Can You Cut Concrete With a Chisel
Yes, you can cut concrete with a chisel.
While a jackhammer or hammer drill is typically needed for most concrete demolition projects, a cold chisel can be used in small areas or for cleaning up edges.
The cold chisel, a small pointed piece of metal, can make precision cuts in concrete when used correctly.
It is a cost-effective choice for cutting small pieces of concrete.
Safety precautions such as wearing hearing protection, gloves, and a respirator are essential.
Using a wet saw and spraying water on the work area helps prevent the spread of cement dust.
Chalk can be used to mark where the concrete should be cut, and the depth of the blade should be adjusted based on the thickness of the concrete.
While circular saws with diamond blades are suggested for cutting concrete slabs, pavers, blocks, and walls, angle grinders can also be used.
For larger projects, a walk-behind saw is recommended.
Did You Know?
1. Chisels can indeed be used to cut through concrete, but it requires a special type known as a masonry chisel. Its sturdy, tempered steel blade and wider cutting edge are designed specifically for such tasks.
2. The process of cutting concrete with a chisel is commonly referred to as “scoring.” Scoring involves making shallow, controlled cuts along the surface of the concrete to create a weak point where it can be easily broken.
3. Concrete cutting with a chisel is not a new technique; in fact, ancient civilizations like the Romans and Egyptians used chisels to shape and cut stone, including concrete-like materials such as limestone or sandstone.
4. When cutting concrete with a chisel, it is crucial to wear protective gear such as safety goggles and gloves, as the process can produce sharp debris that may cause injury. Additionally, ear protection may be necessary due to the noise generated.
5. If you find yourself needing to cut through a large volume of concrete, it is recommended to use a specialized power tool such as a rotary hammer drill with a masonry chisel attachment. This method is not only more efficient but also prevents unnecessary strain on the hands and arms.
The Use of Chisel for Cutting Concrete
When it comes to cutting concrete, jackhammers or hammer drills are usually the first tools that come to mind. However, in certain situations, a chisel can also be a useful tool for this task. While a jackhammer or hammer drill is typically required for most concrete demolition projects, a cold chisel can be utilized in small areas or for cleaning up edges.
A cold chisel is a small, pointed piece of metal that can make precision cuts in concrete when used correctly. It is an effective tool for making small cuts or removing thin layers of concrete. When using a chisel, it is essential to have a steady hand and the right technique to achieve the desired results.
Two Methods for Cutting Concrete
There are two commonly used methods for cutting concrete: the hammer and chisel method and the scoring knife method.
The hammer and chisel method is a cost-effective option suitable for cutting small pieces of concrete. It involves using a hammer to strike the chisel and create cuts in the concrete. This method requires precision, control, and patience, particularly when working with larger pieces of concrete.
The scoring knife method, on the other hand, is a cost-effective choice for cutting cement backer boards. This method involves using a scoring knife to make a shallow cut along the desired line. Once the score is made, pressure can be applied to snap the board cleanly along the line. This method is efficient and allows for clean cuts, especially when working with cement backer boards.
Safety Precautions for Cutting Concrete
Safety should always be a top priority when working with concrete and cutting tools. Before starting any concrete cutting project, it is essential to equip oneself with the necessary safety gear. This includes wearing hearing protection to combat noise from power tools, gloves to protect the hands, and a respirator to filter out harmful dust particles.
To prevent the spread of cement dust, it is recommended to use a wet saw and spray water on the work area. This helps to control the dust and lessen its impact on the surrounding environment. Another safety precaution is to mark the area where the concrete should be cut using chalk. This provides a clear guideline to follow and ensures accurate cuts.
Tools for Cutting Concrete
Several tools can be used for cutting concrete, depending on the size and complexity of the project.
-
Circular saws with diamond blades are suggested for cutting concrete slabs, pavers, blocks, and walls. These saws provide efficient cutting, and diamond blades offer durability and precision.
-
Angle grinders can also be utilized for cutting concrete, although circular saws are generally faster and create straighter lines.
-
For larger projects, a walk-behind saw is recommended. These powerful machines are designed specifically for cutting concrete slabs and provide more control and stability.
-
For industrial-sized projects like cutting through concrete pavement, trenchers are the best option. These heavy-duty machines can handle large-scale cutting with ease and efficiency.

Tips and Considerations for Cutting Concrete
When cutting concrete, there are a few tips and considerations to keep in mind:
-
Adjust the depth of the blade based on the thickness of the concrete. This ensures a desired depth without damaging the underlying structure.
-
Use step cutting technique to create deep cuts. This involves making multiple cuts at different depths until the desired depth is achieved. It provides more control and reduces the risk of cutting too deep in a single pass.
-
Follow safety guidelines and take precautions to protect against silica dust exposure. This includes wearing a respirator and adhering to OSHA guidelines.
-
Dispose of excess concrete properly according to local regulations to minimize environmental impact.

Frequently Asked Questions
What is the best tool to cut concrete with?
When it comes to cutting concrete, the best tool to rely on is a diamond blade concrete saw. Diamond blades are specifically designed to handle hard materials like concrete, bricks, and tiles with precision and efficiency. These saws use the abrasive properties of diamond as the cutting edge, allowing them to make clean and precise cuts through even the toughest surfaces. With a diamond blade concrete saw, you can trust that your cutting tasks will be carried out smoothly, ensuring the desired outcome in the construction industry.
Can a metal chisel cut cement?
Yes, a metal chisel can cut cement, although it may not be the most efficient tool for the job. While a cold chisel can be used for masonry work, chisels specifically designed for cutting stone, concrete, or brick are generally more effective. Mason’s chisels, such as the brick chisel or brick bolster, are equipped with wide spade bits that allow for even chopping of bricks. Using these specialized chisels can ensure better precision and make the cutting process easier and more efficient.
What is the best chisel to break up concrete?
The best chisel to break up concrete would be the Dasco Pro 3/4 in. x 12 in. Concrete Chisel. Specifically designed for breaking up concrete floors, sidewalks, and paving slabs, it offers practicality in situations where an air hammer would be impractical. The chisel’s target guard provides added protection for your hand, preventing glancing blows and missed hits from causing harm. With its durability and design, this chisel is the ideal tool for effectively breaking up concrete.
Can cold chisel cut concrete?
No, cold chisels are not designed to cut concrete. While they may be used by some people to chip concrete and break bricks, these tasks should ideally be done with a masonry chisel, which is specifically designed for such purposes. Cold chisels are best suited for shaping and cutting cold metals. Misusing and neglecting a cold chisel in tasks such as prying or scraping paint can lead to its accelerated wear and eventual disposal.
