If you need to cut metal but don’t want to use power tools, you can use scissors instead. They are sturdy and can cut thin metal sheets, shims, and aluminum foils. The best kind of scissors to use for cutting metal is one that is large and sturdy. Generally, scissors can cut up to 1/64-inch-thick metal sheets.
Alternative ways to cut metal
If you’re a skilled DIYer, you might find yourself needing to cut metal for some project. Perhaps you’re replacing HVAC ducts or want to restore the metal flashing on your roof. Other times, you need to cut metal for an upcoming metal craft project. Whichever way you choose to do it, there are a few alternatives you can try.
First, you can use a hacksaw, which is an excellent tool for cutting most metals. However, it isn’t the fastest tool and may take a while to cut through thick metal. If you’re looking for a more precise way to cut metal, consider using a circular saw. Ensure that you use the right blade to ensure a clean cut.
Using a welder
When using a welder to cut metal, remember to use a high-quality rod and follow the directions carefully. Cheap welding rods, such as 6010 and 6011, will gouge the metal when the arc is lit and push the molten metal out. Using a high-quality rod will result in a stronger weld that will last for a long time.
Although a welder isn’t designed to cut metal, it can be used to create precise cuts. Before beginning, mark the path of the cut with an engineer’s chalk. Also, clamp small pieces to prevent them from moving during the cut. Finally, make sure that you have a grounding lead clamped onto the metal to be cut. The current from the grounding lead will be what produces the arc.
Using a hammer and chisel
Before starting cutting metal, it is important to take proper safety precautions. Use safety goggles to protect your eyes from flying metal bits and wear heavy-duty gloves. Also, make sure the hammer and chisel are sharp enough to prevent injury. Hold the chisel at a specific angle on the metal surface. For instance, if you’re cutting a straight line, a 90-degree angle will work best. In contrast, if you’re cutting a groove in concrete, a 65-degree angle is perfect. For small cuts, a 45-degree angle is best.
A cold chisel should be slightly wider than the metal being cut. It should be lubricated with machine oil to help it slip through the grains of the metal. To strike the chisel, hold it by its edge with your thumb and index finger. Next, strike the chisel with a ball-peen hammer, while avoiding claw-peen hammers. You should aim to complete a cut in thirty seconds or less.
Using a bench shear
Bench shears are great tools for cutting metal, whether sheet metal or steel. However, you should use caution when using them to avoid cutting your fingers. It is also recommended that you use a light next to the shear handles to make sure that the cutting process is as accurate as possible.
Bench shears are designed for cutting up to 6″ of metal. The blades of bench shears are sharp, making them perfect for precision work. They have a level arm with a compensating spring that allows for even and fast cutting across the length of the material. Additionally, their rigid body is fixed to the workbench and features adjustable hold down clamp settings. The blades are made of precision-hardened steel and can be used to cut various types of metal, including flat steel, round stock, and rebar.
Bench shears can be operated manually or hydraulically. Most bench shears are small hand-held models, but you can also find electric versions. Electric bench shears are best suited for larger, thick-walled stocks. Regardless of the type of bench shear, you should consider what type of metal you’ll be cutting. You can choose between a rough or smooth edge, depending on your needs.
Using a hacksaw
Hacksaws are relatively easy to use, but they do require proper handling and safety precautions. First, make sure that your workpiece is securely held in a vice. This will prevent any wiggle and excessive vibrations. Also, make sure the blade is properly tensioned. Secondly, it is recommended to hold your hacksaw with both hands so that you have a better balance when cutting. Lastly, remember to use the entire length of the blade, using long, even strokes.
When using a hacksaw to cut metal, it is best to select the right blade. The TPI (teeth per inch) of the blade depends on the type of material you are cutting. High-TPI blades offer smoother cuts while lower-TPI blades provide coarser cuts. The best hacksaw blades are those with 18 to 24 TPI.
