1. Diamond Turbo Cutting Blade by Casaverde – Best Diamond Saw Blade for Cutting Granite Countertop

Despite being very affordable, this cutting blade for Granite can deliver excellent results. It can be used for both dry and wet cutting. However, you will get the best results if you use it with water.

Why Should You Choose this Blade?

This cutting blade is equipped with turbo segments. These are the longitudinal lines found on the blades, and it works by reducing the lateral contact of the piece that you cut and ultimately reducing friction. Because of this feature, it does not produce a lot of dust when it is used dry.

This blade is also equipped with a continuous rim that enables the user to make smooth cuts. This is something that’s important when you are working on Granite because you want to get those precise sleek, and smooth corners to make it look clean and well-cut.

On top of that, several users noted that this blade has enough grinding capacity, mostly when you are polishing the edge of the Granite. It can remove minimal irregularities without needing to switch to a fine grinding disk.

Safety Precautions

One common pitfall in cutting Granite is overcutting. This is why this blade is designed with protective teeth to prevent exactly that. You don’t have to worry about it falling to fill in the grooved area.

Excellent Price

Aside from the features mentioned above, the biggest selling point for this blade is its price. It is considerably more affordable than other brands out there, and it will still allow you to get top-notched results.

What’s the Catch?

This product will dull out faster than the more expensive options in the market. Then again, you are paying only a fraction of a price for this one, so that is a reasonable trade-off. This makes this blade ideal for amateur or occasional users because it will still allow you to get excellent cut quality a few times.

However, suppose you are a professional, and you want a blade that will provide you with longevity. In that case, you might want to keep looking. There are several more suitable options for you ahead.

Pros
  • Affordable price
  • Compatible for both dry and wet use
  • Fast speed
  • Smooth cuts
Cons
  • Not Long-lasting

2. DW4701 Diamond Blade by DEWALT – For Longevity and Durability

DEWALT is a well-known brand of reliable and durable tools, and this diamond blade is not an exemption.

Extended Performance

If longevity is a priority for you, this might just be the blade you are looking for. It has a 350 times longer life span compared to other traditional abrasives.

It is mainly made with cobalt, an innately strong material. It also has large diamond segments that enable it to only cut Granite but also concrete, flagstone, ceramic, or any other material.

Continuous Rim Turbo Design

Aside from its durable material, one standout feature on this blade is its continuous turbo design. This means that this blade has a continuous rim combined with a serrated edge. This makes this blade widely compatible with power tools such as tile saws, circular saws, and grinders.

Cutting PerformancePerformance

It is very easy to cut naturally with this blade. It cut fast, too. However, it does not leave a clean and smooth cut when you use it on human-made stones despite having the ability to cut fast. In fact, it might not have the same cutting ability if you use it on human-made stone then revert back to cutting natural ones.

Also, take note that this blade can be quite aggressive. It may cause small breaks on the surface as if the blade chiseled some of it away instead of making a smooth and precise cut. When you do use this blade, make sure to take your time and get a lot of control over how you work the blade.

You will get the best results if you use water when cutting with this blade. It will reduce the dust and allow the blade to make better and quicker cuts.

Am I Getting My Money’s Worth on this Blade?

This is not the most affordable option out there. In fact, it can be quite pricey. However, when you look at how long you will be able to use it before you have to buy a replacement plus its quality, then it is a product that you can consider as good value for money.

Pros
  • Long-lasting
  • Durable
  • Sharp
  • Works on natural and human-made stones
Cons
  • Cutting performance is not smooth
  • Too thin for many angle grinders

3. 5-inch Diamond Turbo Blade with 5/8 -11 Thread from SHDIATOOL – Best Multi-Purpose Product

This product is a hot-pressed diamond turbo blade that you can use for Granite, marble, tile, concrete, brick, and other types of masonry. It has slanted protection teeth that are 125mm/5-inch in diameter.

Multi-Purpose Design

If you are looking for a blade that does not only make efficient deep cuts, then this one might just be what you are looking for. It can also be used for grinding natural and human-made stones and other construction materials.

Other than that, this can be used for both wet or dry cutting. However, when cutting Granite, you will get the best result from this blade if you use the wet method. It will allow you to cut better without dealing with excessive dust.

Beware of the Possible Flange Issue!

This is a pretty good cutting blade for Granite, but you might experience some flange problems with it, especially when you are using it on a 9-inch angle grinder.

The flange is the part used for mounting abrasive or diamond blades to the saw. This blade is fairly easy to put on and off, but the flange positions the blade slightly outside the grinder guard, which can be a little awkward.

However, this issue can be easily remedied by removing the flange. When you do, you will not have any issue mounting the blade, so it is not a huge deal-breaker.

Is this Value for Money?

