The demand for granite tile in kitchens and bathrooms is still high. Granite countertops also remain a popular choice. Cutting this hard natural stone requires the right tool and blade. Many professionals ask, "Can you cut granite with a tile saw?" The answer is a resounding yes. You need the correct setup for a precise, chip-free cut. This guide will detail how to cut granite tile like a pro. We will show you the equipment and steps for excellent results.
Whether it's trimming a piece for a backsplash or resizing a slab for an outdoor kitchen, using the safest granite countertop tools with proper technique ensures clean, precise results in any granite project. From small DIY jobs to larger installations, having the right tools (and knowing how to use them) makes all the difference.
Granite's hardness makes it an excellent building material, but it is tough to cut at home. Granite has a very high density. It contains quartz and feldspar, which are extremely hard minerals. In fact, normal tile cutters will fail and can easily chip the granite tile. This stone requires specialized cutting techniques and tools.
Attempting to cut granite improperly carries risks. You may cause chipping or breaking of the tiles if you don't make straight, supported cuts. The friction can also generate excessive heat. This heat quickly wears down a standard blade. So, you need to reduce chipping and wear on your tool. Specialized equipment (like a wet granite saw with a diamond blade) ensures clean, accurate cuts with smooth edges. Always use the right tool for the job to avoid damage or injury.
Yes, you can cut granite with a tile saw. However, you must use the correct accessories. A standard tile saw designed for ceramic tiles will not work for granite by itself. You must switch to a diamond granite cutting blade for stone cutting. The saw itself provides the mechanism for a straight, wet cut, but the blade is what actually does the cutting on hard stone.
(Feature Comparison: Standard Tile Saw vs. Granite-Cutting Saw)
| Feature | Standard Ceramic Tile Saw Setup | Stone Saw (Tile Saw with Stone Blade) |
|---|---|---|
| Blade Type | Continuous rim for ceramic/porcelain | Diamond blade (continuous or turbo rim) |
| Intended Material | Soft ceramic or standard tile | Hard stone like granite or marble |
| Cutting Power | Less power (designed for softer material) | Higher torque/power is often needed |
| Cooling Method | Wet cutting for dust control and cooling | Wet cutting is crucial for hard granite |
The diamond blade is the critical factor. Diamond is the only material hard enough for cutting granite tile. Blade selection is extremely important for a clean result. Remember this key distinction when preparing to cut granite tile, especially for first-time users at home.
You have two main options for cutting granite. Both the wet tile saw for granite and the wet circular saw for granite will work. However, each device must use a diamond blade and water cooling to handle this material. When making a comparison of granite cutting tools, consider the nature of your project:
A wet tile saw for granite is generally the best choice for most tile cuts. It features a water reservoir and pump. The water constantly cools the blade, and this minimizes friction and wear. It is designed to hold the tile securely on a sliding table. This setup ensures a very precise straight cut without gaps or crooked lines. It excels at cutting granite tile cleanly and safely, essentially functioning as a dedicated granite saw for your workshop.
The wet circular saw for granite is another alternative. It is often used for large granite slabs or complex cuts that a stationary saw cannot accommodate. For example, you might use a circular saw to trim a large outdoor kitchen countertop slab or to cut out a fireplace opening where a fixed saw can't reach. It offers portability and versatility on a worksite, but you must manage the wet cutting process manually. This means you have to ensure there's a constant flow of water aimed at the blade during the cut. This option requires more skill to maintain a perfect cut line. It is useful for installing and fitting granite countertops in place or other situations where you need to move the saw to the material (instead of the material to the saw).
Wet cutting is essential when you cut granite. The wet process achieves two critical things. First, it keeps the diamond blade from overheating, because excessive heat may destroy the blade quickly. Second, the water controls the dust. Granite dust is a health hazard, and wet cutting minimizes airborne silica dust exposure. Therefore, always cut wet when working with any natural stone material. Wet cutting with a proper setup is not only efficient but also safer for you and your tools.
Professional results follow a structured process. You need to follow specific steps to cut granite tile cleanly. Since you'll be using a variety of tools, safety and preparation are paramount.
Always wear appropriate safety gear before cutting. This includes safety goggles to protect your eyes from flying chips. Use ear protection to guard against loud saw noise. Wear heavy-duty gloves for hand protection and a good grip. A respirator or dust mask is crucial to minimize dust inhalation (even with water, some dust can become airborne). Remember, even with the safest granite countertop tools, you must protect yourself with the proper gear.
Measure and Mark the Tile: Measure the area carefully where the granite tile or slab needs to fit. Mark your cut line clearly on the granite using a pencil or permanent marker. For even better results, apply blue painter's tape over the cut line and mark on the tape. This technique can further reduce chipping along the cut. Double-check your measurements to avoid mistakes. Keep in mind the blade has thickness; account for the blade's kerf (cut width) if precision is critical.
