Rubi Diamond Blades
Rubi diamond blade options are built for clean, controlled cuts through porcelain, tile, stone and hard materials without chipping the job to bits.
If you're cutting expensive porcelain or trying to keep edges tidy for a finish job, the wrong disc will ruin the day fast. A proper rubi diamond blade gives you cleaner cuts, less breakout and better control, whether you need a continuous rim for neat tile work or a turbo diamond blade that gets through tougher material quicker. Pair the blade to the cutter and material, and you will get far better life out of your rubi blades. You will find options here to suit Rubi Tools, plus blades that sit naturally alongside Rubi Angle Grinder Discs & Accessories, Rubi Circular Saws, Rubi Tile Cutters and Rubi Tile Cutter Accessories. Get the right disc in the van and cut it properly first time.
What Are Rubi Diamond Blades Used For?
- Cutting porcelain wall and floor tiles cleanly where chipped edges will stand out straight away on kitchens, bathrooms and high-finish fit-outs.
- Trimming ceramic, slate and stone on site when you need accurate cuts around corners, reveals, sockets and awkward end pieces.
- Running wet cutting blade setups through dense tiles and hard materials to keep heat down and stop the blade glazing over too early.
- Using a rubi turbo diamond blade for quicker work on tougher materials where a bit more speed matters but you still want a tidy finish.
- Fitting a rubi diamond blade 115mm or larger rubi diamond disc to the right machine when small detail cuts or longer bench cuts are part of the same job.
Choosing the Right Rubi Diamond Blade
Sort the blade by material first, then by finish. That is what saves waste, chipping and burnt-out discs.
1. Porcelain Needs the Right Rim
If you are cutting dense porcelain, go for a rubi porcelain diamond blade or continuous rim blade rather than a rougher fast-cut option. Porcelain shows every chip, especially on exposed edges, so a cleaner cutting blade is worth it.
2. Match the Blade Size to the Machine
Do not buy on diameter alone. A rubi diamond blade 115mm suits grinder-based trimming and smaller cut work, while a rubi 200mm porcelain blade or rubi 250mm porcelain blade is more at home on tile saws for longer, straighter passes.
3. Fast Cutting or Fine Finish
If speed matters and the material is tough, a rubi turbo diamond blade will usually clear waste quicker. If the cut edge is on show, a rubi continuous rim blade is normally the safer bet for a neater finish.
4. Wet or Dry Use Makes a Difference
If the blade is designed as a wet cutting blade, use water as intended. It keeps heat down, helps the blade hold its edge and gives a cleaner cut on hard tile. Dry running the wrong blade is a quick way to shorten its life.
Who Uses These Blades?
- Tilers rely on a rubi porcelain diamond blade for clean visible cuts on porcelain where edge quality matters just as much as speed.
- Bathroom and kitchen fitters keep rubi blades handy for shaping splashback tiles, floor tiles and finishing cuts around fixtures and fittings.
- General builders and renovators use a rubi diamond disc when refurbs throw up mixed materials and they need one blade range that cuts clean without guesswork.
- Stone and flooring installers reach for larger diameters such as a rubi 200mm porcelain blade or rubi 250mm porcelain blade on wet saws for long straight cuts and repeat work.
The Basics: Understanding Rubi Diamond Blades
These blades do not cut like a wood saw blade. The rim grinds through tile and stone, and the rim style changes how fast and how cleanly the job gets done.
1. Continuous Rim for Cleaner Edges
A continuous rim blade has an unbroken cutting edge, which helps reduce chipping on porcelain, ceramic and other brittle finishes. This is the one you pick when the cut edge will be seen.
2. Turbo Rims for Quicker Cutting
A turbo diamond blade has a patterned rim that helps it cut faster and clear dust better. It is useful when you need more speed through harder material, but it can be less refined than a fine porcelain blade.
3. Water Controls Heat and Blade Life
Wet cutting is not just about dust. Water cools the rubi diamond blade, helps protect the bond and keeps performance steady on long cuts, especially with dense porcelain and larger diameter blades.
Rubi Diamond Blade Accessories That Keep the Job Moving
A good blade matters, but the right support kit stops poor cuts, wasted tiles and trips back to the van.
1. Blade Flanges and Correct Fittings
Get the right bore and mounting hardware for the saw or grinder. A quality blade fitted badly will wobble, cut off line and chip the edge before you have even settled into the job.
2. Water Feed and Tray Parts
If you are running a wet cutting blade, make sure the saw is actually supplying water properly. Poor flow overheats the blade, glazes the rim and leaves you wondering why an expensive disc has stopped cutting.
3. Dressing Stones
When a diamond rim starts polishing instead of cutting, a dressing stone can bring it back. It is a simple fix that often saves binning a blade that still has plenty of life left in it.
