Just how to reduce concrete
An angle grinder is a power device that can be made use of for puncturing various types of materials, including steel and also various other strong products such as bricks, concrete, aluminum, as well as rock
This kind of hand-held power tool does not have a reducing blade yet a grinding wheel Various sorts of discs can be utilized with angle mills for different applications.
Angle grinders can be found in various dimensions. Commonly, they are 10-12 inches in diameter. cut concrete slab angle grinder can be cordless or have a range of motor powers for even more exact work.
In this post, we will go over just how we can reduce different sorts of concrete aspects using the angle grinder and what is the basic procedure of cutting them.
Precautions prior to reducing any sort of concrete.
See to it you are set up for success prior to you begin cutting concrete with an angle mill Safety needs to be your top concern. Use handwear covers for hand security and safety glasses for eye protection.
Guarantee that your angle mill has a functioning security guard around the blade. If you are dry-cutting concrete in order to reduce direct exposure to silica concrete dirt, a face mask will certainly also be required.
Dimension of the grinding wheel.
• You can go approximately 1 to 1 12 inches deep with a 4 12 angle grinder.
• Using a 9-inch angle grinder, you can cut to a depth of 3 to 3 12 inches
A 4.5-inch angle grinder can definitely cut via concrete as much as 1 inch thick, yet you might discover the task is done quicker and with better accuracy if you use a 9-inch angle mill.
An angle mill's motor amps identify its reducing rate. It is normal for a 4.5-inch grinder to have a 7 amp electric motor, whereas a 7 inch or 9-inch mill will have a 13 amp motor.
When cutting concrete with an angle mill, Diamond saw blades are the ideal tool to make use of. An engineered steel core is bordered by synthetic rubies around the side of these blades. Ruby blades are an obvious choice for reducing concrete with an angle grinder, but your alternatives do not quit there.
For reducing and also grinding metals, metal blades are much better. Due to the fact that they reduced slower, discs made of metal are much less efficient on concrete. There are silicon-carbide wheels that can cut with concrete as well as stonework
Cutting concrete slab with an angle mill
It can be much more challenging to puncture concrete that has rebar than concrete alone. The ruby reducing blade is still the very best choice when cutting concrete slabs or decks that are enhanced with steel rebars. See to it to make use of a new ruby blade given that steel will certainly use down the diamonds faster than concrete will.
It is not a task for amateurs to cut concrete with rebar. Concrete reinforced with rebar is extremely solid deliberately and needs extra pressure to puncture. Action where you are reducing as well as stay clear of reducing any kind of channels or energies within the concrete.
Reducing concrete obstructs with an angle grinder
Cinder blocks without rebar are a little bit much easier to cut, however planning is still required. cut concrete pavers should be noted where they are to be cut and also secured down so that you can make an exact cut without the block moving.
In any of these concrete cutting applications, you can pick to cut completely dry or wet. Reducing with water enables for even more specific cuts as well as is less complicated on the blade. Angle grinders are readily available with damp blade reducing adapter kits.
Dry cutting is frequently the much better alternative considering that it doesn't produce the mess that water does, however you will need to manage the dust that this approach creates. Make certain you are putting on the correct air flow mask so you do not inhale silica dirt.
You can use dry-cutting ruby blades with or without water, however wet-cutting diamond blades can only be made use of in wet applications.
Cutting concrete pavers with an angle grinder
Concrete pavers will certainly need that you make a number of cuts through the concrete. After making a few inches of a deep cut, you will certainly sledgehammer or chisel out any type of loose concrete you desire to get rid of, then proceed to cut into the paver until you have actually reached the end.
The basic cutting procedure with an angle grinder

Placing on PPE is the initial step
Concrete cutting is an untidy organization that generates a great deal of debris, including powdered concrete dust. You have to put on the appropriate protective gear prior to dealing with any one of this particles, as it can be hazardous to you.
Mark the concrete.
As soon as you're effectively prepared for the job, order some chalk or a comparable marking utensil as well as begin mapping out where you mean to reduce on the concrete's surface.
Selecting the best blade.
After your concrete has been measured and marked, you will relocate on to the blade selection process, which has been outlined previously.
The Cutting Process
When you've selected your blade, you can terminate up your angle mill as well as begin cutting concrete. After making the cut deeper, you can apply some straight force to take the cut ahead. While cutting, a steady stream of debris might start to fly your method.
Some tips and also tricks for reliable concrete cutting
Even some experienced DIYers may discover it challenging to cut concrete with an angle grinder for the first time. Consider the following tips to make this process also a lot more reliable in order to reduce the knowing curve:
Rating your concrete prior to cutting it. Only plunge your angle mill regarding fifty percent as deep as you desire, as well as job throughout the length of the desired cut.
An extra grasp may work. The second point of get in touch with is offered by these handle devices mounted near an angle mill's head. While considerably grinding into the concrete piece's surface area with your angle grinder, this can be specifically useful.
A plain blade will certainly not be able to make your cuts efficiently as well as need to be replaced. Cut right into concrete surface areas no extra often than needed to stay clear of that.
Final thoughts
You might have believed that reducing concrete with an angle mill would certainly be way too much for that power tool. The process defined above, however, will allow you to accomplish that task rather rapidly. By following the tips detailed above, you can finish your concrete cuts without any kind of included headache or delay.


It can be extra hard to reduce via concrete that consists of rebar than concrete alone. The diamond cutting blade is still the best choice when cutting concrete pieces or decks that are strengthened with steel rebars. Action where you are cutting as well as prevent reducing any type of conduits or energies within the concrete.
Reducing with water allows for even more precise cuts and also is easier on the blade. After making the cut deeper, you can apply some horizontal force to take the cut onward.
