Why should not saw iron with a jigsaw?

When cutting iron, the friction generated makes the machine overloaded, easily hot and damaged. In addition, the possibility of the cutting line being washed out and the surface being uneven is also high, affecting the quality of the product. 

That is why in production and construction, people clearly divide between wood sawswood saws and iron saws. The right machine, the right data not only helps the work faster but also ensures safety for the user.

Can a jigsaw cut iron?

Jigsaws can still cut some thin metals such as iron, corrugated iron or aluminum. However, the quality of the cut will not be as good and the efficiency will not be as high as when using the right iron saw such as a saber saw. 

In case you do not have an iron saw available, you can still use a jigsaw instead. The important thing is to choose the right type of saw blade. 

Jigsaw blades for metal are usually made from high-grade steel alloy, have high durability, good impact resistance and stable operation in harsh working conditions. The saw teeth are designed to be sharp and hard, helping to cut faster and neater, while limiting the impact on the surrounding area.

Here's how to choose a jigsaw blade for cutting iron:

- Prefer blades with large, progressive tooth pitches from 4 to 5.2 mm for high efficiency.

- Use for metal sheets from 1.5 mm to 10 mm thick and hollow metal pipes with a diameter of about 2 to 3 cm.

- Choose a single-shank (T-shank) type to fit most popular jigsaw models such as Bosch, Makita and many other brands.

Should I use a jigsaw to cut iron?

Handheld jigsaws can still cut iron and support daily work. However, due to their compact structure, average capacity and limited cutting speed, the efficiency when cutting iron will not be as high as that of specialized machines. 

Experts often advise against using jigsaws to cut thick iron because the job will be difficult to complete. If you want to take advantage of it, you should only cut on thin, soft and not too thick iron bars. When using the right specialized saw blade, the cut will be faster and cleaner. 

In fact, jigsaws can cut hollow iron pipes with a thickness of about 2 cm. With curves or bends, the machine is only suitable for thin iron sheets from 2 to 3 mm.

For solid iron, thick iron or large pipes, you should use a saw or a specialized iron cutter for the best results. Although not as professional as handheld iron cutters, a jigsaw is still a convenient choice if you only need to handle thin iron and do not want to carry bulky equipment.
