 Can a Jigsaw Cut metal?

Cutting metal with a jigsaw is not as tricky as it seems in some DIY guides. You can do it yourself easily; you have to follow the proper technique to get the best and finest metal cut. 

Jigsaw is the type of tool which most of us aren’t using the whole year. So, when we have to cut a metal piece urgently, we are confused about how to cut it the best way.

Here we are about to discuss how do you cut metal with a jigsaw:

Safety First, Safety Must

Whether you are cutting metal at home, in a workshop, or in an industry, such tasks always have a safety risk. Deafening noise and small particles coming out from the cut can cause severe damage to your ears, eyes, or other body parts.

You should make all the safety measures to ensure zero injuries during the task. Wear a dust mask, earplugs, protective helmet, and eyewear as a protection kit.

Step by Step Guide For Cutting Metal With a Jigsaw

Cut Sheet Metal With Jigsaw

Sheet metal can consist of various materials like aluminum, steel, or wrought iron but the cutting method is almost the same for any metal sheet. You have to follow these steps:

  • Choose A Proper Area For Cutting

You just can’t put a metal sheet anywhere for cutting. Metal sheets vibrate at a high pace when a fast-moving jigsaw blade cuts them, so you have to place it at an even, flat, and unmoving material to make cutting a smooth ride.

  • Take Measurements

Take the measure of the piece you want to cut and draw a straight line to cut the sheet metal. Draw the cut pattern with a marker if you’re going to cut it in a curve or circle. Ensure to re-measure the drawn line or pattern to eliminate any chance of error.

  • Cut The Sheet Metal

Now cut the sheet metal slowly and gently. Don’t put in any effort yourself; gently push in the jigsaw and let it do its job. This way, you can achieve sharp and thinner edges instead of rough ones along with minimum loss of material during the cut.

Cut Corrugated Metal With Jigsaw

How To Cut Metal With A Jigsaw

Cutting corrugated metal with a jigsaw might be slightly different from cutting any metal, but it comes with the same basic challenges. 

If you are cutting a corrugated metal that will be used outdoors or exposed to extreme weather conditions, you need to be extra careful with all the steps. Here’s how you can cut corrugated metal the best way:

  • Find A Supporting Material

Clamps are the best supporting material for corrugated metal because they produce no vibration during cutting and hold it tightly. Sawhorses can also be a good option, but they do not eliminate vibration.

  • Marking

It would be best to have a ruler, measuring tape, and some markers to take measurements of the perfect cut. Corrugated metal always has ridges, so be careful while marking because even a 1-inch difference can make the metal useless.

A straight edge can come in handy to draw and cut the corrugated metal straight.

  • Cut The Corrugated Metal

Now the central part comes to cut the corrugated metal through those ridges. Use the right blade and set it at a low rotation speed. Push it through the marked line slowly and gently.

If you are cutting an extended area, you may need to apply cutting oil to the jigsaw blade because the jigsaw blade might get hot and lose its effectiveness with the friction of the cut. Cutting fat helps it cool down and use it for a long time.

Keep cutting through the marked line and make sure that both sides have support so that it doesn’t fall and cause any injury or inconvenience.

What is the best jigsaw metal cutting blade?

The best metal cutting blades come in different sizes and materials. But, if you want to cut metal like a pro, you should go with Bi-Blade. This blade is a combo of HSS and HCS. This blade material is specially designed for heavy-duty cutting of hard metals like steel, aluminum, iron, etc.

It is made up of abrasive material. Thus it helps to cut metals finely without getting dull with time.

Which Jigsaw Blade Should You Choose?

For Cutting Metal Blade

Choosing a jigsaw blade is not a difficult task if you have a clear picture of your needs in your mind. Every blade is made for a specific operation, so you need to be sure about how you will use it. However, an ideal blade should have 21-24 teeth per inch.

A blade with such specs would be enough to cut through any hard metal. There are different types of blades available, some of which are:

High Carbon Steel (HCS) blade

High carbon steel blades are malleable, which might cause them to divert from their intended path, and they wear faster than other blade materials. However, because they are very affordable, they are sold in a large quantity for standard wood cutting.

High-Speed Steel (HSS) blade

High-speed steel blades are tougher and more sturdy than high-carbon steel blades, but they are less elastic. They’re also more sensitive to thermal damage.

Wood products, metals, and reinforced plastic can be cut using high-speed steel blades.

Tungsten Or Carbide blade

Tungsten carbide blades offer the highest high thermal stability and are the most lasting blade materials. This is because their cutting edge is covered in tungsten alloy powder rather than having teeth.

They are used in heavy-duty operations such as cutting ceramics, metals, or fiberglass.