Secure the Tile Properly: The tile or slab must be stable before cutting. Use the saw's integrated clamps or separate C-clamps to hold the granite firmly in place. A slight movement during cutting can ruin the cut or cause an accident. Ensure the area under the granite tile is fully supported – use a piece of scrap wood underneath if necessary. If you're cutting a narrow strip (for example, trimming a backsplash piece), extra support is crucial to prevent the granite from snapping. A well-secured workpiece is key to a straight, safe cut.
Use a Continuous Rim Diamond Blade: Select the right blade for the job. A continuous rim diamond blade provides the smoothest edge finish on granite. This blade type is ideal for granite tile and other fine cutting because it minimizes chipping. Make sure the blade is rated for granite specifically (not just for ceramic). Check that your blade is in good condition and mounted correctly (no wobble or warping). Using the proper granite cutter blade here makes all the difference in cutting quality and speed.
Start Slow to Avoid Chipping: Begin the cut at a very slow, controlled pace. Let the diamond blade gradually grind into the granite. Do not force the material into the blade. Slow, steady movement is key to achieving a clean cut. It helps to reduce chipping at the start of the cut line. If the granite is very thick or hard, you can first score the surface along your marked line, then proceed with a deeper cut. The important thing is patience – forcing the saw can cause the blade to bind or the granite to chip/crack.
Keep Water Flow Consistent for Cooling: Ensure a continuous flow of water over the blade throughout the cut. The wet cutting process must be uninterrupted to be effective. This constant water stream cools the blade and flushes away stone debris (slurry) from the cut. Wet cutting prevents the blade from becoming dull too fast or overheating. Before you start, check that the saw's water reservoir is filled and the pump is working, or that your hose attachment is positioned properly. If you're doing a long cut, you may need to pause and verify water is still flowing well. Never let the water run out mid-cut – overheating can happen in seconds without cooling.
Support and Complete the Cut: As you near the end of the cut, support the off-cut section of granite (the part being cut off) with your free hand or a brace (keeping fingers at a safe distance!). This prevents the piece from snapping or breaking off before the cut is finished. Guide the saw through the last inch slowly to avoid chipping at the exit point of the cut. Once the cut is done, turn off the saw and wait for the blade to stop spinning before removing the pieces. Handle the freshly cut granite carefully to preserve the clean edges you just achieved.
Follow these steps precisely for a clean cut through tough granite. With practice, cutting granite tile can become almost as straightforward as cutting ceramic, as long as you respect the material and the tool.
When figuring out how to choose granite cutting tools, remember that the blade choice is the most important part of the process. Choosing the right diamond blade will greatly determine the speed and quality of the cut. The blade's design (and quality) affects how smoothly it cuts through granite and how long the blade will last. You need high-quality, precision tools for this hard material – cheap blades will struggle.
Continuous rim diamond blades are best for granite tile when you need a smooth finish. They have a smooth, uninterrupted edge. This continuous rim minimizes chipping and gives an excellent finish. Turbo rim blades are a hybrid design – they have a serrated rim. A turbo blade cuts faster than a continuous rim blade, but it can leave a slightly rougher edge. Segmented blades are the most aggressive; they have gullets (slots) that improve airflow and cooling. Segmented blades are best for faster cutting of rough materials like concrete or thick stone blocks. However, they tend to leave a very rough, chipped edge on granite or tile. Stick to a continuous rim for fine granite tile work because it provides the cleanest cut. A turbo blade can be used if a small amount of chipping is acceptable and speed is a priority, but it's generally a compromise. In summary, the continuous rim style makes the optimal granite cutter blade choice for most granite countertop tiles or veneer, since it delivers chip-free edges.

Mistakes can be costly when cutting granite. The material is expensive, and an improper cut is irreversible. Remember to check your setup carefully before you begin the process.
Using the wrong blade type is a frequent error. A cheap or incorrect blade will quickly wear out, and it will also produce significant chipping. Always use a dedicated diamond blade intended for granite. Opting for a high-quality blade from trusted manufacturers will ensure it lasts longer and cuts cleaner.
Cutting too fast or dry cutting without cooling leads to disaster. High speed or lack of water produces more friction and heat. This heat quickly destroys the blade and can even crack the tile due to thermal stress. Always cut wet and at a slow, deliberate pace. Never try to cut granite dry. As mentioned, water is absolutely necessary for granite – it cools the blade and controls dust.
Inadequate support can lead to broken tiles. Ensure the granite tile is fully supported on both sides of the cut line. If one end is hanging off unsupported, that loose end can snap off as the cut nears completion. This results in a jagged edge and a ruined tile. Use a solid work surface and clamps to secure the material firmly. Also, don't let the cut piece fall away freely – support it as you finish the cut (as described in the steps above).
In short, use the right blade, keep it cool with water, go slow, and support your work. Avoiding these common mistakes will save you from wasted materials and potential injury.
While cutting granite tiles can be a DIY task for those with the right tools and patience, there are situations where it’s better to call in a professional.
If you need highly precise edges, complex cutouts, or bullnose polishing on a granite piece, a professional contractor can provide that level of expertise. Cutting large volumes of granite tile – such as when installing an entire kitchen's worth of granite countertops – may also require professional-grade tools and skills.