This blade’s price is pretty fair, given that it has a decent life span before it turns dull. It also provides excellent quality cuts in terms of Granite, so that also constitutes why it has an excellent value for money.

Suppose you are looking to save and have a big project ahead that requires many tasks involving cutting stones. In that case, SHDIATOOL offers discounts for bulk orders. You can simply directly contact them and see what they could provide you with.

Pros
  • Value for money
  • Great cutting quality
  • Can be used for both cutting and grinding
  • Versatile application
Cons
  • You may experience issues with the flange

4. ADLTTS 7-inch T-Segmented Diamond Blade from ALSKAR DIAMOND – Best for Curved Cutting

When it comes to making angled cuts or circular shapes on Granite, low-quality blades tend to cause a lot of chips. However, that seems to not be the case for the 7-inch diamond blade from ALSKAR DIAMOND.

Cutting Performance

What sets this blade apart from its competition is its excellent curved cutting capability. It can cut very hard materials such as concrete, stone, and Granite without any chipping issues. This is very important if you want to achieve a smooth and clean cut.

Several users also noted that this blade works well on paving stones such as bricks. It can make bevel cuts and angle cuts sharply as well. However, do take note that if you intend to use this blade dry, it will create a lot of dust, so if possible, switch to a wet saw for a more convenient and efficient cutting experience.

Will this Blade Last Long?

According to several users, although this blade is not as aggressive compared to other similar ones, it does last longer. It is able to deep cut thick slabs of Granite without becoming dull immediately. It is also able to make long passes before losing its sharpness.

Furthermore, this blade is sintered diffusion bonded. This is a technique used for joint development that uses solid state atom diffusion so that despite being very thin, the material does not easily break or chip off.

Possible Issue

This blade can create more dust than other blades. This is why if you intend to buy this, make sure that the room that you are working on is fully ventilated. If not, your vision and work environment will definitely suffer. Other than that, this is a pretty good blade.

Pros
  • Creates excellent curve and deep cuts
  • Long-lasting
  • Little to no chipping issue
  • Reasonably priced
Cons
  • Creates a lot of dust

5. 4.5-inch 2-in-1 Turbo Cutting Blade from SHDIATOOL – Most Versatile Design

The 4.5-inch 2-in-1 turbo cutting blade from SHDIATOOL is suitable for both wet and dry use. According to users, when it is used dry, it does not create plenty of dust. However, just like other blades, its best performance for Granite is when it is used wet.

Why Choose the 2-in-1 SHDIATOOL Turbo Cutting Blade?

The major selling point of this cutting blade is its 2-in1 design.

Most of the time, many cutting blades are designed to be thin in order to make precise cuts. However, grinding this needs to be at least ¼-inch thick in order to grind a material properly. But that is not the case for this blade because it can either be used as a grinder or stone blade right thickness for both tasks.

This blade is also versatile when it comes to material compatibility. It works well on multiple materials aside from Granite, such as blocks, bricks, pavers, concrete, and marbles.

Other than that, this blade is designed with holes in the shape of an arrow head. These holes help lower down the temperature during the actual cutting so that the surface will not have any burn marks.

Who is this Blade For?

This blade can be useful for both stone fabrication professionals and regular home DIY users. It is fairly easy to use for cutting, and you don’t need any special skill or experience to cut well using this blade. Some users even claim that they also use this blade for itching and carving.

Is the Price Worth it?

Many users of this blade will agree that it has a reasonable price. The price tag on this one is considered to be in the middle bracket, making it not too expensive but not also cheap. However, it has a long service life to make the best out of it before buying another one again.

Pros
  • Reasonable price
  • Excellent cooling feature
  • Low dust in dry use
  • Long-lasting performance
Cons
  • The large size version of this blade tends to wobble

What is a blade for cutting granite?

Blades for cutting granite are diamond saw blades designed to cut concrete and stone. They are available in different lengths and diameters, depending on the application requirements. Those blades can cut through granite, concrete, masonry, and stones. They consist of high-quality diamond segments welded onto steel backing plates. The blades are designed to withstand the incredible pressures involved in cutting through very hard stones and materials. They can also stay sharp for a number of years with proper maintenance.

The diameter of saw blades used to cut granite depends on the application requirements and specifications governing cutting different types of stone or concrete materials. For instance, if you need to perform heavy-duty demolition work like breaking up large surface areas, then it’s better to get larger diameters that will allow you to achieve your goals faster as they don’t require too much power from the machine but deliver excellent results.

