Different materials use different drill bits. For example, for reinforced concrete, you need to use the best core drill bits for reinforced concrete. A good drill bit can effectively improve work efficiency.
Wanlong Diamond Tools: The best core drill bits for reinforced concrete
1 High effciency, long life and no breaking of segments
2 Sizes of adaptor for threaded bit:M14,M16, G1 2 “,5 8 “-11
3 Applicable for drilling of brick wall,granite, concrete with steel
So how to choose a drill?
1. For soft, medium-hard and complete and homogeneous hard rock formations, surface-inlaid drill bits are generally suitable; for hard, hard and broken, uneven soft and hard, fractured and highly abrasive rock formations, impregnated drill bits should be used. .
2.The hardness of the matrix should be selected according to the abrasiveness, degree of crushing, hardness, granularity and other factors of the rock formation. The main factors are the abrasiveness and crushing degree of the rock formation.
The hard matrix should be selected for rock formations with strong abrasiveness, severe crushing degree, softer, and coarse particle size. On the contrary, the selected matrix should be biased for rock layers with weak abrasiveness, complete homogeneity, high hardness, and fine particle size (such as slipping rocks). soft.
If there is a conflict between abrasiveness and hardness, it is subject to abrasiveness. For example, when encountering a rock formation with strong abrasiveness and hardness, a special hard matrix should be selected. Otherwise, the matrix will be quickly worn by the rock layer and the drill will lose its working ability.
3.The rock formation is complex, the abrasiveness is stronger, and the harder, the better the diamond grade should be selected, and the finer the diamond particle size should be.
4. The rock formation is highly abrasive, relatively broken, and coarser. Choose a carcass with a higher concentration.
5. The rock formation is soft, broken, and highly abrasive, and the matrix is hard. If the impregnated drill bit is used, the water cross section of the nozzle of the drill bit should be large, and the multi-mouth drill bit should be used. On the contrary, the less-nozzle drill bit should be used.

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: We sell saw blades in large quantities in our country, and we only sell them under our own brand logo. Can you put our logo on the saw blade?
A: We hope that you can mark Wanlong on the saw blade, because Wanlong is also a well-known brand in the diamond industry. However, if you insist on printing your company’s logo, we will do it for you, but one percent of the entire saw blade amount will be charged.

A: Yes, we have a slab cutter-infrared automatic bridge stone cutter and integrated bridge stone cutter with the additional function of inclined cutting (0-50 degrees), you can choose manual or automatic. This is an optional feature.
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.
