrong saw blade can result in poor cuts, damage to the concrete, and even harm to the operator.

BSP is one of the leading diamond blade manufacturers of cutting and grinding accessories for power tools. Their saw blades are designed for maximum performance and durability, making them ideal for cutting concrete and other tough materials. Here are a few of the different saw blades that BSP offers for cutting concrete:




 

l BSP Turbo Diamond Blade: This saw blade is designed to cut through concrete, asphalt, and other tough materials quickly and efficiently. The turbo rim design ensures fast cuts and extended blade life.

l BSP Continuous Rim Blade: The continuous rim design of this saw blade provides clean cuts and minimal chipping in delicate and precise cutting applications.

l BSP Segmented Rim Blade: The segmented rim design of this saw blade provides a faster cutting speed, making it ideal for heavy-duty cutting applications. The segments allow for a cooler blade, reducing the risk of blade damage.

4. Mark the cut line: Use a pencil or chalk to mark the cut line on the concrete. Make sure it is straight and accurate.

5. Adjust the blade guard: Before turning on the angle grinder, adjust the blade guard to the correct position. This will help protect you from flying debris and dust.

6. Start the grinder: Turn on the angle grinder and slowly lower the blade into the concrete along the marked cut line. Apply gentle pressure and allow the blade to do the work.

7. Finish the cut: Continue cutting until you reach the end of the marked line. Turn off the grinder and remove the blade.

Tips and Tricks for Cutting Concrete with an Angle Grinder


 

When using an angle grinder to cut concrete, especially for the first time, it can be a challenge even for experienced DIYers. To make this process easier, here are some tips and tricks:

l Use a steady and controlled motion: Keep the grinder moving at a consistent pace, avoiding jerky or uneven movements that can damage the blade or cause the cut to be uneven.

l Consider investing in an auxiliary grip. This handle accessory can be attached to the angle grinder near its head and gives the user an additional point of contact. This is particularly useful when attempting to smoothly start the angle grinder on a concrete surface.

l Keep the blade cool: To extend the life of the blade and prevent it from overheating, periodically stop the grinder and allow the blade to cool.

l Use water to control dust: Spraying water on the concrete while cutting can help control dust and keep the blade cool.

Summary

Cutting concrete with an angle grinder is a practical and efficient way to make precise cuts in concrete. With the right saw blade and some tips and tricks, you can achieve the best results. The BSP brand offers a range of saw blades designed to handle various cutting applications, including concrete cutting. Whether you're a professional contractor or a DIY enthusiast, BSP diamond saw blades are an excellent choice for your cutting needs.

What are “Coatings”

  T he coatings come up with the overall coverage of abrasive grain particles (such as aluminum oxide or silicon carbide) which are attached to the backing material of coated abrasive product, or rather, how much space is filled or not filled with abrasive grains. The more open space there is between grains, combined with the constant motion from sanding, can lead to a longer abrasive life. As the  sandpaper sheet  is used in a more open coat allows the residue to fall off, thus making it less likely to get stuck in between the grains. Not to mention, the extra space allows more room for air to flow, thereby cooling down the   sanding disc  during the sanding process. Ultimately, with less heat, there will be less opportunity for the wood resins and finish to soften in the first place.   There are three forms of coating options available: open, semi-open and closed - Each type has a different particle ratio and optimal application. Let's take a look at the ...

The Common Problem In Using Diamond Saw Blades

  Diamond saw blades  are an essential tool in a variety of industries, including construction, stone cutting , and glass cutting. They are known for their durability and long lifespan, making them a popular choice among professionals. However, using diamond saw blades is not without its challenges. Here are some common problems that users may encounter when using diamond saw blades: 1.  Blunt edges  of diamond saw blades : One of the most common problems with diamond saw blades is that their edges can become blunt over time. This happens because the abrasive material wears down, causing the blade to lose its cutting power. If you notice that your saw blade is becoming blunt, it is important to replace it as soon as possible to avoid damaging the blade or the material being cut. 2.  Chipping: Chipping is a common problem when cutting tiles , stone or other brittle materials. This occurs when the blade hits an object or material that is harder than the blade itse...
