Circular Saw Blades That Can Cut Concrete

Abrasive Corundum Masonry Blade

You can cut concrete, asphalt, and stucco with corundum or hard aluminum oxide blades. The caveat to using this type of blade is that they are less efficient than other blades. You must repeatedly slice the surface for shallow cuts of 1/4 to 1/2 inches deep.

The blades also tend to wear out faster than other types. Most of the time, they produce fine dust, and get so hot that they sparkle. Abrasive corundum masonry blades comes highly recommended you need to make a few shallow cuts.

Diamond Blade

Like what the name says, diamond blades consist of a metal blade with a diamond or metal composite stuck at the end. A new diamond edge will be revealed as the metal mixture wears away over time.

You can be confident that a diamond blade for a circular saw will surpass the efficiency of abrasive-type blade, making it ideal for those who frequently cut concrete.
