The big consideration that most people will be making when considering how much to spend on darts is what is their goal?
 

50-70% tungsten dart will usually cost less than $40 and will be sold at larger chain stores and sporting goods stores. You really have to watch out for cheaper, mass produced imports in this category.  These will be very common, but not the best darts for the long haul.

80% tungsten dart will usually cost $20-$50 and would be considered these the most common darts sold to league players. Many of the players in our lower conferences (newer, inexperienced, shooters) use these darts.

90% tungsten dart will usually cost $50-$100. These darts are most common with guys in the league. They have worked on their game some and have slipped into a pretty consistent way of shooting. There are numerous manufacturers to choose from with a wide variety of models, this is where an individuals feel will come into play. You really need to pick a few of these up and see what is the most comfortable for you.

95-98% tungsten dart will usually cost more than $100 to purchase, not running more than $200 on a consistent basis. These darts will be extremely thin and if you have real potential for developing your game into an elite shooter，it will suitable for you.

According to the tool structure, tungsten carbide CNC tool can be divided into the followings: 　　
Integral: The tool is integrated by a blank made of, regardless of the body; 　　

Welded type: welding method to connect, sub head and shank; 　　

Machine clip: Machine clip and translocation can be divided into two bits can not turn; usually CNC machine tool using clip-on! 　　

Special Type: as composite tools, shock-type tool.

Natural granite fishing weights are a good choice because they look like a natural part of the environment. The natural stone weights are smaller than comparable lead weights because they absorb water and get heavier.

Since tungsten alloy fishing sinker introduction to the fishing market, anglers everywhere have found Tungsten weights to be a far superior product to their lead-based predecessors. Tungsten's higher density allows these sinkers to outperform lead sinkers twice their size. Furthermore, tungsten has low bioavailability and does not pose a pollution risk.

So as for density, tungsten alloy fishing sinker is outweigh granite fishing sinker.

Tungsten carbide CNC tool can be divided into conventional tools and modular tooling two categories. The modular tool is the developmental direction. The main advantage of developmental modular tool are the followings:

1.Reducing tool change downtime, increase production and processing time;

2.Accelerating tool change and setup time, improve the economy of small batch production;

3.Improving standardization and rationalization of the tool;

4.Promoting the management and flexible processing tool level;

5.Expanding the utilization of the tool, give full play to the performance of the tool;

6.Effectively eliminating work disruptions measurement tool, can be preset outside the line.

In fact, due to the development module of the tool, tungsten carbide CNC tool has formed a three systems, namely turning tool systems, drilling and boring and milling tool system tool system.

Bismuth is a brittle metal and fairly rare. Fishing tackle made from bismuth usually is a bismuth tin alloy. Twenty-five per cent lighter than lead, bismuth weights will sink more slowly than a lead weight.

Tungsten alloy fishing sinker is smaller than conventional weights, create twice the sound of lead weights and maintain their shape for longer. The advantages to weights made of Tungsten alloy include the size and hardness of the weights. Another advantage of a Tungsten weight is Tungsten is harder and allows for more feel by the angler.

For the best option, tungsten alloy fishing sinker is better than bismuth fishing sinker in terms of its ability of sinking fast.

Just about any sport equipment needs to be cleaned regularly to remove sweat, dirt, etc., yet it never occurs to most people that their tungsten darts also need cleaning.

To greatly extend the useful life of tungsten darts, clean them regularly. Any mild cleaner that can remove oil will do: moist towelettes (wipes) are great (alcohol based ones not the ones that contain hand lotion!) or hand soap.

By cleaning tungsten darts you will not only make them last longer, but will also restore much of the grip by removing both the slippery feeling and the particles filling-in the hollows of the knurling.

Through processing practice, summed up the other process measures in grinding sharpening can effectively prevent or reduce tungsten carbide blade grinding crack sharpening process.

Less rigid shank, the tool will hold less instably. It may cause the spindle run-out produce grinding cracks, so the machine tools, grinding wheels, fixtures and tooling consists of processing the system should have sufficient rigidity, and should be controlled Axial and radial run-out wheel. Factors causing cracks sharpening tungsten carbide tools produce more, only the appropriate choice of wheel, while using the grinding process fair, in order to avoid cracks, progressive grinding quality.

Due to processing practice, summed up the measure that adopting fair amount of grinding sharpening can effectively prevent or reduce tungsten carbide blade grinding crack sharpening process.

If there are too much friction in tungsten carbide tool grinding sharpening process, grinding can lead to a sharp rise in temperature, the blade prone to burst, so fair selection of grinding parameters is very important. A fair amount of common ground: peripheral speed v = 10 ~ 15m/min, feed f vertical = 0.5 ~ 1.0m/min, f cross = 0.01 ~ 0.02mm / trip. When hand grinding, longitudinal and cross feed volume is not too large.
