Nowadays, with the continuous development, improvement and innovation of diamond saw blades, the efficiency of cutting concrete has also been greatly improved, and the common specifications are 7, 14, 16 inch diamond saw blades.
The best 7, 14, 16 inch diamond saw blades for cutting concrete. How to choose it? A good diamond saw blade for concrete can make it work twice with half the effort
1 Blades made of corundum may be cheap, but on a per-cut basis, they are more expensive than diamond blades.
You can use a cold chisel and sledgehammer to make small rough cuts, but a better choice is a circular saw with a special blade.
2 Abrasive corundum masonry blades are cheap. The blades are widely used and can cut concrete and asphalt.
They are able to withstand greater force, but they are not fast and slow. In most cases they can only cut a depth of 1/4 to 1/2 inch. So any cut is time-consuming. They also wear off quickly.
A 7-inch diameter blade will wear down to 6-1/2 inches at the beginning of the cut. After cutting a foot or two lines, it means that you need to adjust the depth of your saw frequently to expose more blades.
The smell of abrasive corundum leaves, which produces fine feather dust, becomes so hot that they can actually glow.
3 The diamond blade is composed of a metal blade and a diamond/metal composite material combined to the periphery.
When the blade is cutting, the metal composite material slowly wears out, revealing a new sharp diamond cutting edge. The standard 7-inch inch diamond blade. Diamond blades are divided into two categories:
① Dry cutting diamond blades usually have serrations or tooth edges to help cool the blade and eject waste. They work best when you do a series of progressively deeper cuts to avoid overheating the blade.
The disadvantage of dry cut stone is the tornado of fine dust it produces. If you cut concrete indoors, seal this area with plastic and duct tape to seal all duct openings.
② Wet cutting diamond blades can have teeth or smooth, continuous circumference. Water not only helps to cool and lubricate the blades, but also keeps the dust down. These cuts are the fastest and cleanest, but they need a special saw that can both dispense water , And use it safely.
As an improvised option, you can stuff your saw into a GFCI-protected extension cord and have an assistant carefully direct a small amount of water in front of your saw.

F: How can I buy the most suitable diamond saw blade?
A: 1. Is the saw blade used for sawing, slicing, or other purposes?
- The hardness, abrasiveness and granularity of the stone. If possible, please provide samples or pictures.
- The machine used for saw blade is bridge cutting, table cutting or brick cutting.
- The main motor of the machine, the number of revolutions per minute of the shaft, the cutting depth and the cutting depth.
- The thickness of the base body with the proper size of the cutter head. 6 Basic requirements for the life of the saw blade The number of squares cut by each saw blade.
F: How do I know how much freight I need to pay?
A: To calculate the total weight of your goods, first choose a transportation method, confirm the current freight rate, then calculate the freight, and finally confirm the other costs and add them up.
F: After we pay, how long can we arrange the shipping?
A: It depends on the order quantity. Our monthly output of cutter heads is: 3 million. Usually, we will ship the goods within one week of receiving the payment. Special products, special consultations. Wanlong will inform the approximate sailing schedule before you place the order.
F: What is the minimum order quantity?
A: Any number of sample sheets is fine. For regular orders, Wanlong hopes that the weight of the ordered products can reach more than 45 kg (airlines have strict requirements on weight, in addition, the freight for goods under 45 kg is very high)
F: If we want to buy your products, can we provide free samples?
A: Wanlong never provides free cutter heads. This is a high-value product per unit, so very few diamond tool companies will provide free samples. If you want to test, please buy. According to Wanlong’s many years of operating history, people will pay more attention to the tools they get after payment. Although the number and amount of samples are relatively small, its cost is higher than that of ordinary products.

F: Which is the best finger drill or oblique straight tooth with curved teeth?
A: Oblique straight tooth finger drill, this design is conducive to chip removal and water flow.
F: What is the difference between the cutting objects of turbine blades and agglomerated dry slices?
A: Compared with agglomerated dry slices, turbine slices have better continuity when cutting, and are suitable for cutting marble. Agglomerated dry slicing, suitable for cutting granite.
F: What is the difference between dry and wet slices?
A: The main difference is: the way the diamond tip is welded to the substrate is different. Wet cutting uses a brazing process. Half of the dry cutting is laser welding. Laser welding has a higher melting point. In addition to the welding method, another difference is: the carcass. The carcass of dry slices is relatively soft, making it easier to cut without cooling water.
