Can you cut concrete too deep?
Depth of Cut In case the cut is too deep, the interlocking may not be sufficient enough for transfer of loads. On the other hand, if it's too shallow, it might result in random cracking. The contractor should also make sure that the concrete cut depth meets the appropriate structural engineering specifications.
Does cutting concrete weaken it?

What type of saw blades are used for concrete?
There are two categories of concrete blades for circular saws: abrasive corundum masonry and diamond blades. Corundum (hard aluminum oxide) blades cost less and cut through concrete, asphalt and stucco, but they are not very fast. They can only make shallow cuts of 1/4 to 1/2 inch deep, so you need to cut into the surface repeatedly. Besides that, these blades wear down quickly, create fine dust and get hot enough to glow. They also smell. If you only need to create a few shallow cuts, abrasive corundum masonry blades are the more economical choice.

What is a circular saw?
A circular saw would be a power tool that uses an abrasive or a toothed disc to cut various materials by utilizing the motion spinning around its arbor. It can cut materials such as masonry, metal, plastic, and wood, and can be either mounted to a machine or hand-held. The blades of these devices are specially designed for the material they are intended to be used on and can be powered by electricity, gasoline, or a hydraulic motor. The circular saw first appeared somewhere at the end of 18th century when it was used to transform logs into timber. There are many claimants to the invention of this device, but the person most commonly accepted as its inventor is Samuel Miller, who obtained a patent all the way back in 1777. The rotary nature of this handy device requires more power to operate – but it’s highly efficient since its teeth are in perpetual motion. The sound of this machine is different than that of the up-and-down saw, which is precisely what earned it the nickname of the buzz-saw.

How Deep Should the Cut Be?
In our experience, a good rule is to always cut the joint 1/4 to 1/3 of the piece’s thickness. Always check that the depth of the cut is sufficient enough and that it’s according to the recommendation of the engineer. If it’s too deep, the interlocking simply won’t be enough for the transfer of the loads. If it’s too shallow, there’s a great chance for the random cracks to occur. Factors like slab thickness and length, base type, and the curing techniques all need to be analyzed before choosing where to cut the joints.
How much does a 7 inch blade cost?
These types of blades are typically quite inexpensive – a 7″ blade will cost you under $5. They are widely available and can be used for cutting asphalt, stucco, as well as concrete. Unfortunately, the low price of abrasive corundum blades has a negative effect on their speed, as they’re capable of cutting only the shallow 1/2″ to 1/4″ passes. Cutting with them can be quite time-consuming, and they also wear away fairly quickly.
