Use a Dremel rotary tool with a reinforced cutting wheel
Using a Dremel rotary tool with a reinforced cutting wheel is an effective way to cut nails stuck in cement. The Dremel MM485 Carbide Flush Cut Oscillating Tool Blade is a popular choice for this task, with its carbide technology that enables cutting through even the toughest materials, including nails, hardened steel, and cement.
To ensure safety and efficiency when using the Dremel rotary tool, follow these steps:
- Put on appropriate safety gear, including eye protection, hearing protection, and a particle mask to safeguard against flying debris, sparks, and cement dust.
- Select the appropriate Dremel attachment for cutting nails. The reinforced cutting wheel is suitable for this task, but you can also explore other options like the carbide rasp or grout removal blades offered by Dremel.
- Firmly hold the Dremel tool and position it close to the nail head, ensuring that the cutting wheel is aligned with the nail.
- Start the tool and allow it to reach its full speed before proceeding.
- Gently apply pressure to the nail, letting the cutting wheel grind through the nail. Take your time and avoid forcing the tool too aggressively, as this can damage the wheel or the surrounding cement.
- As you cut, be mindful of sparks generated by the tool. While the sparks are typically not a significant fire hazard, they can be a safety concern if they come in contact with your eyes or flammable materials nearby.
- Once the nail is cut, inspect the area for any remaining nail stubs and use the Dremel tool to smooth out any rough spots.
Remember to always follow the safety guidelines and instructions provided by the manufacturer when using power tools like the Dremel rotary tool. Additionally, consider renting the tool if you don't anticipate frequent use, as it may be more cost-effective than purchasing one.

Wear safety gear to protect against sparks
When using a Dremel tool to cut nails stuck in cement, it is important to take the necessary safety precautions to protect yourself from sparks and other potential hazards. Here are some detailed guidelines to follow:
Wear Protective Gear
Personal protective equipment (PPE) is crucial when working with power tools like Dremel. Always wear sturdy safety glasses or shields to safeguard your eyes from flying sparks, debris, and concrete dust. This is especially important when cutting nails, as the grinding process will generate sparks and dust. Additionally, consider using a dust mask to prevent the inhalation of concrete dust, which can be harmful to your lungs. Ear protection is also essential, as power tools can be loud, and prolonged exposure to high-decibel sounds can lead to hearing damage.
Create a Safe Work Environment
Before starting, ensure your work area is clean, well-lit, and free from clutter. A tidy workspace reduces the risk of accidents and provides easy access to your tools and safety equipment. Keep bystanders, children, and visitors away from the work area to avoid distractions that could lead to loss of control. Check for adequate ventilation to minimise the inhalation of potentially dangerous vapours and concrete dust. If possible, work in a dedicated workshop or outdoors with good airflow.
Understand Your Tool and the Task
Take the time to read and understand the manufacturer's guidelines and instructions provided in the Dremel tool manual. This will ensure you are using the tool correctly and safely. Additionally, be mindful of the potential hazards associated with the task. When cutting nails with a Dremel tool, be aware that the cutting wheel will generate sparks, and grinding the concrete will produce a significant amount of dust. This knowledge will help you prepare and take the necessary precautions, such as wearing the appropriate PPE.
Clothing and Hair
Consider your clothing and hair when using power tools like Dremel. Untied hair or loose clothing can pose a serious risk of entanglement in the tool's moving parts. Always tie back long hair and secure any loose clothing items before beginning your project. This simple step can help prevent accidents and ensure a safe working environment.
Avoid Explosive Atmospheres
Never operate your Dremel tool in the presence of flammable liquids, gases, or excessive dust. Power tools, including Dremel, create sparks, which could ignite these substances and lead to a dangerous explosion. Always be mindful of your surroundings and the potential hazards before starting your work.

Use a cutoff wheel or grinder for smooth results
If you want a smooth finish, a cutoff wheel or grinder is the way to go. You can use a Dremel rotary tool with some grinding discs to cut the nails, but for a smooth finish, a cutoff wheel attachment is required. This method will produce sparks, so it is important to take the necessary safety precautions. If you are concerned about the sparks, you could use a false ceiling as a barrier.
A grinder will allow you to grind away some of the concrete around the nail, so the nail is below the surface. You can then patch over the nail to create a smooth, level surface. A 4" grinder with a skinny blade will do the job. If you are looking for a flush cut, a grinder with a cutoff disk will be required. You can rent a grinder if you don't want to purchase one.
If you are using a Dremel tool, make sure to use a reinforced cutting wheel attachment. This will also produce sparks, but they are typically not hot enough to burn your skin or wood. However, if you have any flammable materials nearby, you should exercise caution.
If you are cutting many nails, a Dremel tool may not be the most efficient option, and a larger cutoff wheel may be preferable.

Drill a hole and hammer wood to lift the nail
Drilling a hole and hammering wood to lift a nail stuck in cement is a viable option. Here is a step-by-step guide to help you with the process:
Step 1: Prepare the Necessary Tools and Safety Gear
Before you begin, ensure you have the right tools and safety equipment. You will need a hammer drill, a framing hammer, concrete nails, hearing protection, eye protection, and a particle mask. The hammer drill and framing hammer are essential for this task, as they are designed for drilling into concrete and driving concrete nails.
Step 2: Drill Pilot Holes
Start by drilling pilot holes through the wood and into the concrete using the hammer drill. Ensure that the drill bit is the same diameter or slightly smaller than the nails you will use. Drill the holes to the proper depth for the nails, being careful not to penetrate the concrete completely. This step will create a guide for the nails and make it easier to drive them in.
Step 3: Hammer the Nails
Place the wood over the pilot holes, aligning it with the marks on the concrete. Use concrete nails, which are made of high-grade carbonated steel and designed for projects requiring nailing into concrete or other hard materials. Drive these nails through the wood and into the pilot holes using the framing hammer. Make sure the nails are flush with the surface of the wood.
Step 4: Reinforce the Bond (Optional)
If you want to strengthen the bond between the wood and concrete, you can use construction adhesive. Run a bead of construction adhesive along the bottom of the wood before positioning it and driving in the concrete nails. This step will create a stronger hold between the two surfaces.
Step 5: Lift the Nail
Once the nail is secured in the wood, you can use the hammer to lift and remove it from the cement gently. The wood will provide leverage and help you pull the nail out without causing further damage to the surrounding concrete.
Remember to take appropriate safety precautions during the process, including wearing protective gear and being cautious of any flying nail or concrete shards.

Use a pry bar to pull out the nail
If you are looking to remove nails stuck in cement, a pry bar can be a useful tool. Pry bars are heavy-duty tools for extremely tough nails. They are L-shaped lengths of metal with a flat chisel on one end.
To use a pry bar, place the flat end of the straight side under the head of the nail. Hold the bar in the middle using your non-dominant hand. Then, hammer the bar down on the opposite end to pop the nail out of the slot.
It is important to note that using a pry bar to remove nails from cement can be challenging and may risk pulling up chunks of the floor. If the nails were inserted using a power tool with gunpowder, prying them out will be difficult, if not impossible. In such cases, cutting or grinding the nails off using a Dremel rotary tool or a similar grinder may be a more effective approach.
However, if you opt to use a pry bar, it is recommended to use a large one as it will provide better leverage and quicker results. Additionally, consider using a piece of scrap 2x4 for better leverage.
When choosing a pry bar, the Stanley 55-116 8-inch Nail Puller is a popular option among carpenters. It offers excellent control while prying and features multiple nail pullers. Alternatively, the Shark 21-2220 8-Inch Prybar and Nail Puller is another effective and affordable choice.