4. Spare Blades or a Rubi Diamond Blade Set
Keeping a second blade or a rubi diamond blade set nearby saves downtime when you switch from porcelain to a rougher material. One blade rarely suits every cut on a full fit-out.
Choose the Right Rubi Diamond Blade for the Job
Use this quick guide to match the blade to the material and finish you need.
| Your Job | Blade Type | Key Features |
|---|---|---|
| Cutting visible porcelain edges on kitchens and bathrooms | Rubi continuous rim blade | Clean edge, less chipping, better finish on brittle tiles |
| Fast cutting through tougher tile and hard materials | Rubi turbo diamond blade | Quicker cut rate, better waste clearance, solid control |
| Small grinder cuts and trimming work | Rubi diamond blade 115mm | Compact size, handy for detail cuts, suits grinder-based work |
| Long straight wet saw cuts in dense porcelain | Rubi 200mm porcelain blade | Stable bench cutting, good cooling, tidy finish |
| Repeat cutting on larger tile saw setups | Rubi 250mm porcelain blade | Larger diameter, suited to wet cutting, efficient on long passes |
Common Buying and Usage Mistakes
- Buying a fast-cut blade for fine porcelain work is a common mistake. It might get through the tile quicker, but you can end up with chipped edges that are no good for exposed finishes.
- Ignoring blade size and bore fit catches people out all the time. If the rubi diamond disc does not match the machine properly, you risk poor tracking, vibration and an unsafe setup.
- Running a wet cutting blade without enough water will shorten blade life fast. Heat builds up, the rim glazes over and cutting performance drops off long before the blade should be worn out.
- Pushing the blade too hard is another easy way to spoil cuts. Let the diamonds do the work or you will overheat the rim, wander off line and chip the material.
- Using one blade for every material sounds cheaper, but it usually costs more in waste and replacements. Match the blade to porcelain, ceramic or stone and the cut quality will be far better.
Continuous Rim vs Turbo Rim vs Segmented Blades
Continuous Rim
This is the one for cleaner cuts in porcelain and ceramic where edge finish matters. It is slower than rougher blade types, but it gives you the best chance of keeping chips and breakout down.
Turbo Rim
A rubi turbo diamond blade sits in the middle. It cuts quicker than a continuous rim and still leaves a decent finish, which makes it a good all-rounder for tougher tile and mixed site work.
Segmented Blades
Segmented blades are more about aggressive cutting and cooling than fine finish. They are useful on rougher masonry-type jobs, but for neat porcelain cuts they are usually not the first choice.
Maintenance and Care
Clean the Rim After Dusty Work
Tile and stone dust cakes onto the rim and affects cut quality. Wipe the blade down after use and keep slurry from drying on if it has been used wet.
Store Blades Flat and Dry
Do not chuck them loose under the van seat with other metalwork. Keep rubi blades flat, dry and protected so the core does not get knocked or warped.
Dress a Glazed Blade
If the blade starts skating and burning instead of cutting, it may be glazed rather than finished. A few passes through a dressing stone can expose fresh diamond and get it working again.
Check for Cracks and Rim Damage
Before each job, inspect the core and rim for damage. If the blade is cracked, bent or missing segments, replace it straight away rather than trying to get one more cut from it.
Use Water Where Required
On wet cutting blades, proper cooling is part of blade care. Good water flow reduces heat, helps the bond last longer and keeps larger blades cutting straight on long runs.

Rubi Diamond Blade FAQs
What's the difference between continuous rim and segmented diamond blades?
Continuous rim blades give a smoother, cleaner cut and are the better choice for porcelain and finished tile edges. Segmented blades run cooler and cut more aggressively, but they are rougher and more likely to chip delicate materials.
Which Rubi diamond blade is best for porcelain?
For most porcelain work, a rubi porcelain diamond blade or rubi continuous rim blade is the safe choice. If the cut edge will be visible, do not chase speed first. Go for the blade built for clean finish work.
Do Rubi diamond blades need water cooling?
Some do, some do not, so always match the blade to the machine and intended use. On wet cutting blade setups, yes, proper water cooling matters. It keeps heat down, improves finish and stops the blade wearing out early.
What size Rubi diamond blades are available?
You will find smaller grinder-friendly options like a rubi diamond blade 115mm, along with larger wet saw sizes such as a rubi 200mm porcelain blade and rubi 250mm porcelain blade. The right size depends entirely on the machine and the type of cut you are doing.
How long does a Rubi diamond blade last?
That depends on the material, cooling, feed pressure and whether you are using the right blade for the job. Used properly, they last well, but force a porcelain blade through the wrong material or run it too hot and you will kill it early.
