Cutting concrete isn’t just about blade size or price — it’s about matching the blade to the material, the tool and the type of work you’re carrying out.
Get it wrong and you’ll deal with slow cutting, glazing, overheating and wasted blades. Get it right and the job runs cleanly, efficiently and without unnecessary downtime.
This guide explains how to approach concrete cutting properly, helping you choose the right blade and avoid common problems on site.

One of the biggest factors in cutting performance is material density.
Different materials place very different demands on a blade:
Dense materials generate more heat and friction. If the blade bond isn’t matched correctly, performance drops quickly and glazing can occur.
For a full overview of blade types and how they perform across different materials, see our diamond blades guide.
Selecting the correct blade improves:
Using the wrong blade often leads to:
A good concrete blade should:
Before choosing a blade, identify what you’re cutting:
Typical slabs, paths and foundations without heavy reinforcement.
Contains steel rebar and requires a blade that can handle both aggregate and steel impact.
High-density materials that can quickly glaze general-purpose blades if the bond is too hard.

Less suitable for heavy reinforced concrete.
The tool you use affects both depth and performance.
Angle grinders are ideal for:
Petrol saws are better for:
Cutting depth depends on:
Understanding this relationship is essential for safe and effective cutting.
Most site work is done dry, but both methods have their place.
Dry cutting:
Wet cutting:
Blade stops cutting effectively due to heat and incorrect bond.
Blade is too hard for the material.
Blade is too soft or unsuitable.
Caused by friction and incorrect blade selection.
If this happens, the blade specification is likely incorrect for the material.
If you’re cutting softer, more abrasive materials like asphalt, using the wrong blade is a common issue. For the correct setup, see our guide on cutting asphalt.
For regular site work, a professional-grade blade is essential.
You need a blade that delivers:
For general concrete, reinforced slabs, dense block and engineering brick:
We recommend a professional segmented diamond blade designed for site use
A diamond blade designed specifically for concrete provides the best performance and durability.
No. Some blades are material-specific. A professional segmented blade covers most concrete and masonry applications.
Yes, but depth and performance are limited compared to petrol saws.
Usually due to incorrect bond hardness for the material being cut.
Don’t force the cut — let the blade do the work. Use the correct blade for the material.
