Diamond blades are designed to cut hard, abrasive construction materials such as concrete, engineering brick and dense block.
Choosing the right blade improves cutting speed, reduces glazing and protects your saw.
Choosing the wrong one slows the job down, increases wear, increases costs.
This guide explains how diamond cutting discs work, the different types available, and how to select the right blade for concrete and masonry cutting.
Our full range of concrete cutting blades is selected for professional use across dense construction materials. Each blade is specified to balance bond hardness, cooling performance and durability under site conditions.
Diamond cutting discs are steel-core cutting blades with industrial diamonds bonded into segmented cutting edges.
As the blade rotates, the diamonds grind through the materials. As the segment wears, new diamonds are exposed. The hardness of the bond controls how quickly this happens.
Three factors determine performance:
Correct balance ensures consistent cutting speed and longer blade life.
These are the most common professional diamond blades for construction work.
When selecting diamond blades, consider:
Material density
Dense concrete and Class B engineering brick require a blade that is designed to cope with high resistance. Not all brick cuts the same. Engineering brick, especially Class B, is far denser than standard brickwork and can quickly glaze a general-purpose blade. If you’re working with dense materials, see our guide to choosing the right for dense brick to understand bond matching, cooling, and why some blades lose cutting speed.
Engineering brick is significantly denser than standard facing brick and can quickly reduce cutting speed if the bond is mismatched. If you regularly work with Class B units, see our guide on cutting engineering brick properly to understand how density affects blade performance.
Reinforced Concrete
Cutting steel reinforcement increases heat and friction on the blade. Not all diamond blades are designed to withstand this.
Bond Hardness
Incorrect bond often results in the blade glazing.
If a blade begins polishing rather than cutting, the issue is usually glazing rather than wear. Before replacing a disc unnecessarily, read why diamond blades glaze (and how to fix it) to understand how bond and material density interact.
Machine Compatibility
Always check that the RPM of the blade matches your angle grinder, petrol saw or floor saw RPM rating.
Concrete cutting is one of the most demanding applications for diamond blades.
If you regularly cut:
You need a blade specifically designed for concrete cutting performance. Here are all of our concrete cutting blades
Not all concrete cuts the same. Our in-depth concrete cutting guide breaks down what matters on site so you can choose the right disc first time.
Cheap blades often:
Professional diamond cutting discs maintain performance, reduce downtime and last longer under load.
For regular cutting of reinforced concrete, engineering brick or other high-density materials, a blade designed specifically for demanding site work makes a measurable difference. The Pathfinder concrete cutting disc is built to maintain cutting speed and resist glazing in dense construction applications.
