In this article, we will explain some of the most effective methods for cutting concrete blocks without using a saw. We will also provide answers to frequently asked questions and useful tips that you can use when cutting concrete blocks. So, if you’re wondering how to cut concrete block without a saw, read on for all the information you need!
Use a Hammer
The most common way to cut a concrete block without a saw is by using a hammer and chisel. This method requires patience and precision, but it can be done effectively if done correctly. Make sure you use a cold chisel that is designed to work with concrete blocks, otherwise the blade will quickly become dull or break off. To use this method, start by marking the block where you want to make the cut. Then, hold the chisel at a 45-degree angle to the block and hit it with a hammer. Be sure to strike the chisel in short, sharp blows – long swinging strokes can cause cracks.
Use Channel Locks
Channel locks, also known as tongue-and-groove pliers, are a type of adjustable wrench that is designed to grip objects firmly. They can be used to cut concrete blocks without a saw. To use channel locks, make sure the jaws are wide enough to reach the sides of the block and then squeeze them together until it cuts through. It may take some force to cut through the block, but you should be able to get the job done. Be sure to wear protective gloves and goggles when using channel locks, as they can cause serious injury if used incorrectly. Once finished, clean off any concrete dust with a shop vacuum or brush.

Use a Car Jack
Using a car jack is an excellent way to cut through concrete blocks without the need for a saw. Start by making sure your block is securely held in place on a flat surface such as a work bench or table. Place the blade of the car jack directly onto the area you want to cut and begin slowly squeezing the handles together until the blade cuts through. This method is one of the most effective ways to cut concrete blocks without a saw.
However, it does require more strength than using a saw and can be a bit time consuming. Make sure to take your time with this method as rushing could result in an uneven cut or damage to the block itself. Additionally, you will need to dispose of any dust created by the car jack as it may contain small particles of concrete. [1]
Cut It Off With Wire Cutters/Clippers
Wire cutters and clippers are great tools for cutting concrete blocks without a saw. They can be used to cut through the block in straight lines or even curves, depending on your needs. Be sure to wear protective gear like eye goggles and gloves when using wire cutters, as it can be dangerous if not handled properly.
Start by marking the area that you want to cut. Then position the clippers or wire cutters at one end of the line and press down firmly while moving it along the line in a slow, steady motion. It will take some time to get through the block, but eventually you should be able to make it all the way through without any major problems. [1]
Use an Angle Grinder/Disc Cutter
An angle grinder or disc cutter is an electrical tool designed for cutting metal and stone surfaces. It consists of a motor that drives an abrasive wheel or disc, allowing it to cut through the material with ease. An angle grinder can be used to cut concrete blocks quickly and accurately without making a mess.
When using an angle grinder, ensure that you wear the recommended safety gear. Make sure to wear protective eyewear and a dust mask, as concrete dust can be very hazardous when inhaled.
You’ll also need an appropriate diamond-tipped blade for your angle grinder. Diamond blades are specially designed to cut through stone and concrete without becoming dull too quickly. Make sure that the size of the blade is appropriate for the angle grinder you’re using. [3]
Use a hacksaw
A hacksaw is an inexpensive and easy to use tool for cutting concrete blocks without a saw. It may be a little slower than using a power saw, but it will still get the job done quickly and accurately. You’ll need to have a fine-toothed blade with lots of sharp teeth that can cut through the concrete block easily. To use this method, you’ll need to make sure the hacksaw blade is firmly held in place in the handle. Then, position the blade against the surface of the block and move it back and forth across the cut line. Make sure to keep a steady pressure on the saw so that it doesn’t move too quickly and create an uneven cut. [3]
Cut With Duct Tape/Cable Ties
The simplest and most cost-effective way to cut a concrete block without a saw is using duct tape or cable ties. Start by marking the line you want to cut, then wrap the duct tape or cable tie around the block where you want it to be cut. Securely fasten the ends together until they are tight enough that it won’t slip off. Next, use a hammer or mallet to tap along the length of the tape or cable tie until it breaks through. Once you’ve made enough taps with the hammer, your cut should be done.
This method is simple and doesn’t take up much time but it may not be as precise as other methods, so make sure to use a tape measure to double-check your results. [3]
Tin Snips
Tin snips are a great tool to cut concrete blocks without a saw. They work best on thin sections of the block, and can be used to make straight cuts or curved cuts in the material. To use tin snips, start by marking your desired shape onto the block with a pencil or marker. Then, use the tin snips to cut along the marked line. Make sure to wear safety glasses and work gloves when using tin snips, as the blades can be sharp and cause injury if not handled with care. [3]
Cordless Drill and MAPP Gas Torch
A cordless drill is the most popular and useful tool for cutting concrete blocks without a saw. It can be used to score a line on the block, creating a groove that allows you to easily break it apart into two separate pieces. In order to use this method, make sure you have a battery-powered drill with a masonry bit. This type of bit has a special diamond-tipped blade that can cut through concrete.
