7 Best Diamond Blade for Cutting Granite

Diamond blades are made from high-quality steel, and as the name would suggest there are actual diamonds embedded in the blade. They’re not the same diamonds found in engagement rings. These shiny gems are all synthetic. This allows for control over key characteristics, such as crystal shape, size, and strength. While commonly referred to as cutting tools, diamond blades are actually grinding tools. As the blade rotates, the exposed diamonds on the surface of the blade grind the material into a fine powder. That’s why for better understanding this article will illustrate the best diamond blade for cutting granite including other materials with a clear elaboration of specs, features, pros, and cons.

When it comes to cutting hard materials like natural stone, granite, masonry, and concrete, knowing which blade to use can help save you time on the job and prevent the possibility of material waste. While abrasive blades are an inexpensive option, they can wear out fast. Diamond blades will cost you more upfront, but they have a much longer lifespan. The additional cost will balance out in the long run, especially when you factor in the time you’ll spend swapping out blades.

How to Choose the Best Diamond Saw Blade?

Once you’ve made the decision to use a diamond blade for cutting granite, there are a few things you will need to know in order to select the best blade for the job. This includes the type of material you plan to cut, the equipment you’ll be using, blade size, and whether you’ll be cutting wet or dry.

Cutting Speed

The exposed diamonds will eventually fracture from pressure and heat and will fall from the blade. As the segment that the diamonds are bonded to wear, more diamonds are exposed allowing the blade to retain its effectiveness. As the operator will cut at a slow pace or quick, the more the pace the quick the diamond to wear out, and eventually there are fewer expected years. So, choose according to the pace of work and operation.

Types of Blades

There are many different types of diamond blades on the market, but the ones most common in the hardscape industry are Segmented, Serrated, also known as Turbo blades, and Continuous.

  • Segmented Blade: Segmented blades typically have medium to hard bonds and produce the strongest cuts. The cut-outs between the segments make these blades useful in dry-cutting applications since the air flowing between the segment helps to cool the blade while cutting. Segmented blades are commonly used in concrete pavers, masonry, and asphalt.
  • Serrated/Turbo Blade: Turbo Blades are essentially a combination of the best qualities of segmented and continuous rim blades. The continuous, serrated rim design allows for cleaner, quicker cuts by forcing the material out of the way as the blade rotates. It also aids in cooling the blade by allowing air to flow between the cutting surface and the material being cut. Cooling is also aided by holes scattered around the steel core of the blade. Serrated turbo blades can be used in both wet and dry applications. With soft to medium bonds, they are useful for cutting tile, natural stone, marble, and granite.
  • Continuous Blade: Continuous Blades, with their softer bonds, are best for cutting hard materials that can chip easily like porcelain and ceramic tile. They also cut the cleanest, making them ideal for cutting surfaces that will remain exposed as with marble and granite. The slowest cutter of the bunch, are referred to as wet cut blades. Since this style rim does not include segments or serrations, water is used to keep the blade cool, which helps extend its life.

Blade Size

In order to cover the variety of saw designs, blade sizes used in the hardscape industry usually range between four and 14 inches in diameter. So, your grinder size along with the design structure will tell you which you need to cut your materials. grinder size

Bond Strength (Hard/Soft Blades)

Each style of the blade may be available in one or more types of bonds. The bond is a mixture of metals that hold the diamonds in place and different bonds have different wear rates. This is why diamond blades are referred to as hard, medium, or soft. As a general rule of thumb, softer materials use harder blades and harder materials use softer blades.

What’s the Difference Between a Wet and a Dry Cut?

Wet cutting as the name implies uses water to assist the blade in cutting through thick tiles, reinforced concrete, metal, bricks, and other masonries. Wet blades are less prone to overheating and blade wearing, so they’re often used for long, continuous projects. This method of cutting with water also reduces the respiratory risks and other health hazards caused by dust particles since the water also turns a lot of the dust particles from the cut into a slurry.

Dry cutting on the other hand is ideal for indoor use or in work areas where the presence of a water source is uncertain. In contrast with wet cutting, dry cutting is intended for intermittent and small-scale cutting. The main reason for this is that the blade needs ample airflow by allowing it to gradually spin to a stop between cuts. This reduces the risk of either the tool or the blade overheating. These blades are ideal for shaping, detailing, and finishing through deep cuts can also be achieved with the proper precautionary measures.
