Concrete cutting is a common task at the construction area, such as cutting concrete floor, concrete wall, concrete slabs and concrete pavers. Although the various concrete cutting saw is available, an angle grinder is the most convenient tool for small concrete cutting work. Finish the corner cuts and trim any excess concrete from the cut with the angle grinder on the reverse side of the concrete block.
The amps in the motor of the angle grinder determine how fast the grinder will cut. Cutting concrete with an angle grinder is always best done with a diamond saw blade. Choosing a diamond blade for cutting concrete with an angle grinder is a no-brainer, but your options do not stop there.
Once you have your blade picked out, you can kick on your angle grinder and begin the concrete cutting process. Cutting concrete with an angle grinder for the first time can be challenging for even some experienced DIYers. You may have come into this thinking that cutting concrete with an angle grinder would be a bridge too far for that productive power tool.
Concrete cutting is a common task at construction area, such as cutting concrete floor, concrete wall, concrete slabs and concrete pavers. Although various concrete cutting saw are avalible , angle grinder is the most convenient tool for small concrete cutting work. If your concrete cutting work are really occasional, a manual angle grinder works fine for light-duty cutting work.
In order to ensure that you correctly use an angle grinder when cutting concrete, it is necessary to take several aspects into account. Prior to using the angle grinder, try it out for grip and test the weight to ensure that you can handle it. Small particles of concrete can come loose and fly off during the cutting process, which can present a real hazard.
1) Continuous Rim:Obviously the most gentle method of cutting since there are effectively no “Teeth”. Therefore best for high-quality cutting of Ceramic Tiles – WET or DRY. The Pro’s use them DRY on small Angle Grinders to cut notches and stuff out of Ceramic Tiles, but you also see them on all of the powered Tile Saws that run WET. The penalty of this gentle cutting is that they are too slow for thicker material, which is why you instead see the Segmented-type disks in the dedicated WET Stationary Brick Saws…Wouldn’t even bother trying to use a Continuous to cut Concrete with. Might be okay going through the Mortar Bedding under some tiles on the Bathroom floor, but Concrete is a different kettle of fish…. 2) Segmented:As alluded to above, these are more aggressive than the Continuous Rim, due to the notches that effectively act the way that Teeth and Gullets do in normal saw blades for timber.
Turn the angle grinder on and allow the disc to reach full speed before setting it down on the concrete surface to achieve smoother and better results. Yes, using an angle grinder to cut concrete has a few disadvantages, but they’re mainly related to leveling and grinding a concrete floor. Thank you for reading our post on how to cut concrete with an angle grinder! Angle grinders are extremely versatile tools, and even though they weren’t primarily designed with concrete in mind, they can become a great ally for the handyman who needs to do occasional and small concrete cutting work.

A high concentration of silicon carbide grain helps this DEWALT 4-1/2 in. Concrete/Masonry Grinding Wheel aggressively shave down brick, marble, block, stone, mortar and other masonry. It’s constructed with three full sheets of fiberglass for utmost resilience and grinding power in pulverizing stonework.
How deep can a concrete saw cut?
They can cut through 12 to 14-inches of concrete. It is wise to use a strong power source for cut-off machines to increase their speed. They also become simpler to use and are less noisy. This is even more so if the main focus is on the depth of the cut as opposed to the noise created when in an enclosed environment.
How much will a concrete grinder remove?
How much will a concrete grinder remove? A grinder can take off up to 1/8 of an inch of material with each pass — less than a concrete scarifier, which cuts into surface coatings and the underlying concrete and can cut about 1/4 of an inch with each pass.
How do you cut concrete by hand?
Use your dominant hand to grip the back handle and push the blade forward and backward. Begin cutting at the edge of the concrete and slowly follow the chalk line. Don’t press the blade into the ground—let the weight of the blade and saw do the work. Remove the blade every 30 to 45 seconds to avoid overheating.
How long do concrete grinding wheels last?
It may be true under ideal storage conditions Resinoid Bonded grinding wheels can survive without any degradation in strength for well over two years.
How do you use a diamond cup grinding wheel on concrete?
When grinding concrete, the bond of the diamond cup wheels should normally be the opposite of the concrete, ie use a soft bond on hard concrete, and a hard bond on soft concrete. Use a larger diamond grit (lower number) for faster removal of concrete and for harder concrete.
Is it hard to grind concrete?
Concrete grinding is actually a lot easier than I thought it was going to be. Obviously, this depends so much on what you are trying to do and the circumstances, but the basic operation of the machines was easier than expected.
