Diamond Blade Vs. Abrasive Blade: 5 Comparison Points - Radsen

Which, between a diamond blade vs. abrasive blade, should you use for your project? This is a very common question asked by many people. To answer the question, we compared the two cutting tools on five different aspects: cutting performance and efficiency, blade durability, and size differences. Let’s take a closer look:

You can find more information on our web, so please take a look.

Diamond cutting Blade

A diamond cutting blade is a type of saw blade made of diamond particles on its cutting edge. The cutting surface is very hard and effective on almost any material, including metal, stone, and other masonry materials.

To hold the cutting edge in place, it is usually mounted on a steel core. The steel core is designed for different applications and cutting depths. Diamond blades are often used in construction, fabrication, and even demolition processes.

You can use a diamond blade cutting disc with a circular saw, angle grinder, and other machines that are powered with electricity or gas. They are also available in different sizes to fit the specific needs of your projects.

Abrasive Blade

An abrasive blade is an industrial cutting tool made out of resin-bonded particles on its cutting edge. Unlike the diamond cutting blade, the particles are not diamond but made of other materials such as silicon carbide or alumina.

Abrasive blades can be used for cutting a variety of things including metal sheets and pipes, masonry blocks, stones, and concrete walls. They are also available in different sizes to fit more specific applications.

Because of their abrasive nature, these tools tend to wear out faster than diamond blades. They also do not have a long lifespan and need to be replaced more often than diamond blades. For more about the difference between the two blades, read on.

Diamond Blade Vs. Abrasive Blade

Diamond blades have their advantages and disadvantages over abrasive blades, but so do abrasive blades over diamond blades. The following comparison of diamond blade vs. abrasive blade will help you decide which tool is best for your application:

Diamond Blade Cutting

Diamond blades and abrasive blades do not cut in the same way. In contrast with what many people assume, diamond blades do not cut. Instead, they grind through the material, using slow erosion to cut through materials.

This diamond blade cutting process is known as abrasion, and it relies on the diamond particles in the blade grinding away at the material being cut. An abrasive blade, however, uses a cutting action to cut materials.

In terms of speed and performance, diamond blades are always the better option. They can cut through hard materials such as brick, concrete, stone and ceramic tiles quickly and without producing excessive heat or dust. Plus, you can use water to cool your wet/dry diamond blade to minimize heat and eliminate dust.

Diamond Blade Life Expectancy

Diamond blades tend to last much longer than abrasive blades. The longer diamond blade life expectancy is mainly due to the diamond particles that make up the cutting edge of the blade. The hardness of these minerals makes them less prone to wear and tear.

Abrasive blades, on the other hand, are made with softer metals which mean they will need to be replaced. As an example, you can expect to uses as many as 50 abrasive blades for one diamond blade replacement.

That means two things: one, that you it’s likely that you could end up saving money with diamond blade cutting in the long run, and two, that you won’t be spending your valuable time replacing your tool’s cutting blades. This is especially if you are working on a high-volume project.

Diamond Blade Sizes

When it comes to diamond blade sizes, the options are far more varied than those of abrasive blades. You can find diamond blades in a wide range of sizes, from tiny ones measuring 4 inches for intricate cutting to much larger ones measuring up to 60 inches or more for bigger jobs.

Abrasive blades are typically only available in standard sizes and shapes, with fewer customization options. Generally, you can only use these blades in smaller machines such as grinders, mostly owing to their weaker construction.

Diamond Blade Cutting Depth

When it comes to cutting depth, diamond blades offer much more flexibility than abrasive blades. An efficient diamond blade can make a deep cut into nearly any material imaginable, especially concrete and stonework.

Diamond blades are available in a wide range of sizes, from the small 4 inch blade to as large as 60 inches for masonry wall. That means more options for cutting depths to suit your needs.

Depending on the type of saw used, the diamond blade cutting depth can range from 1 inch when using a 4 inch disc on a handheld tool to as deep as 20 inches when cutting with a 48-inch saw blade.

Diamond Blade Cost

The cost of diamond blades is higher than that of abrasive blades, but they more than make up for it in the long run. Their longer lifespan and superior cutting performance means you can save money in the long, especially if you’re doing a lot of cutting.

