Diamond stone saw blades are the diamond tools that practically used for cutting granite, marble, sandstone, basalt and other natural stone blocks, slabs and tiles. The diamond stone saw blade is also well known as diamond cutting disc, diamond saw blade, diamond cutting blade. Diamond saw blade isn’t anything new as it has been the primary cutting and grinding stone for decades. Diamond saw blade, as the name suggests is used for cutting and sawing stone for various purposes. Different diamond segment formula are welded on blade core in order to deliver the right cutting results. For medium size saw blade(250mm to 600mm), diamond stone saw blade is a power tool used for cutting various granite, marble, limestone, ceramic, concrete, and many more super hard material. There are different kinds of diamond saw blades including small hand-held cut-off saw, angle grinder saw, table saw, brige cutting machine, stone block cutting machine. The diamond stone saw blades often been used on stone saws, such as angle grinder machine, stone bridge machine, block cutting machine, this means that they have diamond segments welded on steel blade blank to the main working component of the saw blade. The major resistance produced in cutting stone materials like granite and marble cause the high temperature and dust, it requires the technology to be cooled down the diamond stone saw blade and remove the chipping out, prolong their life and decrease the amount of dust. The operator of the diamond stone saw blade must be qualified to do the job, because it requires skilled experience in operating the stone machine.  For other hard material to be cut, use different diamond saw blades. There is unique diamond saw blade to match the exact requirement of every object to cut. Related Articles: a. Best stone diamond saw blade supplier? b. How to choose the right diamond saw blade? c.

Before start to cut, wear gloves and eyeprotection. 1. Buy the laser welding diamond cutting blade, the blade core contain cooling holes, it maybe clearly marked for dry cutting on blade. 2. Remove water tube from the cutting machine and turn off the electric water pump. 3. When start to cut, do not cut deeply at the very beginning, better cut step by step for the dry cutting. For the thick or deep cutting on concrete, keep the concrete cutting blade moving up(not cutting) and dropping down(cutting), this can let the diamond concrete cutting blade cool down. 4. Dry cutting only in large open areas, keep air flowing.

Sometimes in the world of concrete core drilling we face the frustration of loosing a core bit segment or two while drilling, more times than not it’s that urgent job that must be done NOW. So let’s take a look at WHY this might happen. This is written in regards to wet series concrete diamond core drill bits Manufacturing Fault One possible cause could be that a core bit segment might not have been brazed or laser welded on properly. If this is the case, the diamond core bit segment will more than likely come off within the first hole. Usually in the first 50mm depth of cut. To determine if this is the case, where the core bit segment is missing from the barrel, it will look and feel smooth. You will notice that the diamond drill segment is also rather smooth on the surface that was welded to the core barrel. This is most likely with brazed core bits. Don’t assume that just because a segment has come off drilling your first hole that it is a manufacturers fault. It can just be unlucky that it was your first hole and something within the slab or material has caused it to happen, which leads to the next possible causes. 2. Debris and loose particles. More often than not, a diamond core bit segment comes off or breaks because of debris within the hole you are drilling. This could be a piece of reinforced bar that has somehow become lodged between the segments while drilling. It could be something else like a piece of stone thats been dislodged. Sometimes it is hard to determine exactly what caused it to break off in this instance. If the diamond core drill bit has been used numerous times and then a diamond core bit segment comes off while drilling into the material it is safe to say that it is not a manufacturing fault. 3. User Error Yes, it could actually be your fault! Have you got water flow while drilling? Are you using the correct drill type and speed for the diameter size? Are you applying too little pressure to cause vibration? If your drilling through a concrete slab, are you pulling up before it hits the fill or debris beneath? Do you feed enough water? There are many reasons why diamond core bit segments can break or snap off. The above were just a few examples which came to mind while writing this.

Diamond blades work best when cutting wet. The water will prevent the diamond blade from overheating and distorting in shape, it reduce harmful dust created by cutting, and will remove the slurry from the cut. Diamond cannot withstand the forces involved at the elevated temperatures of dry cutting ceramic and abrasive materials, and will be subject to rapid tool wear and possible failure. Blade life is greatly extended by wet cutting. However, many saw blades are designed to operate either wet or dry. Dry diamond blade should be limited to situations where water isn't available easily or used in electrical saws machine. When doing dry cutting, the diamond blade should be allowed to cool off periodically. Cooling can be increased by allowing the blade to spin freely out of the cut. Cut this way for a few minutes, then you should start to see the cutting surface get some shape back, this causes the bond to wear away and expose the diamonds which do all the cutting. This allows cool air to pass between the segments. Dry diamond blade cutting is dangerous for persons unfamiliar with the risks and process. After choose the right diamond blade, how to let diamond blade to cut faster? If the blade starts to cut slower than normal, the best way to adjust this problem is to find a hard surface like cured concrete and drop the level of water you are pumping over the blade. Cut this way for a few minutes, then you should start to see the cutting surface get some shape back, this causes the bond to wear away and expose the diamonds which do all the cutting. Sometimes, people found their diamond blade is easy to distort. Many people apply more pressure to the saw to force the blade harder into the material when it’s not cutting as fast as they would like, but this can cause the blade to overheat and distort in shape, throw a segment, this is unsafe for the operator and bad news for the diamond blade. Generally speaking, it is better to cut with water if the condition allows.

Generally speaking, cutting hard or abrasive subjects such as granite, marble, brick, concrete, asphalt, steel and other similar subjects, diamond circular saw blade has carved a nice in the global industry for the outstanding performance in cutting. Choosing the right diamond saw blade for cutting is necessary condition to perform a cutting task well. Before buying diamond circular saw blades, you should consider the following items, 1. What material you are cutting? The match of the diamond circular saw blade's features as closely as possible to the material you are going to cut, for example, cutting stone, granite, marble, concrete, asphalt, and so on. Correctly identifying the material you are going to cut is the most important factor in choosing a blade. 2. Choose wet or dry cutting? When using power tools such as power hand saw, it is not safe to use water because of the electrical power source. However, diamond circular saw blades for concrete are usually for wet cutting because the concrete to be cut is very hard or abrasive. If the diamond circular saw blades are used without adequate water, the diamond segments themselves may break or the steel core below the segments may wear and break, and then the segment may fly out and may hurt the operator or people nearby. If you have to perform dry cutting for some reason, you should choose sharper diamond circular saw blades, and the dry cutting should be intermittent and shallow to keep the circular saw blade cool. 3. What is the height of diamond segment? Total diamond segment heights may be misleading because of non- diamond bearing segment bases necessary for the laser welding or brazing process. Many other factors affect a blade’s performance and consequent value. Consider the diamond size, concentration and quality, the hardness of the bond, the cutting power (torque) of the saw, and how well the circular saw blade specification is matched to the material being cut. 4. How to choose optimum performance tools? Is it the initial cost of the blade or the total saving cost? For larger projects or regular use, a higher priced blade will actually be less expensive to use because it will deliver the lowest cost per cut. For a small cutting job, you can buy the economy saw blade or cheap diamond circular saw blade.
