How to Cut Cinder Block
To cut a cinder block, there are several methods you can use.
One cost-effective way is to use a hammer and chisel.
Measure and mark the desired cut, then place the chisel on the guideline and tap it with a hammer to create scoring lines.
Score across the top of the concrete and then place the chisel in the center and hit it with the hammer to split the concrete.
Another cost-effective option is to use a scoring knife, which works well for cutting cement backer boards.
Measure and mark the desired cut, then place a straight edge beside the guideline and use the scoring knife to run along the guideline multiple times.
Circular saws can also be used to cut small or large pieces of concrete, including blocks, pavers, and walls.
It’s best to use diamond blades with a wet saw for cutting concrete using a circular saw.
Remember to take safety precautions such as wearing hearing protection, gloves, and a respirator, and to properly dispose of any excess concrete from the project.

Did You Know?
1. Cinder blocks were originally called “concrete masonry units” (CMUs) and were developed in the early 1900s as a more cost-effective alternative to traditional stone bricks.
2. The term “cinder” in cinder blocks refers to the ashes and cinders that were initially used as one of the main components of these blocks. However, modern cinder blocks are now made with Portland cement and other aggregates instead.
3. Cinder blocks have excellent thermal properties, making them efficient insulators. They can help regulate temperature, which is why they are commonly used for building walls, as well as constructing fireplaces or ovens.
4. Many people use cinder blocks to create raised garden beds because they provide good drainage and can withstand harsh weather conditions. Additionally, the hollow spaces in the blocks can be filled with soil, allowing plants with deeper root systems to flourish.
5. Cinder blocks have found unique uses outside of construction, such as building furniture. Some creative individuals have turned cinder blocks into outdoor seating, bookshelves, or even coffee tables, demonstrating their versatility beyond their intended purpose.
Method 1: Hammer And Chisel
When it comes to cutting small pieces of concrete, the hammer and chisel method is a cost-effective option. This technique is particularly useful for cutting cinder blocks.
To get started, measure and mark the desired cut on the block.
Next, place the chisel on the guideline and tap it gently with a hammer. This will create scoring lines on the surface of the block. Make sure to score across the top of the concrete, ensuring that the lines are deep enough to guide the subsequent cutting process.
Once the scoring lines are in place, position the chisel in the center of the scored surface and strike it firmly with the hammer. With each hit, the pressure will cause the concrete to split along the scoring lines, resulting in a clean cut.
Steps For Using A Hammer And Chisel
- Measure and mark the desired cut on the cinder block.
- Position the chisel on the guideline and tap it gently with a hammer to create scoring lines.
- Score across the top of the concrete, making sure the lines are deep enough.
- Place the chisel in the center of the scored surface and strike it firmly with the hammer.
- Repeat the process if necessary until the block is cut according to the desired measurements.
Method 2: Scoring Knife
The scoring knife method is a cost-effective option for cutting cement backer boards or similar materials. This method involves using a specialized knife with a sharp but blunt edge to score the surface and create a clean break.
Here are the steps to follow:
- Measure and mark the desired cut on the material.
- Place a straight edge next to the guideline to ensure a straight cut.
- Hold the scoring knife firmly and run it along the guideline multiple times, applying enough pressure to create a visible score line.
- Once the scoring is complete, simply snap the material along the scored line to achieve a clean and precise cut.
Remember, safety is important when working with any tools. Always wear appropriate protective gear and follow proper cutting techniques to avoid accidents.
- Measure and mark the desired cut
- Use a straight edge for a straight cut
- Apply enough pressure to create a visible score line
- Snap the material along the scored line for a clean cut

Circular Saws And Diamond Blades
Circular saws are versatile tools used for cutting small or large pieces of concrete, including blocks, pavers, and walls. To effectively cut concrete with a circular saw, it is recommended to use diamond blades, particularly those designed for wet saws.
Before using a circular saw, it is crucial to ensure proper safety precautions. Protect yourself by wearing hearing protection, gloves, and a respirator to minimize dust inhalation. To mark where you want to cut the cement, use chalk, which provides a clear indication for the saw.
When using a dry saw, it is important to run water over the work area to prevent the spreading of cement dust. It also helps keep the blade cool and prevents it from getting clogged. Additionally, make sure to set the blade depth no more than the depth of each diamond tooth to ensure a smooth and efficient cut.
Angle grinders can also be used to cut through concrete. However, circular saws tend to cut faster and create straighter lines compared to angle grinders. For projects that require cutting a depth of seven inches or more, walk-behind saws are generally recommended. For industrial-sized projects such as cutting through concrete pavement, trenchers are the best choice. Wheel trenchers are particularly suited for cutting through tough terrains like rocky soil or concrete.
Safety Precautions And Permits
Cutting concrete can be a hazardous task, and it is crucial to prioritize safety precautions. Dust emitted from cutting concrete contains harmful silica particles that can lead to lung cancer or other respiratory ailments. Therefore, it is vital to follow safety guidelines provided by organizations such as OSHA.
Obtaining necessary construction permits and preparedness at the worksite are also important steps. Ensuring proper disposal of any excess concrete generated from the cutting process is essential to maintaining a clean and safe environment.
Understanding the different methods and techniques for cutting cinder blocks and other concrete materials can help you complete your project effectively and with precision. Whether using the hammer and chisel, scoring knife, circular saws, or even walk-behind saws and trenchers, following proper safety precautions and obtaining the necessary permits are vital for a successful and secure project. With these essential techniques, you can confidently take on any concrete cutting challenge.
