First of all, a wet-cutting blade needs water; a dry-cutting blade can be used with or without water. Because it doesn’t exist yet, there isn’t a practical way to use water with an angle grinder. Angle grinder dry-cutting diamond blades can be divided into three groups based on the rim’s shape:

Angle grinder concrete cutting segments have a toothed rim that can be utilized to blow away debris and maintain the blade’s coolness. A diamond blade is at risk from overheating because it weakens the bond and may deform.

The greatest option when water is not available is a concrete blade for a segmented grinder. These blades can be used to cut reinforced concrete, limestone, masonry blocks, brick, concrete pavers, and concrete pavers. The industry standard for cutting concrete with an grinder is a diamond blade with a segmented rim.

Diamond blades for turbo rim angle grinders are designed for speed, whether you’re cutting dry or wet materials. The angle grinder disc is cooled by air flowing via the turbo rim’s smaller turbo components.

Using an angle grinder with a continuous rim, you can use diamond blades to cut through marble, granite, porcelain, and ceramic tile. The technique of choice is wet cutting. It is not advised to use a blade with a continuous rim while cutting concrete with an angle grinder.

Types of Angle Grinders and Their Uses

Angle grinders are tools that are used for cutting, shaping and polishing. They are useful for many different kinds of tasks, such as sharpening knives, removing paint from furniture, removing rust from tools and so on.

Angle grinders have a variety of uses. They can be used to cut metal and other hard material such as concrete or stone. This is done by attaching an appropriate disc to the grinder. For example, aluminum oxide grinding discs are usually used for cutting concrete while diamond blade is usually used for grinding metal or stone.

Cutting Techniques with Your Angle Grinder

Angle grinders are versatile tools that can be used for cutting, grinding, and polishing. With the right technique, angle grinders can be used to cut through a variety of materials including metal, stone, and brick.

Different cutting techniques with your angle grinder:

– Cutting metal: use a diamond blade on an angle grinder to cut through metal sheets.

– Stone Cutting: use a diamond blade on an angle grinder to cut through stone tiles or blocks.

– Cutting brick block: use a diamond blade on an angle grinder to cut bricks into smaller pieces.

Cutting concrete blocks with an grinder

Step 1

To decide where to make the cut, measure the concrete block and mark it with a pencil. Across the block’s surface, doodle a horizontal line with a pencil and carpenters square. The markings can be used as a guide while measuring.

Step 2

Protect your face, eyes, and hands by donning a dust mask, safety goggles, and leather work gloves. While cutting concrete blocks, angle grinders produce a lot of dust and debris.

Step 3

Start the angle grinder in step three. Hold the angle grinder with the blade pointed outward and the guard up. As it makes cuts, the blade is made to hurl scraps of chopped material back towards the handle, where the user is standing. The blade will wheel the angle grinder away from the user if it drops or gets stuck in the cut. In this way, the user is secured.

Step 4

Score the concrete block along the pencil-drawn lines using the angle grinder blade. Move the blade back and forth along the pencil line to create a groove that is 1/8 of an inch deep. If you want, apply it to every pencil line.

Step 5

Use the grinder to cut through the concrete block, being careful to follow the score lines. To achieve completely straight cuts throughout the whole surface, start by making parallel cuts along the block’s two boundaries. It’s okay to perform the in-line slash after that. An angle grinder blade should be ran down the center of each score line on a concrete block if you wish to drill a hole in the middle of it. Focus should switch to the four corners of the hole once the blade has been positioned in the middle of the score lines.

Step 6

Turn the concrete block on its side to begin. After finishing cutting the corners on the opposite side of the block, then use the angle grinder to get rid of the waste concrete.

Safety Precautions vs. Actual Machinery Damage

Safety precautions are always to be taken when using machinery. They should be worn at all times, with the correct safety gear for the machine. It is also important to wear safety glasses and gloves to protect your eyes and hands.

Machinery damage can happen if you are not being careful. It is important to wear the correct safety gear, take your time while operating machinery, and think about what you are doing before you start cutting or grinding.

How to use an angle grinder to cut concrete properly

An angle grinder can make quick work of cutting through concrete, but there are a few things to keep in mind before you start. 

  • Check your grip
  • Take precaution
  • Make a cut line
  • Set up your machine
  • Be sure about your grinder

How to use angle grinder properly

Remove any potential trip hazards from the area surrounding you where you will be cutting. Make sure your desk is tidy and clutter-free. If working inside is necessary, make sure there is enough ventilation.

It is required to first mark the location of the line to cut using a straight edge and a pencil or chisel in order to use an angle grinder to make a clean cut. Then, use a chisel to slice the line, making sure the resulting groove is deep enough to hold the blade in place. The blade won’t have to be concerned about slipping that way.

Concrete Cutting problems while using grinder

The ability of an angle grinder to cut through concrete is hardly in question. Its effectiveness will probably be less than a wet, though.

A walk-behind concrete saw’s diamond saw blade is cooled by water that is continuously pushed into the saw; angle grinders do not have this capability. The diamond blade will quickly become dull when cutting anything as hard as reinforced concrete due to the increased friction created by the cutting action.

A manual angle grinder works well to cut through concrete and is sufficient for occasional cutting requirements. Cutting reinforced concrete requires a concrete saw.

Final Verdict

A grinder can be used to improve stamped concrete, reinforced concrete, and even freehand scored decorative concrete. These machines come in larger versions that have a similar appearance but different functions. These tools can be used for both grinding and angular sawing. Putting on the safety guard is a requirement before cutting concrete with an angle grinder. Clear the area surrounding where you will be cutting of any trip hazards.
