Diamond Blades FAQ


Are diamond blades made from real diamonds?

They can be, but today they’re generally made from lab-created diamonds, which are every bit as hard as natural diamonds. Diamond is the hardest natural substance on the planet known to science – perfect for hardcore cutting jobs.

Can diamond disc cutters cut through anything?

They’re among the most hard-wearing and versatile cutting tools, but they can’t cut through absolutely anything. That said, they are designed to cut through hard materials such as concrete, brick, stone, asphalt and tiles, with certain blades being specifically engineered for specific cutting tasks. If you need help finding the right blade for your needs, we’re here to help.

Do diamond blades last forever?

Despite what Shirley Bassey might have us believe, in the context of cutting blades sadly diamonds aren’t forever. They are incredibly robust though, and proper use and maintenance, such as ensuring the blade doesn’t overheat and is compatible with the cutting material, will significantly extend its life.

Should you cut wood using a diamond blade?

NO! Wood is too soft for the abrasive cutting action of a diamond blade, which counterintuitively can actually cause the blade to wear down more quickly. Additionally, cutting wood with a diamond blade can be dangerous due to the risk of extreme heat and the potential for the wood to catch fire. It's recommended to use blades specifically designed for wood cutting, which have teeth to slice through the material.

What is meant by hard materials, isn’t asphalt hard?

Diamond blades are graded from a hard matrix to a soft matrix. This is the metal alloy that holds the diamonds in place. For optimum cutting the matrix has to wear in tandem with the diamond grit to keep the blade sharp. Whilst asphalt may appear hard, it is very abrasive so requires the hardest matrix bonds. Conversely, products like granite that are very hard, require that the matrix bond is soft enough to keep the blade sharp.

How do diamond blades cut?

Diamond saw blades cut by grinding and are considered super abrasives.
