The term drill-bit tip infers that they are either fixed or brazed at the edge of another material. This other material is often lacking as much strength as Tungsten carbide. Many precision drill bit designs are tungsten carbide drill bits. They cut this compound into smaller scales with diameters as tiny as 1.5mm to even 0.6mm.

Tungsten is one of the world's most affordable metals. Normal tungsten rings seldom go above a few hundred dollars. These tungsten rings often sell for a price in the ballpark of $200. Tungsten …

Tungsten rings are usually made with a comfort fit, which runs ½ size larger than standard fit rings. For example, if you normally wear size 7 rings, you should order a 6.5 ring with a comfort fit. However, for wedding bands wider than 8mm, you can order your standard ring size, as these rings fit more snugly.

Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the powdered …
