Deelat Industrial offers a wide assortment of circular saw blades for cutting metals and wood. They have a smooth surface and sharp edges for precise cutting, and also have corrosion proof coating to prevent rust and long-term damage. High powered, electric hand saws are also offered for cutting into harder materials such as marble. They offer stability and balance to provide you with optimal control.

Buying a Circular Saw Blade for Aluminum or Plastic Cutting: Types and Things to Consider

Circular saw blades are used on a range of tools, including miter saws, radial saws, cut-off saws, table saws, as well as standard circular saws. Yet not all blades are created equal. Some are designed for quickly chopping wood, while others are built to deliver finer cuts on metal or plastic.

It’s important to choose the proper blade, and that means first choosing a blade that fits the saw you will be using. And secondly, choosing a blade that’s suited for the application you will be using it for. Using a blade with fewer teeth, for example, can damage materials like laminate or acrylic. And smaller blades require saws with faster RPMs; if you use a small blade on a large saw, the blade will not receive enough power.

So what do you need to consider? There are a number of factors to think about, but start by finding out what size the blade needs to be. Consult the owner’s manual of your saw to determine the size. This will provide you with three measurements:

  • Blade Diameter
  • Arbor Size
  • Kerf

Blade diameter and arbor size are determined by the saw. Standard circular saws, for instance, most commonly accommodate a 7-1/4-inch diameter blade, while table and miter saws frequently require 10- or 12-inch diameter blades. Each saw is different, and the wrong sized blade can cause a number of problems.

Additionally, kerf is the thickness of the blade. Typically circular saws can accommodate a variety of thicknesses, and you may want to select a blade with a different kerf for several reasons. Thinner kerf blades are sharper, move faster and remove less material with each cut. This is useful when thin, delicate material is being cut. Thicker kerf blades, on the other hand, remove more material; they’re better for thick wood.

Choosing a Circular Saw Blade for Your Application

Once you know the proper size, you can begin to determine the type of blade that you will need. Here’s another measure you will need to know: The number of teeth on the blade. Most commonly blades range from 24 to 80 teeth, and it’s just as important to choose a blade with the proper number of teeth.

Here’s why: A blade with more teeth makes cleaner cuts, while blades with fewer teeth make faster cuts with rough edges. Blades that have fewer teeth are commonly used to cut wood. But these blades don’t work particularly well with aluminum. For example, a laminate that’s finished with aluminum oxide will likely chip if a blade with less teeth is used, and the blade will become dull faster because the material is harder.

Aluminum circular saw blades and plastic blades typically have more teeth. In general, aluminum and plastic blades have between 40-80 teeth, depending on the type of metal or plastic. Plastics that are prone to heat damage, though, may require a low friction blade with fewer teeth to reduce the heat that’s created during the cut.