Generally, if you’re comfortable using a wet saw for granite and you follow the proper techniques, you can tackle smaller DIY granite tile projects (like a simple backsplash or a few floor tiles). However, for larger projects or very complex cuts, a professional may be necessary. For instance, trimming a few granite tiles for a backsplash or fireplace surround is manageable as a DIY project if you take your time. On the other hand, cutting a thick granite outdoor kitchen slab to size or making long precision cuts for a countertop might be safer to leave to a pro with specialized equipment. Knowing your own skill level (and your tool's limitations) will help you decide when to do it yourself and when to hire someone.
After you cut granite tiles, the edge will often be a bit rough. A clean cut is just the first step – the cut edge usually needs smoothing or polishing if it will be visible. For granite countertops or exposed edges (such as on a fireplace surround or mantel), polishing is required to achieve a finished look.
After cutting, use granite polishing pads to smooth and refine the edges. These pads are designed with diamond abrasives and they work in a series of grits, from coarse to fine. You typically use them with an angle grinder or a polisher tool to work the edge gradually. Start with a coarse grit to remove saw marks, then move to medium and fine grits. This process removes the roughness and brings the edge to a perfectly smooth finish. Take care to keep the pad moving evenly to avoid creating low spots or burns on the granite. With patience, you can make a cut edge look factory-finished.
At JohnsonTools, we offer a full line of polishing accessories and buffing tools. These high-quality consumables are designed for stone work. They help you achieve a truly professional, smooth finish on your granite edges.
Taking care of your diamond blade will extend its life and ensure it cuts effectively every time. In fact, proper maintenance can make a blade last many times longer than one that's neglected – potentially up to 10× longer according to industry data. Here are some blade care and maintenance tips to keep your granite cutting blade in top shape:
Clean the blade after each use: Once you finish cutting (and the saw is off and unplugged), clean off any debris, slurry, or stone dust from the blade. Granite slurry can harden and clog the diamond segments if left to dry. Use clean water and a soft brush to scrub the blade surface. Removing residue prevents extra friction next time and helps keep the blade cutting freely. Always dry the blade completely after cleaning to prevent rust on the steel.
Avoid overheating the blade: Overheating is a blade's worst enemy. Always use plenty of water for cooling when cutting granite (as discussed, never cut dry). If you're making a very long cut or using a handheld saw without continuous water, make intermittent cuts and let the blade spin freely for a few seconds to air-cool. Excess heat can warp the blade or soften the bonding that holds the diamonds, drastically shortening its life. Keeping the blade cool will preserve its cutting performance.
Dress the blade periodically: If you notice the blade cutting slower or glazing (shiny smooth areas on the rim), it may be time to "dress" the blade. Dressing a diamond blade means cutting into a soft abrasive material (like a dressing stone or an old concrete brick) to expose fresh diamond grit. This process sharpens the blade by wearing away the dulled matrix and uncovering new diamonds. Dressing your granite cutting blade every so often will maintain its efficiency and make cutting easier.
Store the blade properly: When not in use, store your blades in a dry, safe place. Avoid tossing a wet blade into a toolbox or leaving it in a damp area. Moisture can cause the blade's metal core to rust or warp. After cleaning and drying, hang the blade on a wall rack or lay it flat on a padded surface. Ideally, use the blade's original cover or a plastic guard to protect its rim. Proper storage ensures your granite cutting blade stays straight and ready for the next project.
Inspect your blade before each use. Look for any cracks in the rim or segments, or uneven wear. If the blade has missing diamond segments or a bent core, do not use it – it's time to replace it for safety. A well-maintained blade will reward you with faster, smoother cuts and will save you money in the long run by lasting much longer.
Q: Can a ceramic tile saw cut granite?
A ceramic tile saw can cut granite, but only if you use a diamond blade designed for stone. The saw's motor must also be powerful enough to handle the dense granite material. In other words, the tool itself is capable, but you need to equip it with the proper blade and use wet cutting.
Q: Do I need a special blade for granite?
Yes, you need a special diamond blade for granite. Regular ceramic tile blades are not strong enough for this hard stone – they will quickly dull or even burn out. A continuous rim diamond blade is the best for a clean cut on granite tile, as it will reduce chipping.
Q: Is water absolutely necessary when cutting granite?
Absolutely yes. Water is necessary when cutting granite. It cools the blade, reduces dust, and improves the cut quality. Wet cutting also extends the life of your diamond blades by preventing them from overheating. Without water, the blade will overheat, and the granite dust will become a serious health hazard, so always cut wet.
Q: Can I cut granite dry?
You should never cut granite dry. Dry cutting will create excessive heat and friction. This not only damages the blade (and can even cause the blade to fail), but it can crack the granite tile due to heat stress. It also releases a dangerous amount of silica dust into the air, which is very harmful to breathe. Always use wet cutting methods for granite to stay safe and get the best results.
