Concrete saws can typically cut up to 10 inches thick but the exact depth will depend on the construction of the saw and what accessories are being used. Most saws are built with specialty blades that can cut up to 15-20 inches thick.
These saws have high-powered diamond blades and hydraulic pressure, allowing them to cut through the concrete efficiently. Some models can even cut up to 30 inches deep. The thickness of the concrete slab should be taken into consideration when making a purchase.
It is also important to consider the depth of the project before making a final decision on the type of saw and blade to be used.

How do you cut 3 inches of concrete?
Cutting 3 inches of concrete requires a few specific items and steps. First, you need a masonry blade for your circular saw. The blade should be at least ¼ inch thick and intended for concrete cutting.
Next, you need to identify a straight line on which to make your cut. This can be done with a laser level or a straight edge. You then need to make a score, or groove, along that line by pressing the blade into the concrete and tracing along the line.
Once the groove is deep enough to hold the blade, you can begin cutting. Make sure to have sufficient ventilation, hearing and eye protection, as sawing concrete can be loud and dusty. Make multiple, shallow passes so the blade doesn’t get too hot and to minimize dust and debris.
Make sure to keep an eye on the depth of the cut, and slow down if the cut is going deeper than 3 inches. Finish with a clean-up pass to achieve a smooth edge. After completing the cut, you may need to chisel out any pieces that didn’t break away.
Is it better to cut concrete wet or dry?
Cutting into concrete involves the use of a power saw with a diamond blade, and whether you should cut dry or wet is largely determined by the type of saw being used. In most cases, wet sawing is the preferred choice when cutting concrete.
Wet sawing uses water to cool and lubricate the diamond blade, minimize the amount of dust created by the cut, and reduce the amount and depth of surface cracking that can occur. For example, when using a circular saw for concrete cutting a steady stream of water is typically applied onto the blade and the area being cut to prevent overheating in order to achieve a better cut.
However, not every job necessitates wet sawing. In some cases where the dust created by cutting concrete is not an important factor, dry sawing may be preferred. Dry sawing eliminates the mess and added complications associated with wet sawing, such as the need to contain and dispose of the used water.
Dry sawing is also typically favored when cutting smaller objects or working in congested areas where wet sawing may be difficult to manage.
Overall, wet cutting is typically a preferred method for cutting concrete because it reduces dust, minimizes surface cracking, and can be easier to manage. However, dry sawing may be the better option in some cases where dust is of little concern or tight work areas make wet sawing difficult to manage.
What happens if you cut concrete too deep?
If you cut concrete too deep, you could cause serious and costly problems. Depending on the size of the area you are cutting, it could compromise the structural integrity of the concrete, throwing off the weight distribution of the slab, and potentially leading to cracking and buckling.
If the cut is severe enough, it could even interfere with the ability of the concrete to carry hydraulic pressure, leading to significant water penetration and damage. Working with a qualified, experienced professional is fundamental to avoiding cutting too deep, as they have the expertise to ensure the job is done correctly.
How deep do concrete relief cuts need to be?
Answer: According to most building codes, concrete relief cuts need to be a minimum of about 1/4 inches deep for interior applications, or about 1/2 inches deep for exterior applications. The exact required depth may vary slightly depending on the concrete mix and local building codes in your area.
It is important that relief cuts are cut at the right depth to provide the proper expansion room for the concrete, as too shallow of relief cuts will result in larger and more visible cracks. In addition to the proper depth, relief cuts should also be placed at regular intervals throughout the slab.
It is generally recommended to place relief cuts at 2-4 foot spacing for interior slabs and 8-10 foot spacing for exterior slabs.
Can you cut concrete with a circular saw?
Yes, it is possible to cut concrete with a circular saw. Doing so requires the use of either a diamond or masonry blade, as regular circular saw blades might not be durable enough to handle the task.
Depending on the type of concrete you are cutting, a dry-cut diamond blade or a wet-cut diamond blade can be used. Specialized blades designed for masonry work can also be used, but they tend to be less efficient than a diamond blade.
When using a diamond blade, it is important to ensure that it is compatible with the specific make and model of your circular saw.
In addition to the correct blade, some other supplies and safety gear will also be needed. Eye protection, dust mask, and ear protection should all be worn to protect you from the particles produced when cutting concrete.
A hammer and chisel are also helpful when making clean, straight cuts in the concrete. When attempting to cut concrete with a circular saw, always use a steady, straight motion and allow the blade to do the cutting.
Don’t attempt to force the blade through the concrete or you may damage the saw and the blade. It is also important to move the saw slowly and to frequently remove dust build up from the surface to maintain a clean cut.
Can you use a circular saw to cut concrete slab?
Yes, it is possible to use a circular saw to cut a concrete slab. In order to do so, you’ll need to first attach a diamond-tipped blade to the circular saw specifically designed to cut through concrete.
Once you have the blade installed, you should make sure you have safety goggles, gloves, and hearing protection. After that, be sure to make sure the area is clearly marked for where you will cut and make multiple passes with the saw, applying light pressure, as this will reduce vibration and deliver a cleaner cut.
Make sure to also keep a steady speed, as cutting too slowly or quickly can cause the blade to heat up resulting in dulling of the blade or can cause cracks in the concrete slab. Additionally, it is a good idea to wet the slab with a hose prior to making the cut to reduce dust and the intensity of the sound.
How thick of concrete can you cut with a circular saw?
The thickness of concrete that can be cut with a circular saw will depend on both the power of your saw as well as the type of blade that you use. Generally, a circular saw with less than 15 amps of power will not be adequate enough to cut through concrete and a wet saw is usually a better option in these cases.
If you have a circular saw with more than 15 amps of power, then the thickness that it can cut through can range from 1. 5-4 inches in concrete. The type of blade used will also affect this as blades that are designed for cutting brick, tile, and block walls, tend to have better cutting abilities than general purpose blades.
It is also important to ensure that the blade is sharp, to ensure the most effective and accurate cutting results.
Can you get a diamond blade for a circular saw?
Yes, you can get a diamond blade for a circular saw. A diamond blade is a saw blade that has a diamond-tipped cutting edge, enabling it to cut through hard materials such as stone, concrete, asphalt, and ceramic tile.
Compared to more standard blades, diamond blades offer a longer life, improved cutting accuracy, and a greater level of precision. Furthermore, they can handle heavier loads while still providing superior cutting results.
When purchasing a diamond blade for a circular saw, make sure you choose one that is compatible with the model of saw you own. Explicit instructions for installation should be provided with each blade, and safety measures should be observed when using any power saw.
How deep do you saw cut a concrete slab?
The depth of a saw cut in a concrete slab varies depending on the purpose of the cut. Generally, when saw cutting concrete slabs for construction purposes, sleeves up to a total depth of 4 inches (100mm) are possible using special blades.
For narrower cut depths of up to 2 inches (50mm) a diamond-tipped concrete saw blade may be needed for greater accuracy. For projects requiring deep saw cuts, core drilling is needed as the cut depth may require up to 12 inches (300mm) or more for certain projects.
Core drilling usually requires the use of a diamond-tipped core drill bit and, if necessary, a vacuum to help contain dust.
