It’s a sign that it will cut the sheet metal and won’t break during the cutting process. Since sheet metal is robust, you must use a solid and high-end diamond blade that will cut it.

Cast iron:

A diamond blade can cut the cast iron. But it has to be a reciprocating saw blade; otherwise, you cannot cut the cast iron pipe or materials using a regular blade. It’s hard and strong and requires a sharp edge to cut it.


The diamond blade can cut the aluminum without any issues. You need to use the same diamond blade that can cut the metal. Only it will cut the aluminum; otherwise, the regular blade will fail to cut it smoothly.

Stainless steel:

The diamond blade can cut stainless steel; there will be no issues. It’s a regular metal where you can use the diamond blade without any issue. But the thing is, your blade life will be reduced if you regularly cut the stainless steel with the diamond blade.

Hardened steel:

Since diamond blades can bear almost any pressure and heat, you can use them to cut the hardened steel; it means the diamond blade will cut the hardened steel without being damaged.

What type and size diamond blade to use to cut metal?

The ferrous type, and regular size diamond blade is perfect to cut metal. Mainly, each diamond blade is not suited to cut everything. Most of the time, each blade is designed to cut a specific type of material or a particular hardness of the material.

It’s tricky to answer what will be the appropriate type and size of the diamond blades for you to cut metal. At first, you need to find out the type of metal you are willing to cut. This should lead you to choose an appropriate bond because they hold the diamond and keep it tightened with the blade.

They also keep them in place. If you intend to cut a rock-solid material, using a diamond blade with a weak bond will be more beneficial. Again, if the purpose is to cut a soft material, you should go for a harder bond diamond blade.

Very few tools are as powerful as a diamond blade for cutting materials. It will provide more safety, greater efficiency with its speed, and extended-lasting capability.

Can I put a diamond blade on a circular saw?

Yes, you can. You can have a lot of small tasks done if you put the diamond blade on a regular circular saw. Keep in mind that you cannot use a particular circular saw for every material. Depending on whether you are using it for hard, medium, or soft materials, the choice of the blade or circular saw may vary.

Sometimes a single circular saw may require more than one blade type according to its usage. A diamond blade in a circular saw is the most popular type of diamond blade.

How long the diamond blades will last depends on the quality of the blade, the type of metal you are cutting, and the cutting technique. Low-quality diamond blades last for a couple of hours of cutting. On the other hand, slightly higher quality diamond blades can offer you cutting time up to a week.

So, how long your diamond blades will last depends on their quality.  Some additional factors may affect the duration of your diamond blades.

If you use the wrong blades for the faulty materials, it’s most likely that your diamond blades will not go to last long. Dry-cutting diamond blades might offer you a longer cutting time than wet-cutting diamond blades.
