Tungsten carbide cutting tool, or tungsten carbide cutter, is any tool that is used to remove some material from the work piece by means of shear deformation in machining.

Tungsten carbide cutting tools mainly includes linear cutting tools and rotary cutting tools. Wherein, linear cutting tools include tool bits and broaches. Rotary cutting tools include drill bits, countersinks and counterbores, taps and dies, milling cutters, reamers, and cold saw blades. Also, there are other cutting tools, such as bandsaw blades, hacksaw blades, and fly cutters, combine aspects of linear and rotary motion.
Tungsten carbide cutting tool is harder than the material which is to be cut, and is able to withstand the heat and force generated in the metal-cutting process. Also, the cutting tool has a specific geometry, with clearance angles designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the workpiece surface. The angle of the cutting face is also important, as is the flute width, number of flutes or teeth, and margin size.
