Diamond Grinding Discs
Used for: Removing aggressive material, cutting hard materials, and cleaning and smoothing surfaces.
Grinding discs tend to be thicker, reinforced discs attached to angle grinders or tile cutters. Although discs such as the PREMTOOL Electroplated Cutting and Grinding Diamond Blade can cut hard materials, grinding discs excel at cleaning and preparing material ready for use. For example, the Proxxon Corundum Grinding Disc is great for removing rust, old paint or adhesives. They can also be used to level surfaces, creating an even foundation for your tiles. For better stability when shaping smaller edges, look for grinding flap discs.
Popular brands include: PREMTOOL, Montolit, Bihui, Proxxon, Genesis, Abracs, and Marcrist.

Diamond Tile Files/Hand Pads
Used for: Smoothing and shaping small areas or delicate materials.
Hand-held tile files are a great way to quickly and effectively smooth and shape surfaces. They are commonly used to smooth exposed tile edges, shape edges, or gently remove abrasive residue on the surface of your tiles. Tile files have a durable, grit-coated surface often made from tungsten, carbide, or diamond. Choose your grit level coating, including 60, 120, 200, and 400, to meet your project’s requirements. The advantage of diamond tile files is that they allow greater control over applied pressure, which improves accuracy.
Popular brands include: PREMTOOL, Bihui, Montolit, Rubi, Faithful, Battipav, and Vitrex.
Bullnose Grinding Wheels
Used for: Creating smooth, rounded, and bullnose edging.
These diamond-coated tools are primarily used for edge profiling. They attach to your angle grinder and easily shape, smooth, and round edges to create the look and finish you want. They are highly versatile and compatible with a range of materials, including porcelain, granite, marble, quartz, and concrete. Whether you’re edging countertops, steps, walkways, pool copings, paving, or tiles, bullnose grinding wheels are a great tool for creating that professional finish.

Types of Diamond Blades
As you shop for diamond tiling tools, you may notice different types of blades and discs. It’s important to know each one's features to match the right blade to your project.
Segmented: Features small gaps around the blade's edge that allow it to cut quickly without overheating. Ideal for challenging materials such as brick or concrete.
Continuous Rim: These have one smooth edge and spin quickly to provide clean, precise cuts on delicate materials such as tile or ceramic.
Turbo: The rapid speed of turbo blades ensures a quick, accurate cut of tougher materials. That’s why they’re popular for stone and masonry projects.
J-slot: designed primarily for making fast, smooth, and precise straight cuts in very hard materials, such as porcelain slabs (including 20mm), ceramic tiles, granite, marble, and quartz. They are favored by professionals for creating clean, chip-free edges on high-end materials, often used with wet-cutting table saws or angle grinders.
Mesh: designed for fast, clean, and chip-free cutting of extremely hard materials, most notably porcelain tile and granite. They are characterized by a continuous diamond rim with integrated mesh-like patterns or slots that improve cooling, reduce debris, and increase cutting speed compared to standard blades.
Dekton: Dekton blades are specialised diamond saw blades engineered to cut ultracompact surfaces, sintered stone, and porcelain without chipping. They use a soft bond, fine diamond grit, and a thin, reinforced core for fast, precise, smooth, clean cuts.

Diamond Grit Levels
Another important consideration when choosing the right diamond tool for your tiling project is the grit level. When we say ‘grit’, we’re referring to the size and coarseness of the particles on the surface of your diamond blade or tile cutting disc. These can be a variety of materials such as diamond, sand, or carbide. The level of grit is graded by numbers that indicate the tool's coarseness.
Grit Breakdown:
16-60: A coarse surface with large particles. Designed for heavy-duty materials and can be used for fast cutting, shaping, grinding, and the removal of aggressive materials.
80-150: A medium level of coarseness. This is commonly used for surface preparation by grinding, sanding, or polishing materials.
200-600+: Contains smaller particles, resulting in a fine coarseness. Ideal for detailed work such as honing and polishing on more delicate materials.
800-3000+: Ultra-fine grit level, which is predominantly used for creating a polished, mirror-like finish on surfaces.
As a rule of thumb, lower numbers represent larger, coarser particles. Higher numbers represent smaller, finer particles.

Why Is Diamond Used in Cutting Tools?
Diamond is known for being one of the hardest natural materials. In its raw state, it has sharp edges, and it is this coarse surface that makes it ideal for cutting through tough materials. It is also known for its:
Extreme Durability: Its hardness means it will not wear down quickly, providing continuous cutting performance.
Thermal Conductivity: Diamond naturally reduces heat away from the cutting point, reducing risk to the tool, material, and user.
Low Friction: The lack of friction means diamond tools work faster, smoother, and more efficiently, especially at high speeds.
High Versatility: With different diamond densities (or grit), you can use the right level of coarseness to cut, grind, sand, or polish to achieve the desired outcome.
Premium Finishes: From clean cuts to mirror-like polishes, diamond tools provide reliable results for that professional, premium look.
