  2. Tungsten carbide - Wikipedia

    en.wikipedia.org/wiki/Tungsten_carbide

    Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering [7] for use in industrial machinery, engineering facilities, [8] molding blocks, [9] cutting tools, chisels, abrasives, armor ...

  3. Burr (cutter) - Wikipedia

    en.wikipedia.org/wiki/Burr_(cutter)

    The cutters depicted in the image, being made of tungsten carbide, can withstand and operate at these elevated speeds. This allows them to function at higher velocities compared to equivalent "HSS" ( High-Speed Steel ) cutters, all the while retaining the sharpness of their cutting edges.

  4. Dental drill - Wikipedia

    en.wikipedia.org/wiki/Dental_drill

    The burrs are usually made of tungsten carbide or diamond. The three parts of a burr are the head, the neck, and the shank. [4] The heads of some burrs (such as tungsten carbide burrs) contain the blades which remove material. These blades may be positioned at different angles in order to change the properties of the burr.

  5. Cemented carbide - Wikipedia

    en.wikipedia.org/wiki/Cemented_carbide

    The first cemented carbide developed was tungsten carbide (introduced in 1927) which uses tungsten carbide particles held together by a cobalt metal binder. Since then, other cemented carbides have been developed, such as titanium carbide, which is better suited for cutting steel, and tantalum carbide, which is tougher than tungsten carbide. [1]

  6. Annular cutter - Wikipedia

    en.wikipedia.org/wiki/Annular_cutter

    A tungsten carbide tipped (TCT) and high-speed steel (HSS) annular cutter (also known as a "core drill" or "hole saw"). An annular cutter (also called a core drill, core cutter, broach cutter, trepanning drill, hole saw, or cup-type cutter) is a form of core drill used to create holes in metal.

  7. Drill bit - Wikipedia

    en.wikipedia.org/wiki/Drill_bit

    Tungsten carbide and other carbides are extremely hard and can drill virtually all materials, while holding an edge longer than other bits. The material is expensive and much more brittle than steels; consequently they are mainly used for drill-bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal.
