Diamond Grinding
The Versatility of Diamonds
Whoever said diamonds are a girl's best friend clearly never had to mitre a piece of ultra-hard porcelain on a Friday afternoon!
Despite what the name might sound like, diamond grinding isn't about grinding up precious gems. Instead, it refers to specialised trade tools that are infused with microscopic industrial diamond particles bonded to a metal or resin base. Since diamond is the hardest natural substance on Earth, embedding these synthetic particles into tool heads allows professional diamond grinding tools to make full use of the stone’s unmatched hardness and toughness. Instead of brute-force hammering that micro-fractures your surfaces, diamond grinding smoothly scratches parallel across hard materials like stone, glass, ceramic, and concrete to level, shape, and finish them without wearing down your gear.
Heavy-Duty Tile Grinding Equipment & Accessories
At Tilers Online, we’ve been supplying the Australian trade since 1998, so we know what gear holds up under pressure. We stock a comprehensive range of tile grinding equipment and high-performance diamond grinding discs Australia-wide to tackle every stage of your project.
Grinding Cups & Wheels
Looking for the best diamond wheel for smoothing concrete or taking down stubborn adhesive ridges? Our diamond grinding cups and heavy-duty concrete grinding cup wheels make light work of substrate prep.
Flap Discs & Flap Wheels
Ideal for dry use on standard angle grinders when you need to handle mitring, bevelling, or shaping porcelain, ceramic, and sintered stone on the fly.
Edge Wheels & Bullnose Bits
Master how to grind porcelain tile edges with ease. Use specialised tile edge grinding wheels and bullnose bits for smooth round-edge profiles on skirting, steps, and pool copings.
Mill Bits & Cone Bits
Need to adjust a hole that’s slightly out of alignment? Grab high-precision Rubi diamond mill bits or an M14 diamond cone bit for stone. These specialised bits aren't meant for drilling new holes, but they’re awesome at enlarging, shaping, and cleaning up pre-drilled holes to prevent stress cracks around pipes.

Frequently Asked Questions About Diamond Grinding Tools
What is the difference between a diamond blade and a diamond grinding cup wheel?
Diamond blades feature thin cutting rims or segments designed to slice straight through material. In contrast, a cup wheel has a wide face embedded with diamond segments meant for grinding, levelling, and shaping surface tops.
Can I use diamond grinding wheels dry, or do they require water cooling?
Many modern grinding tools — like diamond flap wheels and cup wheels — are engineered for dry use directly on your angle grinder. However, wet grinding with water helps keep heat down, reduces airborne dust, and can significantly extend the lifespan of your tool when working on ultra-hard porcelain or stone. Always check the specific product label before running it dry.
What are diamond mill bits and cone bits used for?
Specialised tools like Rubi Diamond Mill Bits or an M14 diamond cone bit for stone are NOT designed to drill fresh holes into tiles. Instead, they are built to modify, enlarge, bevel, or polish the inside edges of holes you've already drilled. They're a lifesaver when a tap outlet is slightly off-centre or when you need to bevel a hole edge to stop porcelain from cracking under tension.
How do grit levels affect the finish on tile edges?
Coarse grits remove material quickly; fine grits (these have a higher concentration of diamond particles) produce smoother, polished edges. Start coarse and finish fine for best results. When shaping an exposed edge, start coarse to create your profile, then step up through finer grits before final polishing.
