Welcome to our disc cutter guide! A disc cutter, also known as a concrete saw, cut-off saw, or sometimes a concrete grinder, is a power tool often used in construction and landscaping for cutting hard materials such as bricks, blocks, pavers, concrete, tiles, natural stone and structural metals and pipework.
Choosing the right disc cutter for your project involves considering a variety of factors. In this guide, we’ll walk you through everything you need to know to make an informed choice.
Choosing the right disc cutter for your project involves considering a variety of factors. In this guide, we’ll walk you through everything you need to know to make an informed choice.
1. Understand Your Project Requirements
Before diving into the features, take a moment to assess your project. Ask yourself these questions:
- What is the maximum thickness of material you want to cut?
- Will you be cutting indoors or outdoors?
- Do you need straight cuts, curves, or both?
- Do you need to cut other materials like metal, plastic and wood?
2. Choosing the Right Power Source
The first consideration is whether to choose petrol, plug-in electric, or battery-powered machines. Petrol-powered saws were once the standard choice, but advancements in electric saws have introduced significant benefits:
Corded Electric Disc Cutters:
Deliver instant power with a push start, faster cutting, less noise and vibration, no need to mix fuel, and no engine servicing. Zero emissions make them safer and practical for both indoor and outdoor use.Battery-Powered Disc Cutters (COMING SOON TO EVOLUTION):
Combine the benefits of electric cutters with the added flexibility of being able to be used almost anywhere. Recent developments in brushless motor technology and battery design mean these tools can now deliver the power to handle demanding tasks with ease.
Electric disc cutters can also be more cost-effective compared to their petrol counterparts.
3. Blade Size and Depth of Cut
Evolution disc cutter models come with various blade sizes to suit different materials, budgets and cutting depths:
-
230mm (9") Blade: Found in our R230DCT model, offering a 90mm cut depth, which is 50% more cutting depth than equivalent angle grinders. Ideal for laying patios and cutting paving slabs.
-
255 (10") Blades: Available in models like the R255DCT. Perfect for cutting standard bricks in one pass.
- 300mm (12") Blade: Featured in our R300DCT & R300DCT+ model, providing a 115mm cutting depth. Great for bricks, blocks, paving, reinforced concrete, and decorative stone.
4. Blade Type and Compatibility
Diamond blades are the ultimate choice for cutting through tough materials. They provide impressive cutting force and longevity. Below we explain the differences between our Evolution disc cutter blades.
-
General Purpose Diamond Blade: Great for cutting hard and abrasive masonry such as bricks, pavers, stone, and reinforced concrete.
-
Premium Diamond Blade: Has 33% more diamonds for faster cutting and longer life. Particularly suitable for tough masonry, granite, and pipework.
- Heavy Duty Diamond Demolition Disc: Designed with tough cuts and versatility in mind, providing up to 30x longer life than abrasive discs. Cuts through most building materials including, metal, bricks, tiles, wood, plastics, and more.
Evolution disc cutters feature an industry standard 22.2mm bore. Evolution blades are compatible with many other manufacturers machines such as Dewalt, Makita, Milwaukee. Just remember to check the bore size and the disc size before purchase.

5. Dry or Wet Cutting
Concrete and construction dust can pose health risks. Using disc cutters with water suppression significantly reduces dust levels and adds lubrication for easier cutting and extends blade life.
Evolution’s R300DCT+ is equipped with on-board water suppression. All our water fed saws can be supplied from a pump pressurised bottle or mains pressure water supplies.
Always wear appropriate respiratory protective equipment (RPE) like FFP3 masks or half masks with P3 filters.

6. Additional Features to Consider
- Blade Guards: These are an essential safety feature to mitigate dust production and maximise visibility of the cut surface. All Evolution disc cutters feature large, angle adjustable blade guards for maximum protection.
- Wheeled Skid Plates: Wheels underneath the disc cutter help you make straight cuts and reduce the strain when bending over to make long cuts at ground level. Their placement also allows the tool to be put down safely before the blade has stopped spinning. All Evolution disc cutters feature wheeled skid plates.
- Electronic Brake Control: Stops the blade in seconds, enhancing safety. This important feature comes as standard on every Evolution disc cutter.
