Metal-Cutting Circular Saw Blades

A circular saw with a metal-cutting blade can quickly complete a variety of tasks, from light-duty chores like trimming pipework or aluminum siding to heavy-duty cutting of angle iron or steel structure.

There are a variety of equipment for accomplishing these chores, ranging from portable multi-tools to tabletop chop saws, so the selection of metal-cutting circular saw blades is vast, and that's before you consider blade materials, metal types they're meant to cut, or the number and shape of the teeth.

Choosing the proper blade for the task isn't easy, and getting it wrong may lead to poor performance at best and the potential for your work to be damaged at worst. It's our goal at Blades Direct to assist you avoid such difficulties by providing you with well-researched purchase recommendations.

Materials

The type of metal you can cut is influenced by the capabilities of your saw, but the construction of the metal-cutting saw blade is more essential.

HSS: High-speed steel (HSS), often known as tool steel, is used to make the most cost-effective blades. This is commonly found in low-cost drill bits, and it works well for woodcutting blades, but metals are significantly harder. It's suitable for cutting softer metals such as aluminum or copper in thin sheets or pipes, but it's not tough enough to cut steel or cast iron. If you're working with thin, nonferrous metals and need to save money, an HSS metal-cutting circular saw blade will usually suffice.

Carbide: Teeth that are harder and keep sharper for longer are required for tougher materials. The saw blade's main body is still made of HSS, but the tips are made of tungsten carbide or titanium carbide and honed to form. Although tungsten is somewhat tougher than titanium, the difference is insignificant. Although we recommend using a diamond saw blade. You can choose a blade with a tungsten or titanium carbide tip if you need an all-purpose blade.

Diamond: Diamond blades are suitable for many materials: concrete, asphalt, mixed materials (universal), tiles, granite and more. When you use a diamond-tipped circular saw blade, you can be confident that your machine will operate well for a long time and have a long service life. Circular saws like the Samedia ESM Steel Cutting Blade with diamond tips are often the best for cutting through the toughest metals without concern of wear and tear over time.

How to choose the best Diamond Saw Blade

Teeth

The number of teeth on a blade has a significant impact on how well it cuts certain materials and how smooth the result is. Good manufacturers give charts to assist you in making your decision (a maximum revolutions per minute may also be suggested). In general, more teeth indicate a smoother cut, whereas fewer teeth suggest faster cutting.

Too many teeth, on the other hand, might make it harder to get rid of the waste. It can cause the blade to overheat or possibly become stuck in the workpiece. Blades for cutting nonferrous metals quickly may have as few as 30 teeth, although general-purpose versions are more likely to have 60 to 80.