Plus, as there are so many sizes available on the market, you can find a diamond blade that will fit your budget. Just to give you an idea, a diamond blade with a diameter of 4-7 inches costs around $50-$90. The diamond blade price for larger sizes inches can go up to $200 or higher.

Abrasive blades cost significantly less than diamond blades, but they simply do not have the same level of cutting performance and durability. So you end up using several blades to complete a single task or project. In addition to costing you more money, that would mean lost time changing blades in the middle of your projects.

Conclusion

To conclude this diamond blade vs. abrasive blade comparison, we must say that diamond blades offer more benefits. They last longer and can cut through even the toughest materials with greater precision. On the other hand, abrasive blades offer a more affordable option for lighter cutting jobs.

Ultimately, choosing between a diamond blade and an abrasive blade depends on your specific application or project. Diamond blades will offer superior performance and a longer life expectancy, making them the better choice in most cases.

The diamond on the diamond saw blade is the hardest substance in the world, using diamond to cut all hard materials that are lower than its hardness，such as stone, such as reinforced concrete, such as bricks, such as tiles and some other decorative materials. So what knowledge do diamond saw blades have? Let's find out through the following articles:

1: The best diamond saw blade needs to be stable, sharp and not easy to crack. Stable means that the flatness of the saw blade is high enough, the substrate is not deformed, and the angle of the blade welding is good. The sharpness means that the diamond in the segment is broken just right, and the cutting ability is strong. The fact that it is not easy to crack means that the cutting object is not easy to crack. The main reason is that because the sharpness of the saw blade is too high, the saw blade will not hit the stone, and naturally there will be less cracking.

2: Cutting accuracy is the biggest difference between high-quality saw blades and ordinary saw blades. In the process of continuous rotation of the saw blade, there will be slight deflection, and when the saw blade start to cut the stone, it is easy to have a large deviation in the cutting accuracy, especially for bridge-type multi-blade combination machine, the quality of the saw blade determines the precision of the cutting stone, that is, the flatness of the stone slab. For the infrared bridge cutting machine, the most obvious manifestation of the cutting accuracy of high-quality saw blades is the accuracy of the length and width of the stone, and the difference between good saw blades is less than 0.2mm.

3: Steady feeding speed cutting is a judgment on whether the sharpness of the saw blade is maintained or not. The cutting feed speed is the cutting speed of the saw blade in the forward process when cutting the stone. Stable cutting first means that the cutting speed is stable and will not appear the situation of fast for a while and then slow, the smooth feeding speed indicates that the saw blade maintains a good cutting ability, the speed can be maintained, and the saw blade will not become blunt or fast because of the speed, indicating that the saw blade is in a good cutting condition.

4: Different groove shapes of saw blades represent different cutting capabilities. The main groove type has a key hole shape. The saw blade teeth of this groove type are separated. When cutting, each tooth has an independent cutting ability, which stimulates the potential of the individual teeth, so it has great sharpness and cutting efficiency. improvement. Then there is the wide U-shaped groove. The wide U-shaped groove and the keyhole groove are similar in purpose, but the U-shaped does not completely isolate the connection between the two saw teeth, so the sharpness will be worse, but the performance of cutting continuity have great improvements. Then there is the narrow U-shaped groove. The saw blade of this groove type has strong continuous performance and is usually used for marble cutting with brittle hardness. Finally, there are saw blade grooves with cross slits and hook grooves. This type of saw blade has a strong continuous cutting ability, but it is somewhat insufficient in terms of cutting efficiency.

5: The different serrations of the saw blade represent the difference in cutting performance. There are many types of saw blades. Generally speaking, the common saw blade segments have M type. Most of these saw blades speed up the cutting. Represents the sharpness and efficiency of the saw blade. Other tooth shapes, including V-shaped, W-shaped, T-shaped reinforced type, corrugated type, etc., are all to increase the special cutting ability of the saw blade.

6: There are two elements of the saw blade base that must be paid attention to: low temperature resistance and high temperature resistance, also known as the expansion coefficient.

In general, diamond saw blades still have a lot of knowledge worth knowing. Only by knowing more, we can master the best cutting method in the cutting process, prolong the cutting life of the saw blade, and increase the overall cost-effectiveness of the saw blade.
