Cutting through hardened steel nails can be a challenging task that requires the right tools and safety precautions. While some people suggest using power tools like angle grinders, circular saws, or reciprocating saws, others opt for traditional hand tools such as hacksaws, bolt cutters, or pliers. The choice of tool depends on factors such as the thickness of the nails, accessibility of the work area, and the desired precision of the cut. In all cases, it is crucial to prioritize safety by wearing appropriate protective gear and ensuring a controlled working environment to mitigate the risks associated with metal cutting.

What You'll Learn

Using a hacksaw
Hacksaws are a general-purpose metal-cutting saw that can be used to cut through hardened steel nails. They are defined by their blade length, with blade sizes ranging from 6-inch mini hacksaws to heavy-duty 24-inch tools. When selecting a hacksaw, it is important to consider the size of the project and the amount of physical effort required. Smaller hacksaws are ideal for cutting through nails, screws, and bolts, as they can easily fit into narrow gaps.
To cut through hardened steel nails with a hacksaw, it is recommended to use the right type of blade. Carbide-tooth blades are more expensive but will last longer and provide better cutting performance. Bi-metal blades, such as Sandflex, are also suitable for cutting metal and can improve the cutting ability of the hacksaw. Additionally, it is crucial to wear the appropriate safety gear, such as PPE, to protect against any flying metal chips or sparks.
When using a hacksaw, the direction of the teeth on the blade is important. The force should be applied in the direction in which the teeth point. This ensures effective cutting and minimizes the risk of blade damage. While hacksaws can cut through hardened steel nails, it is important to note that it is not a quick procedure and may require some physical effort.
For a more efficient cutting experience, it is recommended to use power tools such as an angle grinder or a circular saw. These tools can cut through metal faster and with less effort compared to a hacksaw. However, they may not be accessible to everyone, and safety precautions should be followed when using power tools.
In conclusion, using a hacksaw equipped with the appropriate blade, such as a carbide-tooth or bi-metal blade, is a viable option for cutting through hardened steel nails. While it may require more physical effort and time compared to power tools, it is a cost-effective and accessible method for DIYers and metalworkers. Remember to prioritize safety and follow the correct techniques to ensure a successful cutting experience.

Employing a Dremel tool
Dremel tools with cut-off wheels are like mini angle grinders and can be used to cut hardened steel. You can buy a pack of cut-off discs for around $5, or you might already have some if you own a rotary kit. The discs are made of fiberglass, and while they can be cheap, it is worth investing in a good brand as the cheaper ones deteriorate quickly.
If you are looking for a slower but safer option, you can purchase diamond-coated cut-off wheels for your Dremel tool. These wheels will not "explode" like the standard, more brittle cut-off wheels.
To use a Dremel tool, simply make a slight cut in the nail and then use pliers to snap off the rest. This method is safer and quicker than using vice grips or linemans, which can be time-consuming and require a lot of force.

With bolt cutters
Bolt cutters are a versatile tool that can cut through hardened steel nails. They are heavy-duty wire cutters with long handles and a geared cutting mechanism that magnifies the force you apply to the handles. They are designed to cut large-diameter fasteners, such as screws, bolts, padlocks, and rebar.
When using bolt cutters to cut through hardened steel nails, it is important to ensure that the cutting blades fit completely around the shank of the nail. If the nail is embedded in wood or another material, you may need to create some space around it by chiselling or using a similar method.
To achieve the maximum cutting force, work the tool around the nail until the shank is as close to the pivot point as possible. This will allow you to apply the necessary force to cut through the hardened steel.
While bolt cutters are effective for cutting hardened steel nails, they may leave a stub, so it is important to consider the desired finish of the product. Additionally, due to their large size, bolt cutters may not be suitable for all tasks, especially in tight spaces.
Overall, bolt cutters are a powerful tool that can be used to cut through hardened steel nails. They provide a simple and effective solution, but users should be mindful of the space required and the potential for stubs left after cutting.

Angle grinders
An angle grinder is a powerful tool that can cut through hardened steel nails. It is equipped with a fast-spinning disc or blade that can cut through various materials, including hardened steel, concrete, and masonry. Angle grinders have a powerful motor that rotates the cutting disc at high speeds, allowing it to slice through hardened steel nails with ease.
There are a few factors to consider when using an angle grinder to cut through hardened steel nails. Firstly, it is important to choose the correct type of cutting disc for the job. Angle grinders can be equipped with different disc sizes and types, such as diamond blades, abrasive wheels, and metal cut-off wheels. It is also important to consider the thickness and hardness of the steel nails, as well as the operator's skill level.
Safety is a crucial aspect when using an angle grinder. It is important to follow safety guidelines, wear appropriate protective gear, such as eye and ear protection, and ensure the grinder is properly secured. Additionally, using a secure clamp or vice to hold the steel nails in place is essential.
When using an angle grinder to cut hardened steel nails, it is recommended to use a diamond blade that is rated for cutting ferrous metal. These blades last longer, cut faster and cleaner, and wear down slower than abrasive discs. It is also important to inspect the blade before each use and ensure that the bolt holding the blade is not overtightened.

Carbide-tooth blades
When choosing a carbide-tooth blade, consider the type of metal you will be cutting and the desired type of cut. For example, Bosch offers carbide-tipped blades for jigsaws, reciprocating saws, and oscillating multitools, providing freedom of movement when working with metal pipes, fittings, and screws. Carbide-tooth blades are also available for circular cutting in sheet metal or nail-embedded wood.
Evolution Power Tools offers a range of carbide-tipped blades designed for maximum performance. Their tungsten-carbide-tipped blades are suitable for cutting mild steel, aluminum, stainless steel, wood, and multi-materials, including wood with embedded nails.
EZARC carbide oscillating saw blades are another option that can handle tough cutting jobs on hardened materials. These blades are designed for use with oscillating multitools and are suitable for professionals and DIY enthusiasts. They can effectively cut through hardened steel nails, screws, bolts, and other hard materials.
When using carbide-tooth blades, it is important to follow safety precautions and ensure that the blade is suitable for the specific type of metal and cutting task. Additionally, proper tool maintenance and blade care can extend the lifespan of carbide-tooth blades and improve their performance.
Overall, carbide-tooth blades provide a durable and efficient solution for cutting hardened steel nails, offering precision, longevity, and the ability to handle demanding cutting tasks.
