What Are Cutting and Grinding Discs?
Cutting and grinding discs are abrasive or toothed tools designed for use with angle grinders, circular saws, and reciprocating saws to cut through, grind down, or finish construction and fabrication materials. They cover a wide range of applications including cutting structural steel and pipework, removing welds and surface coatings, cutting stone and masonry, and preparing surfaces for finishing or coating.
Cutting discs are typically thin, allowing fast, precise cuts with minimal material loss. Grinding discs are thicker and are used for material removal, surface preparation, and shaping rather than cutting through material. Diamond discs and blades use industrial diamond abrasive rather than bonded grit, making them suitable for very hard materials like stone, concrete, and ceramic where conventional abrasive discs would wear out quickly. TCT (tungsten carbide tipped) circular saw blades use hardened carbide teeth for cutting timber, sheet materials, and some plastics, delivering clean cuts and long service life compared to standard high-speed steel blades. Reciprocating saw blades are used for demolition cutting, cutting through pipes and fixings, and making access cuts in wall and floor materials.
Cutting and Grinding Discs by Type
Each disc and blade type is designed for a specific material and cutting task for optimum performance and safety.
Choosing the Right Cutting or Grinding Disc
The right disc depends on three things: the material being cut or ground, the machine being used, and the task being performed. Material compatibility is essential for both performance and safety. Using a disc rated for metal on stone will damage the disc and produce poor results. Using a stone disc on metal creates a safety risk. All discs and blades must be rated for the RPM of the machine being used, and the disc or blade diameter must be compatible with the guard fitted to the machine.
For metal cutting, thin MAX cutting discs (1mm to 2mm) give fast, clean cuts with minimal heat generation. For grinding and surface prep on metal, use a dedicated grinding disc rated for the task rather than a cutting disc, which is not designed to withstand lateral pressure. For stone and masonry on a site angle grinder, MAX stone discs or diamond angle grinder blades are the correct choice depending on the hardness of the material.
| Task | Recommended disc or blade | Machine |
|---|---|---|
| Cutting steel, box section, pipe | MAX metal cutting disc (thin) | Angle grinder |
| Weld removal, surface preparation (metal) | MAX metal grinding disc | Angle grinder |
| Cutting stone, masonry, kerbs, paving | MAX stone disc | Angle grinder |
| Cutting tiles, ceramic, porcelain | Diamond angle grinder blade | Angle grinder |
| Cutting timber, sheet materials, boarding | MAX TCT circular saw blade | Circular saw or mitre saw |
| Demolition, pipe, access cuts in walls | Reciprocating saw blade | Reciprocating saw |

Frequently asked questions
What is the difference between a cutting disc and a grinding disc?
Cutting discs are thin, typically 1mm to 2mm, and are designed to cut through material with a narrow kerf and minimal heat generation. They should only be used for cutting, not grinding, as they are not built to withstand lateral or side pressure. Grinding discs are thicker, typically 6mm or more, and are designed for material removal, weld grinding, surface preparation, and shaping. Using a cutting disc for grinding will cause the disc to break up, which creates a serious safety hazard.
What materials can angle grinder discs cut?
Angle grinder discs can cut steel, stainless steel, cast iron, stone, concrete, masonry, tiles, and ceramics depending on the disc type. Metal discs are rated for ferrous and non-ferrous metals. Stone discs are rated for masonry and concrete. Diamond angle grinder blades are used for tiles, porcelain, and hard stone. Each disc must be rated for the specific material and for the RPM of the angle grinder being used.
What size disc should I use?
Disc size must match the size rating of your angle grinder and the guard fitted to it. Common sizes are 115mm for small grinders, 125mm for standard grinders, and 230mm for large grinders. Never fit a larger disc than the grinder and guard are rated for, as this is a serious safety risk. The bore size of the disc must also match the spindle thread of the grinder.
What are TCT circular saw blades used for?
TCT (tungsten carbide tipped) circular saw blades are used for cutting timber, sheet materials, plywood, OSB, and engineered wood products with circular saws and mitre saws. The carbide teeth are significantly harder than standard high-speed steel, giving TCT blades a much longer service life and producing cleaner, more consistent cuts in construction timber and boarding.
What are reciprocating saw blades used for?
Reciprocating saw blades are used for demolition cutting, cutting through timber containing nails or screws, pipe cutting, and making access cuts in walls, floors, and ceilings. Their back-and-forth cutting action makes them ideal for work in confined spaces and for cutting through mixed or unknown materials during strip-out and demolition operations.
What is the D5P Professional Angle Grinder Blade suitable for?
The D5P Professional Angle Grinder Blade is designed for cutting granite and hardstone with an angle grinder. It is available in diameters from 125mm to 230mm with bore sizes from 22mm to 25mm, allowing you to select the correct size for your grinder and application. Choosing the correct diameter and bore ensures accurate, controlled cutting and maximises blade performance on hard stone materials.
What are Phoenix Extra Thin Discs used for?
Phoenix Extra Thin Discs are designed for cutting stainless steel and are suited to tasks where speed, efficiency, and accuracy are priorities. The extra thin profile reduces the amount of material removed per cut (kerf width), which minimises heat generation in the workpiece, produces a cleaner cut edge, and reduces disc wear per cut compared to standard thickness cutting discs. They are the correct choice where cut quality and minimal heat input into stainless steel are important.
Why buy cutting and grinding discs from CMT Group?
CMT Group supplies trade-grade cutting and grinding discs including our own MAX brand range, covering metal discs, stone discs, angle grinder blades, TCT circular saw blades, and reciprocating saw blades. Strong UK stockholding means we can fulfil bulk orders and urgent site requirements with same-day and next-day delivery. Our team can advise on disc selection for your specific material, machine, and application.
Abrasive Discs vs Diamond Discs: Which Do You Need?
Abrasive cutting and grinding discs use bonded aluminium oxide or silicon carbide particles as the cutting medium. They are effective for cutting and grinding metal and general masonry materials and are the standard choice for most site and workshop applications involving steel, pipework, and standard concrete block. They are cost-effective consumables that are replaced as they wear down through use.
Diamond discs and angle grinder blades use industrial diamond as the abrasive, bonded to the disc or blade edge. Diamond is significantly harder than aluminium oxide or silicon carbide, which makes diamond discs far more effective on very hard or abrasive materials such as granite, porcelain, hard stone, and reinforced concrete where a standard abrasive disc would wear out very quickly. Diamond discs have a higher upfront cost but a longer service life on the materials they are designed for, which typically makes them more cost-effective per cut on hard and specialist materials. For standard steel cutting and grinding, abrasive discs remain the most practical choice. For tile, ceramic, hard stone, and specialist masonry, diamond is the correct option.
