As an angle iron supplier, I often encounter customers who are looking for alternative ways to cut angle iron when a saw is not available. Cutting angle iron is a common task in various construction, DIY, and metalworking projects. While a saw is the traditional tool for this job, there are situations where you might not have one at hand. In this blog post, I'll share several effective methods to cut angle iron without a saw, which can be useful in a pinch.
Method 1: Using a Torch
One of the most reliable ways to cut angle iron without a saw is by using a torch. This method is particularly suitable for thick angle iron. There are two main types of torches you can use: oxy - acetylene torches and propane torches.
Oxy - acetylene torches are more powerful and can cut through thicker materials more quickly. They work by combining oxygen and acetylene to create a high - temperature flame. To use an oxy - acetylene torch to cut angle iron:
- Safety First: Wear appropriate safety gear, including welding gloves, a welding helmet, and flame - resistant clothing. Make sure the work area is well - ventilated.
- Set Up the Torch: Connect the oxygen and acetylene tanks to the torch according to the manufacturer's instructions. Adjust the pressure regulators to the appropriate settings.
- Preheat the Angle Iron: Open the acetylene valve slightly and ignite the torch. Adjust the flame to a neutral flame, which has a clear inner cone. Hold the torch about 1/8 inch from the angle iron and preheat the area where you want to make the cut.
- Start Cutting: Once the angle iron is red - hot at the cutting point, open the oxygen valve. The oxygen will react with the hot metal, causing it to burn away and create a cut. Move the torch slowly along the cutting line, keeping the flame at the right distance from the metal.
Propane torches are less powerful than oxy - acetylene torches but are still effective for thinner angle iron. The process is similar to using an oxy - acetylene torch, but you'll need to preheat the metal for a longer time.
Method 2: Angle Grinder
An angle grinder is a versatile power tool that can be used to cut angle iron without a saw. It uses a rotating abrasive disc to grind through the metal. Here's how to use an angle grinder to cut angle iron:
- Choose the Right Disc: Select an abrasive cutting disc that is suitable for cutting metal. Make sure the disc is rated for the thickness and type of angle iron you are cutting.
- Safety Precautions: Wear safety goggles, a dust mask, and ear protection. Secure the angle iron firmly in a vise or clamp to prevent it from moving during the cutting process.
- Start Cutting: Hold the angle grinder firmly with both hands. Turn on the grinder and let the disc reach full speed before touching it to the angle iron. Slowly lower the disc onto the metal and apply gentle pressure. Move the grinder along the cutting line, making sure to keep the disc perpendicular to the angle iron.
- Cool the Disc: As you cut, the disc can get very hot. Periodically lift the grinder off the metal to allow the disc to cool down. This will help prevent the disc from overheating and wearing out quickly.
Method 3: Using a Chisel and Hammer
For thinner angle iron, you can also use a chisel and hammer to make a cut. This is a more manual method and requires more physical effort, but it can be effective in a pinch.
- Mark the Cutting Line: Use a ruler and a marker to mark the line where you want to cut the angle iron.
- Secure the Angle Iron: Clamp the angle iron firmly in a vise or against a solid surface. Make sure it is stable and will not move while you are cutting.
- Start Chiseling: Place the chisel on the marked line and strike it with a hammer. Make sure to hold the chisel at the right angle (about 30 - 45 degrees) to the surface of the angle iron. Make a series of small, controlled strikes along the cutting line. As you progress, the chisel will gradually cut through the metal.
- Finish the Cut: Once the chisel has made a deep groove along the cutting line, you can use a pair of pliers to break off the remaining piece of metal at the end of the cut.
Method 4: Plasma Cutter
If you have access to a plasma cutter, it can be an excellent option for cutting angle iron. Plasma cutters use a high - velocity jet of ionized gas (plasma) to melt and blow away the metal. Here's how to use a plasma cutter to cut angle iron:
- Set Up the Plasma Cutter: Connect the plasma cutter to a power source and a compressed air supply. Adjust the settings according to the thickness of the angle iron.
- Safety Measures: Wear safety glasses, a welding helmet with a proper shade, and protective clothing. Make sure the work area is clear of flammable materials.
- Start Cutting: Hold the plasma cutter torch about 1/8 inch from the angle iron. Press the trigger to start the plasma arc. Move the torch slowly along the cutting line, keeping a steady hand. The plasma will quickly melt through the metal, creating a clean and precise cut.