Types of blades for cutting granite

cutting-graniteThere is one important point to be noted in the above information, that is the type of blade for cutting granite. It is very important to use a correct blade when it comes to cutting such a hard material like granite because of its various properties associated with it. Granite contains Quartz and Feldspar which are abrasive even at low levels which require high hardness steel for blades. Some of the different types of blades used are:

  • Abrasive Water jet Blades – this type of blade uses abrasion along with water jet forces thereby increasing productivity by 40% approximately over other methods of finishing but this method can’t be used on denser materials as there will be serious risk involved.
  • Diamond Blades – this type of blade comes in two forms. One form is made out of metal which looks similar to the one that woodworkers use for their tools while another type is made from sapphire and diamond chips are bonded together with a backing material that is flexible but strong enough for its purpose. The feature of being able to bind diamonds into a blade makes it suitable for granite as it has a hard surface like glass.
  • Diamond Discs – these blades are similar in structure with circular discs that consist of thousands of small, specially shaped diamond segments bonded to each other by heat and pressure. Diamonds on such blades can be replaced as they get dull requiring replacement or even completely renewed if need be and any such replacements will result in even more productivity due to new or improved design.

Blade safety precautions

Saw blade manufacturers recommend that their products be used in accordance with a number of key safety principles and good practice guidelines: blades should never be run at high speed unless they are being tested or installed; it is much safer to operate blades at low speed while feeding them into a workpiece.

Overdriving will burn out diamond chips prematurely. The life of your blade depends on load capacity, feed pressure (which differs according to the material), and cutting speed; reducing any of these three parameters will extend blade life significantly. Blades for cutting granite are dangerous and should only be handled by experienced operators.

There is a strong temptation to turn on the blade without having your fingers away from the blade. Cut-off fingers are some of the most frequent industrial injuries and happen when an operator tries to stop a flying blade with one or more fingers; they are also often caused due to excessive carelessness during operation. Just be very careful during the cutting process, and never abuse your blades.

How to choose the right blade for cutting granite

diamond-bladeThe hardness rating of the blade has a direct effect on the force necessary to cut granite. In general, lower hardnesses will require less pressure and so will generate less heat and wear. Blades for cutting granite have to be very hard, to take the high impact force from the granite.

They must also be very resistant to wear. Indirectly, it is possible that a blade becomes too brittle and breaks as a consequence of excessive pressure on a hard stone – but this would be due to insufficient hardness rather than excess.

The best way of finding out how hard a blade should be is by taking an indentation impression with your fingernail or with an etching needle. The impressions can then be compared against a chart that shows all the different hardness ratings in terms of BHN (Brinell Hardness Number). A good blade for cutting granite will have diamond-like carbon (DLC) coating.

Frequently Asked Questions

Can a diamond blade cut granite?

The short answer is: Yes, a diamond blade can cut granite. Granites are igneous rocks and the most common mineral in the Earth’s crust. It forms at high temperatures and pressure deep within the earth. The strength of granite ranges from very soft (scratchable with your fingernail) to extremely hard (harder than any metal). Therefore all granites cannot be equal for cutting purposes.

Diamond blades have been used extensively in this industry and over years they have gained popularity because of their ability to reduce cycle times and production costs. They offer increased productivity as a result of superior resistance to damage during abrasive operations, which results in less downtime due to tooling repairs or replacements. Diamonds are very strong which allows cutting granite in half the time that it would take with other types of blades. Diamond tooling is able to do this by cutting at high speeds while maintaining a smooth, consistent surface finish on the granite.

Will masonry blade cut granite?

Masonry blades are designed to cut a variety of materials, including brick, block, and mortar. However, they are not typically designed to cut granite. If you try to use a masonry blade on granite, you may find that it doesn’t cut as well as you’d like and can even damage the blade.

Can granite be cut after installed?

In general, it is not recommended to cut granite after it has been installed. Granite is a very hard material and can easily be damaged if cut incorrectly. If there is a need to cut the granite, it is best to consult with a professional to ensure that the process is done correctly and safely.

Can you dry-cut granite?

The short answer is yes, you can dry-cut granite. However, the long answer is a little more complicated than that. Granite is a very hard material, and it can be difficult to cut through it without the proper tools and equipment. If you are trying to cut granite by hand, you will need a very sharp blade and you will need to work slowly. Even so, you should expect some major damage if you try to cut through granite without an industrial-rated diamond blade or at least a high-quality wet saw.

Most people are not able to successfully cut granite with home tools because it is too hard of a material. Any dry cutting that can be done will create a lot of dust and debris, so it is recommended that you wet cut instead. A standard diamond blade would be used for this type of cutting.

Conclusion

Any of the blades mentioned above will provide you with excellent cut quality as far as Granites are concerned. However, suppose you require affordable options for amateur use. In that case, you might want to opt for the Casaverde or the SHDIATOOL blades. But if you don’t mind paying for more in exchange for a longer lifespan, go for the DEWALT or ALSKAR Diamond blades.

By the end of the day, it all boils down to your personal preference and requirements. What’s important is that the selection process will not be that time-consuming since the top-picks are already presented to you on the list mentioned above.
