What You'll Learn
Use a hacksaw with a Sandflex bi-metal blade
Using a hacksaw equipped with a Sandflex bi-metal blade is an effective way to cut hardened steel nails, although it is not a quick process. The Sandflex blade is a bi-metal blade with precision teeth designed for all kinds of metal sawing. It combines superior cutting performance with wear resistance and flexibility, outperforming conventional hard, high-speed, and flexible blades.
When using a hacksaw with a Sandflex bi-metal blade to cut hardened steel nails, it is important to take your time and work slowly and carefully. Here is a step-by-step guide:
- Ensure you are wearing appropriate personal protective equipment (PPE) for eye, hand, and body protection.
- Adjust the frame of the hacksaw to fit the blade securely and tightly.
- Select the appropriate tooth count (TPI) for the blade. For hardened steel, a blade with a lower TPI, such as 18 or 24, is generally recommended.
- Position the hacksaw at the desired cutting angle and apply firm but controlled pressure.
- Use a steady back-and-forth sawing motion, allowing the blade to do the work. Do not try to force the cut, as this can damage the blade or result in breakage.
- Take your time and regularly pause to allow the blade to cool down and prevent overheating. Dip the blade in a lubricant such as cutting oil to further reduce friction and heat buildup.
- As you get closer to completing the cut, you may need to adjust your technique and angle of attack to avoid binding the blade.
- Once the cut is complete, inspect the blade for any signs of wear or damage. Replace the blade if necessary before starting a new cut.
Remember that cutting hardened steel nails with a hacksaw and Sandflex bi-metal blade is a slow and deliberate process. It is important to prioritize your safety and the integrity of your tools over speed. Always follow the manufacturer's instructions and recommendations for both the hacksaw and the Sandflex bi-metal blade.

Cut-off wheels with a grinder
Cutting hardened steel nails can be challenging due to the hardness of the material. One effective method is to use a grinder with a cut-off wheel, also known as a cutting wheel or abrasive blade. Here are some detailed instructions for using this technique:
Selecting the Right Grinder and Cut-off Wheel
Choose an angle grinder with a higher wattage to ensure it has sufficient power to cut through hardened steel. Grinders with larger motors will generally provide better performance. Additionally, ensure your grinder has a guard to protect you from sparks and debris, and always use the handle for stability and control.
When selecting a cut-off wheel, it's critical to choose one designed for cutting hardened steel. Look for labels or markings that specify compatibility with metal or steel. Avoid using a grinding wheel or a wheel not intended for steel, as it can lead to accidents or damage. Soft wheels are traditionally used for hardened steel, but some sources suggest that hard abrasives like silicon carbide can be more effective. Diamond-coated cut-off wheels are also an option, as they are less prone to shattering.
Safety Precautions
Safety should be a top priority when working with grinders and cut-off wheels. Always wear appropriate safety gear, including safety goggles, hearing protection, a dust mask or respirator, gloves, and long-sleeved clothing to protect your arms from sparks. Ensure the work area is well-ventilated to reduce the risk of inhaling harmful fumes.
Cutting Process
Before starting, make sure the cut-off wheel is correctly installed and tightened. Secure the hardened steel nail you'll be cutting by clamping it or holding it firmly in place. Mark the cutting line on the nail, and ensure the grinder follows this line during the cutting process. Maintain control of the grinder with both hands and pay close attention to the progress of the cut.
Post-Cutting Steps
Once you've completed the cut, turn off the grinder and allow the wheel to come to a complete stop before setting it down. Give the cut nail time to cool down, especially if you used a coolant during the cutting process. Hot steel can be dangerous, so exercise caution when handling it. Examine the cut surface for any imperfections, and use a deburring tool or sandpaper to smooth out any rough edges if needed. Finally, clean up the work area by removing any debris, metal shavings, or leftover coolant.

Diamond-coated cut-off wheels for a dremel
Dremel's diamond-coated cut-off wheels are designed to last and not lose their shape or break. They can be used for cutting, sawing, and carving hard materials such as marble, concrete, brick, porcelain, ceramics, and hard epoxy, as well as soft and hardwood. The wheels are also effective for cutting bolts and other metallic items.
When using a diamond-coated cut-off wheel with a Dremel tool, it is important to use a two-handed golf grip and the right angle attachment when making cuts that are hard to reach. To prolong the life of the wheel, it is recommended to avoid applying excessive pressure and to stay within the RPM limits.
Diamond-coated cut-off wheels for Dremel tools are available in different sizes, including the 545 Diamond Coated Wheel with a 1-1/2 inch (38.1 mm) diameter and the Dremel 545 1-inch (22.2 mm) Diamond Coated Wheel. These wheels can be used with the Dremel EZ SpeedClic mechanism, which allows for fast and easy wheel changes without the need for tools.
While diamond-coated cut-off wheels for Dremel tools can be effective for cutting hardened steel nails, it is important to prioritize safety and follow proper procedures and precautions when working with power tools and hardened materials.

Angle grinder
An angle grinder is a powerful tool that can be used to cut hardened steel nails. Here are some instructions to help you get started:
First, it is important to prioritise safety when working with an angle grinder. Ensure that you are working in a well-ventilated area as cutting hardened steel generates sparks and dust. Inspect your equipment before starting; check the grinder, wheel and accessories for any damage and replace any faulty parts.
Next, select the appropriate cutting wheel for your angle grinder. There are two main types of wheels: grinding wheels and cutting wheels. For cutting hardened steel nails, you will need a cutting wheel designed specifically for cutting metal. Cutting wheels come in various sizes, typically ranging from 4 to 9 inches in diameter. Choose a size that suits your project and the space you are working in. Thicker cutting wheels can withstand more lateral pressure, making them suitable for heavy-duty cutting, but they may create more friction and sparks. Ensure the wheel is correctly installed and tightened before use.
When you are ready to cut, use both hands to maintain control and minimise the risk of accidents. Mark the precise cutting line on the hardened steel nail with a marker or chalk. Work slowly and deliberately, following the manufacturer's guidelines for your specific angle grinder model.
With the right precautions and techniques, an angle grinder can be an effective way to cut hardened steel nails.

Hammer and chisel
Using a hammer and chisel to cut hardened steel nails is a traditional method that requires force and precision. Here are some detailed steps and considerations for this technique:
Firstly, it is important to choose the right chisel. The chisel should be made of hardened steel or an equally strong material to withstand the impact. Check that the chisel is not cheap or annealed, as these will not effectively cut through hardened steel nails. A carbide-tipped chisel, for example, can be an effective choice.
Next, ensure you have a sturdy hammer that can deliver a strong, controlled blow. A ball pein hammer, for example, can be used to strike the chisel with force. When using the hammer, aim for a steady and controlled strike on the chisel to direct the force onto the nail.
The technique requires a firm grip on the chisel and a precise strike with the hammer. Hold the chisel at an appropriate angle to the nail, and strike the chisel with the hammer. The force of the blow, combined with the hardness of the chisel, should cut through the nail. It may take several attempts, and the process may need to be repeated for each nail.
This method can be physically demanding and may not always result in a clean cut. It is important to prioritize safety when using this technique, as the force required can lead to injury or damage if not executed properly. Always wear protective gear, including gloves, eye protection, and ear protection, and ensure you are working in a well-ventilated area to avoid inhaling any dust or debris.
Using a hammer and chisel to cut hardened steel nails is a viable option, but it requires the right tools, force, precision, and safety precautions.
