What You'll Learn

Using a rotary tool with a cutoff wheel
To begin, it is important to prioritise your safety. Wear safety glasses or other eye protection to shield your eyes from sparks and debris. Hearing protection is also recommended, as well as keeping a fire extinguisher nearby. Cutoff wheels can be purchased as part of a kit with the rotary tool or sold separately.
When using the rotary tool, ensure that you hold it firmly in place without applying excessive pressure on the disk when cutting. Lay the rotary tool across a flat surface with the cutoff wheel positioned directly over the nail head. Gently dip the tool so that the disk applies light pressure to the nail. If the first pass does not cut through the nail head completely, reposition the rotary tool at a different angle and attempt a second cut.
After cutting off the nail head, there may still be a portion of the nail protruding from the wood. Use a hammer to gently tap the remnants into the wood, shaping any pulled surface fibres back into place.

Using a carbide burr in a grinder
When cutting off nail heads, it is important to consider the most efficient and safe method. While there are various tools and techniques available, one option is to use a carbide burr in a grinder. Here is a step-by-step guide on using this method:
Step 1: Prepare the Work Area and Protect Yourself
Before you begin, ensure you have a clear and well-lit workspace. Put on safety gear, including a face shield and gloves, as the process can generate sharp chips and debris. It is also recommended to wear ear protection due to the noise produced by the grinder.
Step 2: Choose the Right Carbide Burr and Grinder
Select a carbide burr that is compatible with your grinder. Carbide burrs come in various shapes and sizes, so choose one that is suitable for the size and accessibility of the nail heads you need to cut. Ensure your grinder is a die grinder or another compatible type, such as an air tool or pneumatic rotary tool.
Step 3: Position the Grinder and Carbide Burr
Hold the grinder firmly with one hand and position the carbide burr at the base of the nail head. If possible, try to get the nail head raised above the wood by about 1/4" to 1/2" to provide more room for cutting. This can be achieved using a slide hammer-type nail puller.
Step 4: Cut the Nail Head
Start the grinder and gently apply pressure to the nail head with the carbide burr. Maintain a continuous motion during the cutting process to ensure a smooth and precise cut. The hard-wearing carbide material will enable you to cut through the nail head efficiently. Be cautious and focus on the task to avoid any accidental damage to the surrounding material or yourself.
Step 5: Clean Up and Inspect
Once you have successfully cut off the nail head, power off the grinder and set it aside. Clean up the work area, collecting any chips and debris generated during the process. Finally, inspect your work and ensure that the nail head has been removed cleanly and that there is no remaining debris or residue.

Using a drill bit bigger than the nail's diameter
If you are looking to cut off a nail head, one method is to use a drill bit that is bigger than the nail's diameter. This method is especially useful if you are looking to avoid damaging the surface the nail is embedded in.
First, you will want to get the nail head to protrude from the surface. This can be done by using a nail puller, which can be time-consuming, or a tool such as a pry bar or claw hammer to gently lever the nail out. If the nail is in wood, you can also use a metal detector to locate it. If you can get the head above the wood by 1/4 to 1/2", you will have enough room to cut it.
Once you have exposed the nail head, you can use a drill bit that is slightly bigger than the nail's diameter to drill through the nail. You can use a metal drill bit to push the remainder out, or, if it won't move, drill the nail out. If you are drilling into wood, you can use a small drill bit (1/8" or 3mm) to drill a series of tightly spaced holes around the edge of the nail head. Go around in circles, using the drill bit as a milling tool to get as much wood fibre out from around the nail as possible. Be careful not to let the drill bit snag on the nail.
If you are drilling into a surface other than wood, you can try drilling a hole the diameter of the nail head in a piece of steel, about a quarter-inch thick, and gluing something thin like rubber, leather, or card to one side. Hold it over the nail head and drill through with a drill of the same diameter. When you get to the nail shank, the head should drop off.
This method can be used to remove nails from hardwood flooring or delicate jobs where you want to avoid damage.

Using a hammer and crowbar
Using a hammer and a crowbar to cut off a nail head requires some force and precision. Here is a step-by-step guide on how to do it:
First, assess the situation. Is the nail embedded in wood or another material? If it is in wood, you may need to create some space around the nail head to allow for better leverage and grip. Using a chisel, carefully create a notch in the wood around the nail head. Be cautious not to damage the surrounding material.
Now, take your crowbar and position it under the nail head. Choose a crowbar with a head slightly bigger than your thumb, which will provide a good grip. Place the crowbar securely under the nail head, ensuring it is centred and firmly in place.
With the crowbar in position, take your hammer and give the end of the crowbar a firm strike. This impact should drive the crowbar further under the nail head, creating a divot in the wood and providing a solid grip on the nail.
At this point, you can slowly begin to pry the nail out. Apply force to the crowbar by leveraging your hammer or another tool. Pull up and back on the nail with steady pressure. If the nail does not come out easily, try pulling the crowbar sideways to create a bend in the nail. This will increase the grip and make it less likely to slip from the crowbar.
If you are dealing with a large number of nails or a particularly stubborn one, there are some alternative methods you can try. One approach is to use heavy-duty tools like bolt cutters or a slide hammer with a nail puller attachment. These tools can provide more force and make the process faster.
Remember to wear the appropriate safety gear, including gloves and eye protection, when using tools and working with nails.

Using a saw with a metal blade
If you need to cut the head off a nail, using a saw with a metal blade is a good option. This method is especially useful if you want to cut through a nail that is connecting two pieces of wood, plastic, or metal. It is also helpful if you are dealing with a thicker nail, as sawing can be faster than snipping.
Before you begin, ensure that you are wearing appropriate safety gear, including eye protection and gloves. It is also important to choose the right saw and blade for the job. Reciprocating saws, also known as Sawzalls, are commonly used for cutting nails. You can also use a jigsaw or circular saw, but keep in mind that jigsaws need to rest on a solid surface, which can limit their versatility. If you don't have access to a power saw, a manual hacksaw or keyhole saw can also be used.
Once you have selected your saw, it is crucial to install a metal-cutting blade. Metal-cutting blades are available for most types of saws and typically have a tooth count of more than 10 teeth per inch. When using a reciprocating saw, make sure the saw guard is held tightly against the wood to limit binding and pinching.
When cutting the nail head, work slowly and carefully to ensure a precise cut. If the nail is embedded in wood, you may need to chisel around the head to create some space. Always prioritize your safety and follow the instructions provided by the manufacturer of your chosen saw.
By following these steps and choosing the appropriate tools, you can effectively use a saw with a metal blade to cut off a nail head.
