Cutting nails in wood is a common problem encountered during renovation projects or when dismantling wooden structures. While there are many tools available for cutting nails, most of them are not suitable for this purpose as they can easily break when coming into contact with nails. This is where a multi-tool comes in handy. A multi-tool, such as the Bi-Metal SMART blade, is designed to cut through wood, nails, and non-ferrous metals without damaging the blade. When using a multi-tool, it is important to attach the blade correctly and position it flat against the timber to effectively cut through the nails. Other tools that can be used include a nail puller with a long handle, a Dremel tool with a cut-off wheel or disc, pliers, and a 4 grinder with a metal cutting wheel.

What You'll Learn

Using a Dremel tool with a cut-off wheel
To begin, ensure you have the correct Dremel accessory for the task. For cutting nails in wood, a cut-off wheel accessory is ideal. It is important to select a wheel that is suitable for the material you are cutting. In this case, a wheel designed for cutting metal nails is required. Carbide-tipped blades are recommended for cutting through nails, as they are durable and long-lasting.
When using the Dremel tool, it is crucial to maintain a balanced and steady grip. Hold the tool with both hands to ensure control and precision. Apply enough pressure to allow the tool to cut effectively, but not so much that you risk damaging the wood or the tool itself. Let the tool do the work for you, and be cautious to avoid applying too much force, which can cause an uneven cut or damage to the surface.
For your safety, it is recommended to wear ear protection when operating the Dremel tool, as these tools can produce a loud noise. Additionally, be mindful of any sparks that may be generated during the cutting process, as grinding wheels have the potential to throw sparks and explode, even when using smaller wheels.
Finally, once you have cut the nails using the Dremel tool and cut-off wheel, you may need to neaten the surface. Swap the cut-off wheel for a sanding accessory, such as a sanding band, to smooth the edges and remove any overhang, leaving a clean and finished result.

Using a nail puller with a long handle
Before you begin, ensure you have the right safety gear, including eye protection and gloves. This will help protect you from any flying nail debris.
Locate the nail head protruding from the wood. Position the nail puller's claws firmly around the nail head, ensuring a secure grip. Apply force by pulling back on the long handle, leveraging the tool's length to your advantage. This will help you generate the necessary force to extract the nail smoothly.
If the nail is particularly stubborn, you can pivot the nail puller slightly to the side to gain more leverage. However, be cautious not to pivot more than 20 degrees to avoid damaging the wood surrounding the nail.
Once the nail starts to come loose, continue pulling steadily until it is completely removed from the wood. If needed, use a pair of pliers to grip and remove the nail if it breaks during the extraction process.
After removing the nail, inspect the wood for any remaining nail fragments. Use needle-nose pliers to extract any small pieces that might be left behind. Fill the nail hole with an appropriate filler, such as an oil-based product like linseed glaze, to ensure a smooth finish and prevent rusting.
By following these steps, you can effectively use a nail puller with a long handle to cut nails in wood, minimizing damage to the surrounding area. Remember to take your time, work carefully, and prioritize safety throughout the process.

Using a Bi-Metal SMART blade
SMART Tool Group has developed a 32mm Bi-Metal blade that can cut through nails quickly and easily without ruining the blade. This blade is designed for cutting wood, nails, and non-ferrous metals. It offers universal cutting up to 51mm deep and is recognised as a safe option for cutting timber with hidden nails.
The Bi-Metal SMART blade is small enough to fit through awkward spaces, making it an effective tool for tradespeople who want to get the job done quickly. To use the Bi-Metal SMART blade, attach the blade to your multi-tool and position it against the bottom of the nail, with the blade sitting flat against the timber. Begin cutting through the bottom of the nail by continuously moving the blade side to side in a hack saw motion until the nail is fully removed. This motion will help increase the life of your blade by spreading the load across the teeth. Without it, your blade will rapidly wear down as only a few of the teeth will be doing the work.
It is important to prioritise safety when using the Bi-Metal SMART blade. Always wear eye protection and other protective equipment, such as a dust mask, non-skid safety shoes, protective apparel, and hearing protection, depending on the conditions. Check the work area for hidden gas pipes, electrical wires, and water pipes before making cuts to reduce the risk of explosion, electric shock, and property damage. Additionally, always check that the blade is free from damage and excessive wear before each use, as using a dull or damaged blade can cause excessive friction, blade binding, and kickback, which may result in injury.
The Bi-Metal SMART blade is a useful tool for cutting nails in wood, especially in renovation projects where you may encounter nail-infested timbers. Its durability and ability to cut through nails without damaging the blade make it a convenient option for tradespeople and DIY enthusiasts alike.

Using a carbide-toothed TS blade
Carbide-toothed table saw (TS) blades are a great option for cutting nails in wood. They are designed to cut through staples, brads, and even the occasional nail without damaging the blade or the user. This is because carbide is harder than mild steel and wrought iron, which are relatively soft metals.
While carbide-toothed TS blades are durable, it is not 100% safe to cut nails with them, as there is a risk of damaging the saw or injuring the operator. Additionally, the flesh-sensing technology on the SawStop can be triggered by cutting through metal, resulting in the need for a new brake and blade.
To use a carbide-toothed TS blade safely, it is important to exercise caution and be mindful of the potential risks. Always wear appropriate safety gear, such as eye and ear protection, and ensure that the blade is properly secured and aligned before use.
When cutting nails with a carbide-toothed TS blade, it is important to maintain a steady hand and control the speed and direction of the cut. Start by positioning the blade flat against the timber, at the bottom of the nail. Then, continuously move the blade side to side in a hack saw motion to cut through the nail. This motion will help extend the life of your blade by spreading the load across the teeth and preventing rapid wear.

Using a jigsaw
Jigsaws are a great option for cutting nails in wood. They are slower and safer than reciprocating saws, which may be too uncontrollable for this task. Jigsaws are also a more useful tool for the average woodworker to have in their arsenal.
To use a jigsaw to cut nails in wood, you will need to attach a metal-cutting blade to the tool. Metal-cutting blades can be purchased for virtually any type of saw, including jigsaws. When selecting a blade, opt for one with a tooth count of at least 10 teeth per inch. SMART has developed a 32mm Bi-Metal blade that is designed for cutting wood, nails, and non-ferrous metals without ruining the blade. This could be a good option for your jigsaw.
Once you have attached the blade, position the jigsaw against the bottom of the nail, with the blade sitting flat against the timber. It is important that the jigsaw is resting on a surface with the blade hanging over the edge. Then, begin cutting through the nail by continuously moving the blade side to side in a hack saw motion until the nail is fully removed. This motion will help to increase the life of your blade by spreading the load across the teeth.
It is worth noting that carbide-toothed blades are capable of cutting through staples, brads, and even the occasional nail without harm. However, this is not a completely safe option for the operator or the saw, and you may still end up damaging your blade.