You will also need to purchase MAPP gas, which is a type of fuel that is used in torches. This gas is very hot and will allow you to make precise cuts when cutting the block. Be sure to wear safety glasses and gloves when performing this procedure as it can be dangerous if not done properly.
If you are unsure of how to use the drill and MAPP gas torch, there are plenty of tutorials available online that can provide guidance on how to correctly do it. With the right tools and some patience, this is a great way to cut concrete blocks without a saw. [3]
Rotary Tool
A rotary tool is a versatile power tool that can be used to cut concrete blocks without a saw. It works by using an abrasive material, such as sandpaper, diamond-tipped blades, or grinding and polishing stones, to wear away at the block until it is cut through. This method is slower than using a saw but will still give you clean, precise cuts.
To use a rotary tool to cut concrete blocks, you will need the following items:
- Rotary tool with an abrasive attachment
- Safety glasses & gloves
- Work surface or saw horses
- Marker or pencil for marking the block
- Dust mask for cutting indoors
- Goggles for cutting outdoors
- Waterproof sealer (optional) [3]
Reciprocating Saw
If you need to cut into a concrete block without a saw, the best option is to use a reciprocating saw. This power tool has long blades that can effectively cut through masonry materials such as brick and cinder block. A reciprocating saw is relatively easy to operate, includes an adjustable blade guard for safety, and requires minimal setup time.
Pliers and Pincers
Pliers and pincers are great tools when it comes to cutting concrete blocks without a saw. If you’re going to be using this method, make sure that the pair of pliers or pincers you choose have very strong jaws. You can use these tools to grab onto a concrete block and slowly work your way through it until it’s broken apart. This technique tends to be a bit slower and can cause more dust, but it’s an effective way to get the job done.
When using pliers or pincers, you’ll want to wear gloves so that your hands don’t get sore from gripping the tools for too long. Additionally, you should take care not to chip or break any pieces off the block when attempting to break it apart. [2]
Use a Dremel
If you don’t have a masonry saw, a Dremel saw is a great alternative to cutting concrete blocks without using a saw. It’s best for smaller jobs since it can cut at slower speeds and doesn’t generate as much dust. To use the Dremel saw, attach the appropriate cutting wheel specifically designed for brick, concrete or stone. Place the block on a work surface and use a marker to draw your lines. Put on safety goggles (and a dust mask if needed) before you start cutting and make sure the wheel is spinning at full speed before putting it in contact with the concrete. To begin cutting, score the line lightly by pressing firmly enough that sparks will appear as you cut. Once the line has been scored, increase the pressure slightly and continue to cut through the block. Make sure to keep the wheel moving as you go and don’t stop until you have finished cutting all the way through the concrete. [2]
Use a Propane Torch and Hacksaw
Using a propane torch and hacksaw is one of the most effective methods for cutting concrete blocks without a saw.
The first step is to attach an oxy-acetylene torch tip to a filled tank of propane, then light it using a striker or lighter. Once lit, place the torch at the spot on the block where you want to make the cut and begin to slowly move it along the line. The intense heat of the torch will melt away the concrete, making it easier to break apart with a hacksaw.
Make sure to keep your hands and face at least 3 feet away from the flame while cutting. It’s also important to wear safety goggles, heavy gloves, and long sleeves in order to protect yourself from the intense heat and flying debris.
Once you’ve heated the concrete block to a sufficient temperature, use a hacksaw to cut through the softened material. This may take some time, so be patient! Depending on the thickness of your block, it can take 10-15 minutes for a full cut. [2]
Use a Cutting Torch
A cutting torch is a great way to cut concrete blocks without a saw. This tool uses the heat generated by an oxygen-acetylene flame to cut through thick materials like concrete blocks. You can pick up an oxy-acetylene cutting torch from your local hardware store or rental center, and it should come with all of the necessary equipment. Be sure to read the instructions carefully before use.
When using a cutting torch, safety is paramount. Make sure you have the proper protective gear such as eye protection and thick gloves to protect yourself from sparks and heat. Make sure your work area is well ventilated, as the fumes created by burning concrete can be dangerous. Once all safety precautions are taken, light the torch, adjust the flame size, and start cutting. Move slowly but steadily along the line you’ve determined is your cut. [2]
Use a Shim
If you don’t have a saw to cut through your concrete block, there are still ways to get the job done. One such option is using a shim. A shim is simply a thin piece of metal or wood that can be inserted between two pieces of material. When it comes to cutting through the block, using a shim involves placing the shim at the desired cut location and then tapering it with a hammer or chisel. Once the shim is in place, you can use a saw or another cutting tool to finish the job.
Be sure to use safety precautions when using a shim as it can cause serious injury if used improperly. Additionally, be mindful of which type of material you are using for the shim. Some materials, such as metal, may not be suitable for your job due to their hardness and potential to cause damage or harm. [2]
