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!

What is the best tool to cut concrete?
Use a standard circular saw, equipped with a corundum or diamond blade, for small tasks. For slabs, it’s best to cut through the top inch, then use a sledgehammer to break off the rest. The jagged edge left below the cutting line provides a good rough edge for the new concrete to bond to.
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.
Is it hard to cut concrete?
Wet concrete is very difficult to cut, and fully cured concrete can fracture as it’s being cut. So if possible, cut concrete when it’s hard but only half cured. The cut will come out smoother with less dust.
What kind of blade do you use to cut concrete?

Should I use water when grinding concrete?
The main role of water here is to cool down the diamond tooling and also provide lubrication to reduce friction. Without this lubrication, there is an increased risk of excessive heat generation (from the friction), which will melt the epoxy resin and glaze over the tooling.
How soon can you grind concrete after pouring?
If you’ve opted for a full exposure grind, we recommend grinding the surface about a week after pour, once the concrete has had time to properly settle and establish itself. We’ll then return to seal and polish the concrete at the lockup stage of the project.
How deep can a concrete grinder go?
The key to their versatility are the grinding attachments, which are available in a variety of types and grits to suit different applications. Because grinders use rotary action rather than impact to remove material, the depth of material removal is limited to about 1/8 inch, depending on the type of attachment used.
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.
Can you cut concrete block with a Sawzall?

How deep should I cut my concrete?
A good rule of thumb is to cut the joints one-quarter to one-third the slab thickness. For a 6-inch-thick slab, that means cutting 1 1/2 to 2 inches deep. Ensure that the saw cut depth meets the structural engineering specifications.
