Choosing the Right Circular Saw Blade for Cutting Metal

The finish of your cut can be drastically affected by the blade you use. Therefore, it is important to select the right circular saw blade for cutting metal. Unlike wood cutting blades, metal cutting blades are not interchangeable. This is because a metal-cutting saw has a collection bin to prevent metal chips from getting into the machine, while a wood-cutting saw is designed without one. If you do use a wood saw on metal, only use a 7 1/4-inch blade and preferably a worm drive blade with extra torque. However, it is recommended to use a blade specifically designed for cutting metal.

When choosing a blade for metal cutting, you should consider the type of metal you are cutting. For non-ferrous metals, such as brass, aluminum, copper, or lead, a carbide-tipped abrasive cutoff wheel is the best option. Carbide-tipped blades last up to 10 times longer than regular steel ones. The pitch and design of the blade you choose will also vary depending on the thickness of the metal. A higher tooth count is suitable for thinner metals, while a lower tooth count is better for thicker ones. The packaging of the blade should specify what material and thickness it is appropriate for, and if you have any doubts, you can always contact the manufacturer.

While most home improvement stores only stock circular saw blades for cutting wood, you may need to search online or visit a specialty tool store to find blades for cutting metal. Do not make your selection based solely on price, as you may not be satisfied with the results. Always ensure that the blade you purchase has the correct diameter and arbor size to match your saw.
