Homeowners may not need to cut metal frequently, but when they do, this is usually an important job. Having the right tools on hand can lead to greater success. Metal cutting circular saw blades can make clean cuts on metals of different thicknesses and types.

A clean incision makes work safer because it reduces the chance that someone will suffer skin cuts due to the jagged edges on the metal. The DeWalt 14-inch blade is our favorite round blade because it uses a large-format design to provide extremely clean cuts.

When buying a metal cutting saw blade, pay close attention to the size and material of the saw blade to match your most frequent cutting work.

The manufacturer measures the diameter of the circular saw blade. For homeowners, blades between 8 and 14 inches are the most common. Choosing the correct blade diameter is important to ensure that it fits your saw correctly.

Almost all metal cutting circular saw blades use high-speed steel (HSS) material for the entire saw blade.

The cheaper blade will have serrations composed of HSS. More expensive blades will add carbide tips to the teeth of the round blades to improve durability.

Once you have determined the appropriate material and size of the round blades you want to buy, you can focus on some of the functions that separate these blades from each other.

The circular saw blade will have a variable number of teeth. (Each upper point on the serrated edge of a circular blade counts as a tooth.) Generally, the number of teeth of a blade is between 30 and 80.

One potential disadvantage of using a large number of teeth is that it is difficult for the blade to pull the cut metal away from the cutting line, which may cause cutting blockages, making it more difficult to perform straight cuts.

The gap between the teeth (also called alveolar) allows the blade to expand when heated while cutting. These gaps actually provide a higher level of overall performance for the blade, even if they seem strange.

The width of the teeth is equal to the thickness of the round blade. The difference between wide and narrow teeth is small, but wide teeth will remove more material than narrow teeth, which may affect cutting accuracy. Cutting jobs that require tight tolerance measurements will require narrower teeth.

Some of the cheapest metal cutting circular saw blades cost $10 to $35, but their diameter is usually less than 10 inches. A blade with a carbide blade and a diameter of 10 to 14 inches will cost 35 to 150 US dollars.

Answer: Not necessarily. Some people prefer to use angle grinders when they need to cut metal quickly or where it is difficult to install a saw in a small space. However, angle grinders can perform rough cuts.

Answer: You can sharpen all metal blades manually with a file, but you need special tools to sharpen round blades with carbide tips.

DeWalt 14-inch blade: Available on Amazon

Our view: This DeWalt blade is a multifunctional device that can perform clean cuts on all types of metals without burrs.

What we like: DeWalt makes this blade in the United States. It can effectively dissipate heat to maximize performance.

What we don’t like: higher cost than some other blades.

Floyd Diablo Steel Demon 10-inch blade: Available on Amazon

Our view: The price is reasonable, but this model has the versatility of cutting many different types of metals.

What we like: Use a mixture of ceramic tips and metal to provide sharp cuts. The pattern of the blade eliminates burrs.

What we don’t like: Sometimes sparks will be generated after a few times of use, which will affect the cutting force.

Irwin 12-inch blade: available on Amazon

Our view: Use cemented carbide tips in its structure to ensure long-lasting performance and make it value for money.

What we like: A variety of high-grade metals will be cut cleanly. The blade includes anti-vibration ventilation holes to reduce the chance of hiccups during cutting.

What we don’t like: Not suitable for thicker metals.
