Grinding creates the greatest hazard as the exposed tungsten/thoria area is greatly increased and fine particles of potentially radioactive dust are released into the atmosphere.
It is recommended that a dedicated grindstone with local dust extraction is used, and a simple filter mask is worn unless the number of electrodes used is very small (less than about 20 per year). If the grinding wheel is not fitted with a protective viewing screen, eye protection should be worn. The air extract from the grindstone should be arranged so that the particles are deposited into a substantial disposable bag.
A safe method of collecting and handling the dust from the collection unit must be used to minimise release to the atmosphere (for example, it could be placed in a sealed paper/plastic bag.)
The area round the grinding wheels should be cleaned daily with a vacuum cleaner to remove dust particles. If a high efficiency vacuum cleaner is not available, then the material should be damped down to minimise dust.
Workers should be encouraged to wash their hands before using the toilet facilities, and before taking work breaks, and for this reason the washing facilities should be close to the work areas.

Tungsten carbide coats the edges of blades for reciprocating saws, such as jigsaws and demolition reciprocal saws.
The back-and-forth sawing motion of these types of saws is well-suited for abrasion, and their coating of tungsten carbide grit allows them to grind through metals, ceramics and masonry.
Applications include removing cast iron pipes and metal fasteners during demolition or cutting access holes through stone and tile during remodeling.

Soldering Picks are used to move solder pieces into position when applying heat. The special Tungsten metal won't stick to the solder or the metal so the solder stays where you put it. Tungsten has a sky high melting temperature of 4,470°F. It is excellent for use with platinum and the only metal where contamination is virtually impossible. Tungsten may be bent to the desired angle without breaking, and also works great with Gold and Silver.

Drill bits is a kind of solid tungsten carbide or tipped with it to provide the speed, accuracy and wear resistance required by machine shops and high-precision manufacturing applications.
Construction professionals and amateurs buy similar bits that attach to hand power drills, drill presses and hobbyist rotary tools. Precision drill bit and grinding tools with tungsten carbide tips might be used for milling or sculpting metal as well as decorative carving of stone and precious gemstones.
As materials scientist Dale Wittmer stated in a Southern Illinois University publication, "Tungsten carbide tools have been the standard for over 50 years in the mining industry."

Tungsten Fishing Sinkers,Alternatives of Lead Fishing Sinkers

Fishing tackle industry continues to produce lead fishing sinkers. Lead-based paint has been banned in many places and at one point, lead ammunition for waterfowl was under assault from the Environmental Protection Agency. However, concerns for aquatic environments, clever fishermen and innovative marketing have succeeded in bringing about a rise in the popularity of no-lead fishing sinkers.
The cost of production materials is a primary concern for manufacturers of fishing sinkers. For some, processing other types of metal or metal alloys might require re-tooling molds and dyes that are only suitable for lead. However, several manufacturers have gone to alternative metals and market no-lead sinkers by promoting benefits that their product affords fishermen. One of the more widely used alternative materials is tungsten, which is more expensive than lead, but has properties that set it apart.
According to Wolf Tech, tungsten sinkers are smaller than lead sinkers of the same weight. This could reduce the likelihood of getting snagged on underground structures or rocks. Tungsten sinkers make more noise than lead when hitting the water, which can draw the attention of fish. In addition, several manufacturers produce tungsten sinkers in a variety of colors, which is another feature that's not available with conventional lead sinkers.
In contrast to softer lead sinkers, tungsten maintains its shape over time, is more brilliant than lead and is considered environmentally safe. Tungsten is a good choice for fisherman looking for indestructible no-lead sinkers.
