How To Cut Cinder Block Reciprocating Saw
When it comes to cutting cinder block, a reciprocating saw can be a handy tool to have in your arsenal. Whether you’re looking to create a window or door opening, or you simply need to remove a section of cinder block for a project, a reciprocating saw can make the job quick and easy.
Before you begin cutting, it’s important to ensure you have the proper safety gear. This includes safety glasses to protect your eyes from any flying debris, as well as gloves to protect your hands. Additionally, you’ll want to make sure your work area is clear of any obstructions and that you’re working on a stable surface.
Once you’re ready to start cutting, it’s important to choose the right blade for the job. For cutting cinder block, a masonry blade is your best bet. This type of blade is specifically designed to cut through tough materials like cinder block and concrete. Make sure the blade is securely attached to the reciprocating saw before you begin.
When cutting, it’s important to use a slow and steady motion. Apply light pressure to the saw and let the blade do the work.

After you’ve finished cutting, make sure to turn off the reciprocating saw and allow the blade to come to a complete stop before removing it from the cinder block. Clean up any debris and dispose of it properly. With these tips in mind, you’ll be able to successfully cut cinder block with a reciprocating saw and tackle your next project with confidence!
Choosing the Right Blade
When it comes to using a reciprocating saw to cut cinder blocks, choosing the right blade is crucial. The blade you use can make a significant difference in the speed and efficiency of your cuts, as well as the quality of the finished product.
First and foremost, you need to consider the material you will be cutting. Cinder blocks are made of concrete, so you will need a blade specifically designed for cutting through this tough material. Look for a blade that has carbide or diamond grit, as these materials are known for their durability and ability to cut through concrete.
The length of the blade is also important. Reciprocating saw blades come in various lengths, and the right length will depend on the depth of your cinder block. You want a blade that is long enough to cut through the entire block in one pass, but not so long that it becomes difficult to handle or control.
Another factor to consider is the teeth per inch (TPI) of the blade. Blades with a higher TPI are more suited for cutting through harder materials, such as concrete, while blades with a lower TPI are better for softer materials. For cutting cinder blocks, a blade with a TPI between 8 and 12 would be ideal.
Lastly, always ensure that the blade you choose is compatible with your reciprocating saw. Different saws have different blade mounting systems, so make sure the blade you purchase fits your saw securely and properly.
By taking the time to choose the right blade for cutting cinder blocks with a reciprocating saw, you can ensure that you achieve clean, precise cuts and make the task much easier and more efficient.
Preparing the Work Area
Before you begin cutting a cinder block with a reciprocating saw, it’s important to prepare your work area to ensure safety and efficiency. Follow these steps to get started:
- Gather your tools: Make sure you have all the necessary tools and equipment for the job. This includes a reciprocating saw with a masonry blade, safety glasses, gloves, a dust mask, and hearing protection.
- Choose a suitable location: Find a well-ventilated area with enough space to maneuver the cinder block and the reciprocating saw. A clean and flat surface is ideal.
- Clear the area: Remove any debris, clutter, or obstacles from the work area. This will reduce the risk of accidents and ensure a clean and organized workspace.
- Protect the surrounding area: Cover nearby surfaces or objects with a drop cloth or plastic sheeting to prevent dust and debris from spreading. This will make cleanup easier and protect your belongings.
- Put on safety gear: Before you start cutting, put on your safety gear including safety glasses, gloves, a dust mask, and hearing protection. This will protect you from potential hazards such as flying debris and excessive noise.
- Create a guide: Use a straightedge or a chalk line to mark the cutting line on the cinder block. This will help you make precise and accurate cuts.
By following these steps, you’ll ensure a safe and organized work area for cutting cinder blocks with a reciprocating saw.
Aligning and Marking the Cut
Before you start cutting the cinder block with a reciprocating saw, it is important to properly align and mark the area you want to cut.
First, measure the length and width of the cinder block where you want to make the cut. Use a tape measure for accurate measurements.
Next, use a pencil or marker to mark the cutting line on the cinder block. Make sure the line is straight and aligned with your measurements.
To ensure a clean and precise cut, it is recommended to use a straightedge or a level along the marked line. This will help you maintain a straight and accurate cutting path.
Additionally, you can use a clamp to secure the cinder block in place while cutting. This will prevent it from moving and ensure a more controlled and accurate cut.
Remember to wear safety goggles and gloves before starting the cutting process to protect yourself from any debris or splinters.
Once you have aligned and marked the cut, you are ready to start cutting the cinder block with a reciprocating saw.
Cutting the Cinder Block
When it comes to cutting cinder blocks, a reciprocating saw, commonly known as a sawzall, can be a great tool to use. Here are the steps to cut a cinder block using a reciprocating saw:
Step 1: Safety first
Before you begin, make sure you are wearing the necessary safety gear, including safety glasses and gloves, to protect yourself from any potential hazards.
Step 2: Mark the cut
Use a measuring tape and a pencil to mark the desired cut on the cinder block. Ensure that the line is straight and accurate for a precise cut.
Step 3: Prepare the reciprocating saw
Attach a masonry cutting blade to your reciprocating saw. Make sure the blade is securely fastened to the saw before proceeding.
Step 4: Position the cinder block
Place the cinder block on a stable surface, such as sawhorses or a workbench. Be sure to clamp the block down securely to prevent any movement during the cutting process.
Step 5: Start cutting
Hold the reciprocating saw firmly with both hands and position the blade right on the marked line. Apply steady and even pressure as you guide the saw along the marked line, allowing the blade to do the cutting. Take your time and let the saw do the work.
- If you are cutting through a solid cinder block, it may be best to cut from both sides of the block to prevent any chipping or damage.
- Ensure that you are cutting at a slow and controlled speed to maintain accuracy and prevent the blade from overheating.
Step 6: Finishing touches
Once you have made the cut, inspect it to ensure it is clean and straight. If needed, use a masonry file or a piece of sandpaper to smooth out any rough edges or imperfections.
Remember to always follow the manufacturer’s instructions and safety guidelines when using power tools. Practice proper safety precautions and take your time when cutting cinder blocks to achieve the best results.

2. Smooth the edges
Using a sanding block or sandpaper, gently smooth the cut edges of the cinder blocks. This will help reduce any roughness or unevenness caused by the cutting process. Take care not to sand too aggressively, as it may damage the surface of the cinder blocks.
3. Seal the edges
Applying a sealer to the cut edges of the cinder blocks can help prevent moisture absorption and extend the longevity of the blocks. Choose a sealer that is specifically designed for masonry surfaces and follow the manufacturer’s instructions for application.
4. Apply a finish
If desired, you can apply a finish to the cinder blocks to enhance their appearance. Options include painting, staining, or applying a decorative coating. Make sure to use a finish that is suitable for masonry surfaces and follow the manufacturer’s instructions for application and drying times.
